Carried from Yamato to the northern province of Etchū, the Uda smiths kept a masame-laced tradition through two phases — the founding Ko-Uda generations of the Nanbokuchō, and the long Uda line that worked the forges into the late Muromachi.

The Etchū Uda School (宇多) Lineage
The The Etchū Uda School (宇多), active 1310–1596 in Etchū Province across 48 documented smiths: 0 Kokuhō (National Treasures), 1 Jūbun, 4 Jūbi, 1 Tokubetsu Jūyō, 120 Jūyō.
Phase 1 · Ko-Uda (古宇多) · 1310 – 1394
Ko-Uda (古宇多) names the founding stratum of the Uda school, the work that does not descend later than the Nanbokucho period and so stands before the long Muromachi continuation that the same studio names would carry. The setsumei place the origin in Yamato: around the Bunpo era at the close of Kamakura, the monk-smith Ko-nyudo Kunimitsu left Uda District in Yamato and settled at Utsu in Etchu, and from him the lineage took root. His sons Kunifusa and Kunimune are recorded, and across the *Juyo* and *Jubi* explanations the active founding hands are listed together as Kunifusa, Kunimune, and Kunitsugu, the generations that worked through the Nanbokucho period before the name-bearing successions ran down into late Muromachi. A signed Ko-nyudo Kunimitsu is hard to fix among several smiths who used the name; the *Tokuju* tachi is read as the founder precisely because it shows the most archaic character of the surviving examples, earlier even than the Kunifusa pieces taken for Nanbokucho.
The early steel is the school read at its source. The forging is *itame* mixed with *mokume* and running *nagare-hada* that tends to stand (*hada-dachi*), *ji-nie* adhering with *chikei*, and over it a whitish *shirake-utsuri* or, on the founder's own work, a *nie-utsuri*; the *jigane* carries a blackish, golden-toned cast that the explanations call a northern-province feeling. The temper sits in narrow to *chu-suguha*, opening into *ko-notare*, *ko-gunome*, *ko-midare*, and *togariba*, with *ko-ashi* and *yo* and *ko-nie* well set; along the *habuchi* the Yamato signature of *hotsure* and *kuichigai-ba* appears, while *kinsuji* and *sunagashi* run through. Against the later Uda generations, the Ko-Uda face is the purer one. The *Tokuju* founder is appraised as workmanship entirely like Yamato; the Hie Shrine and Kurokawa tachi by the shodai Kunifusa hold a tight, clear *nioiguchi* and a bright forging, and the *nie* in the best stands strong and rounded where the later hands run coarser and more provincial. A Soshu lean exists, traced to the study of Norishige and Go, yet in this phase the steel and *nioiguchi* keep returning the blade to Yamato roots rather than dissolving into them.
To *kantei* a Ko-Uda blade is to catch the standing, whitish *jigane* with its *masame* tendency and *utsuri* beneath a *suguha* that might otherwise recall Yamashiro, and to bring a *nie*-rich, *chikei*-laden example home from Soshu by the dark steel and the subdued (*shizumi*) *nioiguchi*. The named early hands recur across the corpus: the shodai Kunifusa, fixed against dated pieces no earlier than Koo 1 (1389) and the calligraphy of the lattice-broken 国; the signed Ko-Uda Kunimitsu and Ko-Uda Tomonori of around Meitoku; and the rare Tomoshige and Tomonori, smiths of few survivals through whom the phase's reach is gauged. Because signed early work is uncommon, the phase leans on *mumei* attributions read off forging and temper, several entered as *den* Ko-nyudo Kunimitsu. Provenance settles into shrine and institutional holding, the Hie Shrine and Kurokawa Institute tachi serving as the calibrating standards against which other early Kunifusa are judged, and the dated examples valued as documentary footing for the study of how Yamato workmanship took its northern form.
Kunifusa (國房) — Mainline · 1368-1375. Jūbi, Jūyō. Uda Kunifusa is the first-generation master of the Etchū Uda school, and one of the very few Ko-Uda smiths whose name survives in signed work. The published sources record him as a son of the Uda founder Ko-Nyūdō Kunimitsu, who carried the craft from Uda District in Yamato north to Etchū in the late Kamakura period, and they hold by tradition that Kunifusa himself studied under Etchū Norishige, naming the smith called Gō alongside as a model. The school's whole record is overwhelmingly mumei, ō-suriage, and appraised only to the group, so a signed Kunifusa is already a document; an early signed Kunifusa is rarer still. The appraisers anchor his shodai identity on two tachi designated Important Art Objects, one held by Hie Shrine and one by the Kurokawa Institute of Ancient Cultures, and judge further blades to him by the close calligraphic match of the inscription, in which, as one Jūyō entry puts it, the kuni enclosure of the character 国 is collapsed almost like a lattice. The earliest dated example of the name is a piece of Kōō 1 (1389).
His hand runs in two registers the Uda school never fused, and Kunifusa works both. The first is the Yamato root, seen most clearly in his tantō and wakizashi: hira-zukuri with mitsu-mune and a faint uchizori, several with a slightly elongated sun-nobi proportion, the kitae a well-packed itame or ko-itame with a flowing tendency. Over it he sets a chū-suguha mixed with ko-gunome and a shallow ko-notare, ashi entering, the nioi deep with ko-nie well adhered and at times somewhat coarse, and sunagashi and fine kinsuji running through. The bōshi runs straight into a ko-maru, often pointed in tendency with a deep turnback and hakikake. At the base he carves a devotional program of kurikara, su-ken, gomabashi and paired grooves, the kurikara on one tantō noted as unusual for the school. The published sources read these calmer signed pieces as his typical work, Ōei-dated or judged together with dated examples, sound in both ji and ha.
The jihada is the constant beneath both manners. Itame mixed with mokume and a flowing grain that tends to stand carries a well-adhering ji-nie, with chikei entering, and where the forging tightens into ko-itame a shirake-utsuri stands clearly. That tightness is in fact his personal tell within the school. Discussing the difference between the two principal Uda names, the published commentary observes that 「国宗がやや肌立ったものが多いのに対し国房には地がねのつんだものが多い」, that Kunimune is more often seen with a standing grain, whereas Kunifusa is frequently seen in a tightly forged jigane. On one mumei tachi judged to him, the commentary names the excellence of that forging as the deciding point, 「地がねの鍛錬がすぐれているところに国房と鑑すべき」, the quality of the steel itself returning the verdict to his hand.
The second register is the Sōshū-leaning manner, which the sources trace to his study under Norishige, and which shows in his bold Nanbokuchō tachi. These are wide in body with a thick kasane and a chū- or ō-kissaki, several keeping a high koshizori and funbari even where shortened, an imposing Nanbokuchō shape. Over a flowing itame with conspicuous chikei and ji-nie he tempers a notare or suguha base mixed with gunome, the nioi deep, the nie well adhered and at times coarse, with sunagashi running conspicuously and kinsuji entering, the bōshi midare-komi and turning back with hakikake. The published sources grant that such blades call the Sōshū tradition to mind through their prominent chikei and abundant nie, modeled on the earlier Etchū masters Norishige and Gō; the same entries caution that there are no purely Sōshū-construction works among them, and the verdict is held to Uda. The school's manner spans these poles, and the dating of any single Kunifusa blade is given as a span, late Nanbokuchō to early Muromachi, rather than to one hand, because the name continued through several generations.
What returns even his most Sōshū-looking blade to the northern provinces is the jigane, the feature the appraisal turns on. The steel tends to a dark, kanairo tone and grows kasu-datsu, hazy and standing, in places, a texture the published sources name as 「北国物特有の肌合」, the character distinctive to works of the north; the nioiguchi tends to sink rather than to glow, and the ha-nie carries rounded, compact nie that the same commentary calls 「つぶらな沸を交えている点などには宇多派の特徴」, a mark of the Uda school. His shirake-utsuri and the Yamato character of his calmer blades set him apart from the plainer northern smiths, while this darkened, dry-standing steel and the rounded ha-nie set him apart from the bright clear steel of true Sōshū. He stands beside Kunimune as a representative hand of the school, the tighter-forging brother by the appraisers' own account, the shodai whose lattice-broken kuni character secures the attributions.
For the collector Kunifusa is a rare early northern name rather than a market presence. Fujishiro grades him Jō-jō saku. He has no National Treasures and no Important Cultural Properties; his record runs instead through fourteen Jūyō blades and three prewar Jūyō Bijutsuhin, seventeen designated works in all, with the shodai represented by the two Important Art Object tachi held at Hie Shrine and at the Kurokawa Institute of Ancient Cultures. Of recorded whereabouts, a Jūyō tachi passed through the Kajimura collection of Osaka and another Important Art Object descends from Kurokawa Fukusaburō into the Kurokawa Institute. The published commentary calls one shodai tantō 「数少ない初代国房の作として資料的にも貴重」, valuable as documentary material, being among the few first-generation works. Most designated Uda, in public and long-private hands alike, is held rather than traded; a signed Kunifusa of the early dated period reaches the market only seldom, and a shodai example with the lattice-broken kuni character is a notable thing for a collector to encounter, a document of how a Yamato craft took root in the north.
Kunifusa (國房) — Mainline · 1381-1405. Jūbi. Smith of the Etchū Uda School.
Kunimitsu (國光) — Mainline · 1317-1319. Tokujū, Jūyō. Uda Kunimitsu (宇多国光), known as Ko-nyudo Kunimitsu (古入道国光), is traditionally regarded as the founder of the Uda school. According to accepted tradition, around the Bunpo era (1317–1319) he relocated from Uda District in Yamato Province to Utsu in Etchu Province, establishing a lineage that would flourish through subsequent generations. He is said to have had sons named Kunifusa and Kunimune, and subsequent smiths bearing the name Kunimitsu appear to span several generations from the late Kamakura into the Nanbokucho period. No definitively signed works by Ko-nyudo Kunimitsu himself are confirmed; however, extant tachi bearing the signature "Uda Kunimitsu" and datable to the late Kamakura period are reasonably attributed to his hand.
Blades attributed to Ko-nyudo Kunimitsu strongly display a Yamato-like character in both *jihada* and *hamon*. The forging typically shows tightly worked *ko-itame-hada*, at times with *masame-hada* mixed in toward the edge, well covered with *ji-nie* and intermingled with *chikei*. A whitish *utsuri* reminiscent of *shirake* may stand out in the *ji*. The *hamon* is characteristically *suguha*-based, occasionally exhibiting shallow *notare* with a slight admixture of small *gunome*; *ko-nie* adheres well, and *sunagashi* and *kinsuji* appear along the temper line. The *boshi* returns in *ko-maru* with *hakikake* at the tip. *Bo-hi* carved on both sides with *maru-dome* is a recurring feature.
Ko-nyudo Kunimitsu occupies a position of considerable importance as the progenitor of the Uda school, one of the principal forging traditions of Etchu Province. His work demonstrates the direct transmission of Yamato-den characteristics into a provincial setting during the late Kamakura period. Blades attributed to his hand that survive in *kenzen* condition constitute valuable reference material for understanding the formative period of the Uda tradition and the broader dissemination of Yamato forging methods into the northern provinces.
Kunimitsu (國光) — Mainline · 1362-1368. Jūyō. Kunimitsu is the founder of the Etchū Uda school, the monk-smith remembered as Ko-Nyūdō Kunimitsu, who is held to have come from Uda District in Yamato and to have settled at Uzu in Etchū around the Bunpō era of the late Kamakura period. The published sources treat his name as the hinge of the whole Ko-Uda attribution. Almost no securely signed work of the first generation survives, so his earliest pieces are read by their strong Yamato character and attributed to him as Ko-Nyūdō Kunimitsu, while a body of signed Uda Kunimitsu tachi and tantō reaching across the Nanbokuchō and into the early Muromachi period carries the same name into its later generations. A Kunimitsu blade may therefore date anywhere from the late Kamakura down to the Ōei era, and the published record cautions that the school's makers individuate little, so that the appraisal rests on era and school more than on a single hand.
His work is read in two manners with one diagnostic holding them together. The first is the Yamato root the school never lost. Over a wood-grain itame that flows and tends to stand he tempers a suguha or a quiet ko-midare, and into the habuchi he works the activity the published sources name as the school's own: a crossing kuichigai-ba, fine hotsure, crescent uchinoke, and a bōshi that runs straight into a small round ko-maru or sweeps off in hakikake. On the dated Genō tantō the NBTHK reads the construction itself as a confession of origin, observing that the large round, burned-off tip is the work of a Yamato-born hand (大丸風に焼詰めた帽子は大和出身を物語っている). It is the calmest, most archaic face of Kunimitsu, and the one the older mumei katana attributed to the founder most often wear.
The jigane is where the appraisal begins and ends. His is an itame, frequently mixed with mokume and a flowing nagare grain, the surface standing rather than lying flat, with ji-nie adhering and dark chikei entering. On his most characteristic blades the steel carries a blackish cast, and on one signed tantō it grows hazy and whitens as it stands. The published sources keep returning to this northern color as the thing that tells the school apart, reading a darkened jigane on one signed tachi as the distinct flavor of a northern-province blade (地がねが黒みをおびている点には北国物特有の持味を見せている). Over that jigane the hardening runs in nie rather than nioi, with sunagashi streaming through more than half his blades and kinsuji through a third, and a nioiguchi that tends to sink rather than to glow. The way the nie itself gathers along the habuchi is named on one katana as an Uda mark in its own right.
The second manner is the Sōshū-leaning one of the Nanbokuchō period. The published sources trace it to the Uda study under Etchū Norishige, with the smith called Gō set beside him as a model, and grant that many works of this period call the Sōshū tradition to mind while insisting that none are of purely Sōshū construction. Here the temper opens into a notare or a suguha base broken by ko-gunome and ko-midare, deep in nioi, the nie well applied, with yubashiri drifting and kinsuji and sunagashi running freely, and the bōshi turns into a midare-komi or points faintly at the tip. One signed Uda Kunimitsu tachi is read for exactly this division. The NBTHK records that among Ko-Uda there are two kinds, one finely forged with fine chikei and a bright steel, the other with standing grain and large chikei and a steel carrying a blackish cast, and assigns the two to different ancestries, holding that the former transmits the current of Yoshihiro and the latter that of Norishige (前者は義弘、後者は則重の流れを伝えている). That single sentence is the clearest statement the school leaves of how its Sōshū debt actually divides.
What keeps a nie-laden Kunimitsu blade from a Sōshū verdict is precisely the northern jigane and the sinking nioiguchi the second-manner pieces never lose. A blade dense with nie, kinsuji and sunagashi that would read as a high Sōshū hand at first sight is returned to Ko-Uda by its darkened, standing jigane and its subdued temper, and the published sources are explicit that the resemblance stops at construction. Against the true Sōshū masters the contrast runs through his own grounded traits rather than theirs: the Yamato hataraki he never sheds, the hakikake and kuichigai-ba and uchinoke, and the blackish steel that no Norishige or Gō blade shows. His sons Kunifusa and Kunimune carried the school forward into the Nanbokuchō period, Kunifusa drawing the Sōshū tradition into the Uda manner, and the Kunimitsu name itself was taken up by several later smiths, the published record placing one signed blade with the second generation and another with the Ōei-era Kunimitsu of the early fifteenth century.
The whole of his recorded work sits in the Juyo tier, where ten blades are held, a mix of ō-suriage mumei katana attributed to the founder as Ko-Nyūdō Kunimitsu and signed Uda Kunimitsu tachi and tantō of the later generations. He has no National Treasures and no Important Cultural Properties, and the published record preserves no daimyō provenance or museum holding for his blades, so the honest account is of a school name carried by Juyo-ranked work rather than of a roll-call of famous swords. The NBTHK singles out the best of these for the soundness of both ji and ha, calling one darkened katana a piece of restrained, austere quality (渋味のある優品), and naming the nie along its habuchi as the Uda tell (刃縁の沸のつき方に宇多の特色がみられる). A Kunimitsu blade is not beyond reach in the way a National Treasure is, since the body that survives is Juyo and from time to time one of the signed later-generation pieces or an attributed mumei katana changes hands, but the founder's own securely first-generation work is among the rarer things a collector of the northern schools could hope to encounter, and most of what exists is held rather than traded. For a student of how the Yamato and Sōshū currents met in the northern provinces, his blades are the place where that meeting can actually be seen.
Tomonori (友則) — Mainline · 1390-1394. Jūyō. Four signed blades carry the name Tomonori (友則) into the present, each cut with a thick two-character mei toward the mune of an ubu or modestly shortened tang, and on the earliest the published sources remark that a signed, ubu-nakago tachi of this kind is a rare survival for the school. Tomonori is a smith of the Etchu Uda school, working from the late Nanbokucho into the early Muromachi. His line began when the monk-smith Ko-Nyudo Kunimitsu came north from Uda District in Yamato Province and settled in Etchu in the late Kamakura, carrying a Yamato-derived manner into the northern provinces; through the Nanbokucho the school sent out smiths such as Kunifusa, Kunimune and Kunitsugu, who re-used its names down the generations, and it flourished into the late Muromachi. The term Ko-Uda is reserved, within that descent, for the work of the late Kamakura through the Nanbokucho, and it is among the Ko-Uda smiths that the published record places these tachi. The reference works list five Uda smiths who used the name Tomonori, the oldest active around Meitoku and the line continuing to the Eisho, and the surviving signed blades are appraised as the earliest, the Tomonori of around Meitoku.
The published record reads his hand two ways, and the two manners are the heart of recognizing him. One is quiet. Over a tight itame that flows a little and stands with a whitish cast he tempers a narrow or medium suguha, mixing in ko-gunome and kuichigai-ba, ashi and yo entering and the nioiguchi drawn tight and bright, nioi predominating and the habuchi frayed into hotsure formed in fine nie. The disorder is kept small, the boshi runs straight and rounds into ko-maru with a slight turn-back, and on the late-Nanbokucho tachi the published sources judge that this register 'displays one characteristic style of this smith, is of good workmanship, and both ji and ha are sound.' The other manner is loud. The same itame, mixed now with mokume, stands more openly and takes a darkish tone, ji-nie adhering well and fine chikei entering, with yubashiri and tobiyaki breaking into the ji; over it a wider suguha or a shallow notare breaks into gunome and togariba, the tempered width widening in the upper half, coarse nie spilling into the ji and uneven nie in patches, until abundant tobiyaki and muneyaki rise to a hitatsura and the boshi is tempered deep into a flame.
The jigane is the constant beneath both hands. It is itame throughout, on the quieter tachi tight and flowing with a slight admixture of mokume and a whitish surface, on the nie-laden blades more open and standing, mixed with mokume, set with ji-nie and threaded with fine chikei, and darkish in tone. That dark steel is the feature the published sources lean on to fix his province, the kodachi read as associated with the smiths of the northern provinces by its dark color. The activity in the hamon tells the older half of the same story. The plentiful nie, the sunagashi running through the temper, the kinsuji and the brushed hakikake at the tip are read as a Yamato character carried down from Kunimitsu's migration: 'in both ji and ha the nie is plentiful, and from the frequent sunagashi and the abundant hakikake a Yamato disposition is evident,' the published sources say of the kodachi, before turning to the dark steel that ties the same blade to the north. The two readings, Yamato in the activity and Etchu in the color, sit together in a single piece and are the kantei the institution draws.
His four blades fall cleanly into those two registers, and the split runs partly with form and date. The quiet suguha hand carries the two tachi the records read as the earlier work, one a slender blade with deep koshizori and a small kissaki in the old fashion, the other appraised as the Meitoku-era smith, both tight in the ji and restrained in the ha. The nie-laden hand carries the kodachi and the latest, widest tachi, where the temper departs the quiet base for gunome, togariba and a hitatsura; on that broadest tachi the mihaba is wide with a pronounced taper, the kasane thick and the curvature high, and the published sources find in the deep flame boshi taken with the dark standing ji and the all-over temper that 'the characteristics of northern-province work are markedly manifest.' The dating is argued against the old directories rather than assumed: an entry grouping Tomonori with the Etchu Norishige line around the Kenmu era is held not to accord with the earliest tachi, and another placing him in a Kaga-resident second-generation Uda line is judged too late, so that each blade is fixed instead by its own ji and ha to the Nanbokucho and early Muromachi.
Within the school he is a known quantity rather than a founder or a head, and the published record is careful about how much can be built on him. His own traits lead the appraisal: the standing dark itame, the coarse nie spilling into the ji, the tobiyaki and muneyaki rising to a hitatsura and the flame boshi mark his nie-laden work, while the tight whitish suguha with ko-gunome and a bright nioiguchi marks the quiet half, and it is the presence or absence of the streaming nie that sorts one of his blades into one register or the other. No successor line is drawn through him; with only four signed blades the corpus is too thin to extend the school forward in his name. What the sources do say is that other works of his have likewise reached Important Sword rank, and that among the Uda group, whose extant works are not numerous, 'he was a smith of high technical ability,' a judgment placing him above the run of the school without making him its head.
His whole designated record is four Juyo tachi and kodachi, with no National Treasure or Important Cultural Property among them and no piece carrying a recorded daimyo provenance, so the connoisseurship rests on the blades themselves rather than on a roll of famous holders. That four signed pieces survive at all is the point the school's students return to, signed Uda work being uncommon, and the latest tachi is valued expressly as documentary material, the published sources calling it 'a fine resource for the study of this smith' and noting that it appears in the Kozan oshigata before a fourth mekugi-ana was bored, with the tang annotated 'Etchu work' (越中物). For a collector this is a name met through the Juyo tier, not held in a museum: the blades are kept, not traded, and one reaches the market only from time to time and with patience, but a signed Tomonori (友則) when it appears carries the rarer of the two things the school offers, a name surviving in the smith's own hand and a workmanship the institution ranks among the most able in the Uda line.

Phase 2 · Uda (宇多) · 1390 – 1596
Where Ko-Uda closes with the Nanbokuchō generations, the chapter that follows opens in early Muromachi and runs to the end of the period. The setsumei draw the boundary plainly: works that descend no later than Nanbokuchō are called Ko-Uda, while everything thereafter is referred to simply as Uda. This later phase is the long Muromachi continuation in Etchū, where the Kuni-named line that began with Ko-Nyūdō Kunimitsu of Uda District in Yamato extends across successive generations sharing single names. Kunihisa, read by the *meikan* as son of Kunifusa and active from the Ōei era, runs through several generations down to the close of Muromachi; Kunimune carries from Nanbokuchō into Muromachi with dated pieces around Bunmei; and the later registers add Kuninaga, Kuniyoshi, Hirakuni, Sanekuni, Kunikiyo, Tomohisa, and Kunitsugu, names the sources place from Eikyō through Tenshō. Because individuals individuate little, a signed blade of this phase is appraised as the manner of its dated moment rather than the hand of one smith.
The steel of the later phase keeps the school's northern foundation while standardizing its expression. The setsumei describe *itame* mixed with *mokume*, the grain overall standing (*hada-dachi*) and tending to flow (*nagare*), with *ji-nie* adhering and *chikei* entering; the *jigane* leans blackish, and a *shirake-utsuri* stands distinctly in the *ji*, sometimes with *ji-madara* mottling. Over this the temper most often opens as a *suguha*-based or *chū-suguha* line into which *ko-gunome* runs continuously from base to point, *ashi* and *yō* entering, *ko-nie* adhering along a bright *nioiguchi*, with *sunagashi* and occasional *kinsuji*. A second, more agitated face mixes *gunome*, *ko-notare* and pointed *togariba* with thick *nie*, *yubashiri* and *tobiyaki* that on a Kuninaga *wakizashi* tend toward *hitatsura*. Against the earlier Ko-Uda this reads more regularized: where the early generations stayed close to their Yamato and Sōshū models with archaic *ji-ha*, the later hands settle into the elongated Ōei *tantō* form (broad for its width, with *uchizori*) and, in the *katana*, the wide *sun-nobi* sugata of advancing Muromachi. The Kunitsugu *katana* shows this drift toward coarseness directly, its *itame* standing and rough, the *nie* uneven and the temper darkening at the edge.
To separate later Uda from Ko-Uda is to read the steel before the temper. The whitish, standing *jigane* with its blackish cast and *shirake-utsuri* returns a blade to this phase even when a *nie*-laden *midare* recalls Sōshū at first glance, and a tightly forged *ko-itame* may, as with the better Kunihisa pieces, approach Rai Kunimitsu or Rai Kunitsugu before the dark northern grain brings it home. Distinctive markers recur across the named smiths: the *bōshi* that becomes pointed and is tempered down with a long *kaeri*, the flaring (*susodoshii*) *nakago-jiri*, somewhat coarse rounded *nie* mixed within the *ha*, and the particular shaping of the character *kuni* in the signature. Dated and signed pieces anchor the chronology, from a Kunihisa *tantō* of Ōei 7 to a Kunimune *wakizashi* placed around Bunmei and Hirakuni and Sanekuni works set near Tenbun. Provenance for the phase tends toward settled holding, with examples resting in the Imperial Collection rather than circulating.
Kunimune (國宗) — Mainline · 1429-1479. Jūyō. One signed Uda Kunimune katana carries a Bunmei 11 date of 1479 cut on the reverse of an essentially ubu tang, and that single dated blade fixes the smith his name records best: a maker of the Etchū Uda school working in the middle of the Muromachi period. The published sources hold the first-generation Kunimune to be a son of Ko-Nyūdō Kunimitsu, the founder who carried the line north from Uda District in Yamato to Etchū around the Bunpō era at the close of the Kamakura period, and the younger brother of Kunifusa. The name then continued through several generations from the Nanbokuchō period down through the late Muromachi and on into the shintō era, so that a signed Uda Kunimune is read less as one hand than as the school manner of a period. Because the school's smiths individuate little, the published record appraises the surviving signed work by shape and the character of ji and ha rather than by an individual signature, placing the dated and dateable pieces around the Bunmei era when the Uda school flourished.
His work is read in two faces over one jigane. The quieter is the Yamato root the school never lost, seen most plainly on a signed ubu tantō in hira-zukuri with customary uchizori and a gomabashi carving. There the kitae is a ko-itame with masame-hada mixing in toward the edge, ji-nie adhering and chikei entering, and over it the temper is a chū-suguha with the nioiguchi somewhat tight, ko-nie adhering, the boundary near the hamachi tending toward yakikomi, the bōshi running straight into a ko-maru. The published sources read this register as a clear statement of origin, observing that the forging in which flowing masame mingles with the grain vividly expresses the Yamato tradition (流れ柾が交じる鍛えに大和伝をよく表わしており) and that the blade as a whole displays the distinctive character of Uda work (総体に宇多物の特色をよく示している).
The more active face is the school's Muromachi midare, the manner the published sources date to around the Bunmei era from the shape and the character of ji and ha. Over an itame mixed at times with mokume, flowing and standing rather than lying flat, the temper is a gunome broken by ko-notare, ko-gunome, chōji-like elements and a pointed tendency, with ashi and yō entering well, ko-nie adhering and sunagashi running frequently. Here and there slight yubashiri and nijūba appear, and on the widest blade the yakihaba broadens until from the middle upward it reaches the shinogi and around the monouchi shows an overall hitatsura-like temper, the bōshi a midare-komi vigorous in nie and carrying tobiyaki, tempered down long into the tang. On the calmer pieces that turnback becomes ko-maru-like and shows hakikake. The published sources call one such wakizashi a fine example in which the nioiguchi is bright and ko-nie adheres well, demonstrating not only the maker's style but the distinctive character of the whole Uda school (匂口が明るく小沸がよくついた作柄を見せており、同工のみならず同派の特色をよく示した佳品).
Under both faces lies the one jigane the appraisal turns on. His is an itame that flows and tends to stand, masame mixing in toward the edge, ji-nie adhering and chikei intermingling, and it is this northern, Yamato-derived steel that returns an Uda blade to its school when the temper alone might recall a Yamashiro or Sōshū hand. The carving on his blades extends the same Yamato temperament: the dated wakizashi bears long bonji set one above another with a suken below on the omote, and three bonji with a koshihi in kaki-nagashi on the ura, work the published sources judge splendid. The signatures are a four-character mei cut with a fine or somewhat thick chisel below the mekugi-ana, and the tangs are ubu or only very slightly machi-okuri, the feature that makes these blades documents as much as swords.
What sets his work apart is read through his own grounded traits rather than through any borrowed comparison. The flowing, standing itame with its mixed masame, the frequent sunagashi, and the gunome carrying pointed elements and ko-notare are the marks the published record names as the Uda character, against which his single suguha tantō stands as the quiet Yamato counterpart. The published sources are explicit that this is a school appraisal: they record the founder's migration from Yamato to Etchū, the descent of Kunimune from Kunimitsu and his place beside Kunifusa, and the continuation of the name through several generations, and they assign the dated and dateable signed pieces to the Bunmei era on the evidence of shape and workmanship. Across the corpus the resemblance to the Sōshū-leaning Uda manner of the Nanbokuchō generations is present in the nie activity, while the brightness of the nioiguchi and the standing northern jigane keep the verdict with the Uda school.
The whole of Kunimune's official record is held in the Juyo tier, where four signed blades survive across tachi, katana, wakizashi and tantō, with Fujishiro rating him Jō-saku and the Tōkō Taikan placing him at 300. He has no National Treasures and no Important Cultural Properties, so the honest account is of a school name carried by Juyo-ranked work and by its value as research material rather than of a roll-call of famous swords. The published sources single out the dated tachi for exactly this, noting that ubu signed tachi of this period are few and that the blade is therefore valuable source material (この時代の生ぶ茎、有銘の太刀は少く、好資料でもある), and they read the dated katana as an important document for research into the smith and the school, sound in both ji and ha. Two of his blades are recorded in the Imperial Collection, the most distinguished provenance his work carries. For a private collector the signed Uda Kunimune pieces in the Juyo tier come to market only from time to time and with patience, a maker whose blades reward the student of how the Yamato tradition was carried into the northern provinces more than the chaser of a celebrated name.
Moriyoshi (守吉) — Mainline · 1394-1428. Jūbun. Smith of the Etchū Uda School.
Kunihisa (國久) — Mainline · 1394-1428. Jūyō. Uda Kunihisa is the Ōei-era hand of the Etchū Uda school, the line the reference registers carry from Ko-Nyūdō Kunimitsu, the monk-smith who migrated from Uda District in Yamato to Etchū at the close of the Kamakura period and whose name flourished into the late Muromachi. The *Meikan* records Kunihisa as the son of Kunifusa, in another reading the son of Kunimune, gives him the studio name Uemon Saburō, and dates the first generation to Ōei, the same name then continuing for several generations through the Hōtoku and Bunmei eras toward the end of Muromachi. Of that long line he is the one hand the published sources treat as typical of the school and read against its founder. His work survives signed, a thing rare among Uda smiths, and the body of it is the long early-Muromachi *tantō*, broad for its length and with little or no curvature, that the school favored over the *tachi* and *uchigatana* it seldom made, joined by a few *wakizashi*, a *tachi*, and even a great spear. One of his blades carries a date of Ōei 7, which the judges hold to predate even the recorded examples of the line, calling it the earliest of all and "a valuable document, and besides of fine make" (資料的にも貴重であり、かつ出来が優れている).
Kunihisa is read first off the steel, for his temper is the school idiom and it is the *jigane* that carries him. On the calmer blades he forges an *itame* that runs and stands, flowing slightly toward *masame*, the steel turning whitish so that a *shirake-utsuri* or a faint *bō-utsuri* stands in the *ji*, with *ji-nie* throughout. Over it he tempers a *chū-suguha* or a *suguha*-toned line, opening shallowly into *notare* with pointed *gunome* and *ko-gunome* mixed in, *ashi* entering, the *nioiguchi* drawn tight, *ko-nie* well adhered, and along the *habuchi* the Yamato activity of *kuichigai-ba* and *hotsure* that names the school's old province. The published sources call exactly this combination, a whitish standing *itame* under a tight *chū-suguha*, the very type of the Uda hand, and on one signed *tantō* of just this make they write that "this is precisely that type, and the make is good" (まさにその典型であり、出来がよい). Through the *ha* run *sunagashi*, which lie on nearly every surviving blade, and *kinsuji* through most, the *nie-deki* activity that holds steady whether the temper is calm or roused.
The second manner the sources draw from him is the Sōshū-leaning one, which they trace to Kunifusa's study under Etchū Norishige, granting that much Uda work of this period calls the Sōshū tradition to mind while holding that none is of pure Sōshū construction. On the dated Ōei 7 *tantō* the *jigane* is an *itame* with *moku* and *chikei* entering, the temper a shallow *notare* mixed with *gunome*, *ko-nie* applied and *kinsuji* running, and the judges read it plainly as Sōshū-leaning. In this register the body broadens, the *nie* thickens and grows at times coarse, *yubashiri*, *kinsuji* and *sunagashi* run more freely, and on the finest blades a round, luminous *nie* scatters through the *yakiba*. The *bōshi* turns *midare-komi*, the tip pointed or pushed up, the turnback long and at times deep. A nie-laden Kunihisa blade reads as Sōshū at first glance, and the published sources return it to Uda by the steel, the dark, whitish *jigane* and the *nioiguchi* that holds rather than glows.
Beyond the school formulas the sources name what is Kunihisa's own, and it is a quality of *jigane* rather than a new shape. His finest *tantō* and *wakizashi* are a *ko-itame* so well forged and compacted that the steel turns refined and bright, *ji-nie* laid on densely and at times dust-fine as *ji-nie mijin*, a *jigane* darkish and whitish with a faint *utsuri*. Through the *yakiba* runs the round, luminous *nie* the school calls its own, the *ha* and *ji* alike clear, and on one such blade the judges find "in the well-forged, refined surface, Kunihisa's individuality can be seen" (国久の個性が着て取れる), naming the same piece "an outstanding work among the finest" (屈指の優品である). The Uda *jigane*, they note in passing, runs to two kinds, one that stands and one that compacts and gathers abundant *ji-nie*; Kunihisa is read on the side that gathers and refines. His blades are otherwise plain in their fittings, a *bō-hi* or *koshi-hi* run out on the spear and the *tantō*, *gomabashi* and a *suken* carved on others, the carving kept simple beneath the working of the steel.
What distinguishes Kunihisa within the late Uda line is the brightness of that refined steel, which the sources read toward Yamashiro rather than toward his own school's duller hands. On a *tachi* whose construction stands high in the *shinogi* and runs to a *ko-gunome midare* with *hotsure* and *sunagashi* and a *yakizume bōshi*, they call the manner Yamato in temperament and "a work showing the characteristics of Uda" (宇多物の特色を示した一口である). On his best *wakizashi* and *tantō*, where the *ko-itame* tightens and the bright round *nie* gathers, they go further, writing that the blade "calls Rai Kunimitsu and Kunitsugu to mind at a glance, a fine work of Kunihisa" (一見来国光・国次らを髣髴とさせる、国久の秀作である), and of another that it is "of a make all but mistakable for Rai Kunimitsu or Kunitsugu" (来国光や国次に紛れんばかりの出来映え). His own *shirake-utsuri* and standing *itame* set him apart from the Yamashiro hands he approaches, and his refinement sets him apart from the plainer Uda smiths around him; the verdict in every case rests on the steel, not on the temper.
For the collector Kunihisa is a soundly recorded provincial name rather than a famous one. He has no National Treasures and no Important Cultural Properties; his record runs entirely through the Juyo rank, where ten of his blades are held, the *Tōkō Taikan* rating him at four hundred and the *Fujishiro* registers placing him at *chū-jō saku*, a competent middle-upper hand. Of his blades whose present whereabouts are recorded, several rest with shrines and a museum, among them Yasukuni Jinja, the Kunōzan Tōshōgū and the Suiboku Museum, the kind of long, settled holding that keeps most designated work off the market. With ten Juyo blades on record and most of them held rather than traded, a signed Uda Kunihisa comes to a private collector only from time to time, and with patience; when one does, it is a clear window onto how the northern Uda forged at its Ōei height, the moment the school's steel ran bright enough to be taken, for an instant, for Rai.

Kunitsugu (國次) — Mainline · 1469-1487. Jūyō. The Uda school traces its origin to the late Kamakura period, when the monk Kunimitsu migrated from Uda District in Yamato Province to Etchu Province. Kunitsugu is a name borne by several generations within this lineage; reference works record the first as a brother of Kunifusa, active around the Enbun era (1356-1361), and the line continued through at least the Tenbun era (1532-1555). The school flourished particularly during the Muromachi period, producing a substantial body of work across long swords, tanto, and yari.
The Kunitsugu setsumei reveal a consistent Uda character: an *itame-hada* that tends toward standing grain (*hada-dachi*), sometimes mixed with *masame* or *mokume*, often with a slightly blackish tone to the *ji*. The tempering favors *ko-notare* mixed with *gunome* and *ko-gunome*, laden with clustered *nie*, frequent *sunagashi*, and intermingled *kinsuji*. A Nanbokucho-period tachi (Juyo, 23rd Session) displays "an *itame* forging with a tendency toward *masame*" and "a whitish *utsuri*," with *ko-gunome* mixed with *ko-midare* showing "abundant activities -- *ashi* and *yo*, well-formed *nie*, and *sunagashi*." A tanto of the Oei to Shocho era (Juyo, 15th Session) presents "the typical manner of Uda work from that time," with deep *nioiguchi* and thick *nie*.
The school's designated corpus includes a yari dated Bunmei 17 (1485) -- a rare signed spear predating the common Muromachi-period proliferation of such weapons -- which the NBTHK deems "valuable as important material for research into the Uda school." Across blade forms and periods, the Uda Kunitsugu works maintain a robust, *nie*-laden aesthetic tempered by the provincial vigor of their Etchu origin.

The Etchū Uda School
Carried from Yamato to the northern province of Etchū, the Uda smiths kept a masame-laced tradition through two phases — the founding Ko-Uda generations of the Nanbokuchō, and the long Uda line that worked the forges into the late Muromachi.

The Etchū Uda School (宇多) Lineage
The The Etchū Uda School (宇多), active 1310–1596 in Etchū Province across 48 documented smiths: 0 Kokuhō (National Treasures), 1 Jūbun, 4 Jūbi, 1 Tokubetsu Jūyō, 120 Jūyō.
Phase 1 · Ko-Uda (古宇多) · 1310 – 1394
Ko-Uda (古宇多) names the founding stratum of the Uda school, the work that does not descend later than the Nanbokucho period and so stands before the long Muromachi continuation that the same studio names would carry. The setsumei place the origin in Yamato: around the Bunpo era at the close of Kamakura, the monk-smith Ko-nyudo Kunimitsu left Uda District in Yamato and settled at Utsu in Etchu, and from him the lineage took root. His sons Kunifusa and Kunimune are recorded, and across the *Juyo* and *Jubi* explanations the active founding hands are listed together as Kunifusa, Kunimune, and Kunitsugu, the generations that worked through the Nanbokucho period before the name-bearing successions ran down into late Muromachi. A signed Ko-nyudo Kunimitsu is hard to fix among several smiths who used the name; the *Tokuju* tachi is read as the founder precisely because it shows the most archaic character of the surviving examples, earlier even than the Kunifusa pieces taken for Nanbokucho.
The early steel is the school read at its source. The forging is *itame* mixed with *mokume* and running *nagare-hada* that tends to stand (*hada-dachi*), *ji-nie* adhering with *chikei*, and over it a whitish *shirake-utsuri* or, on the founder's own work, a *nie-utsuri*; the *jigane* carries a blackish, golden-toned cast that the explanations call a northern-province feeling. The temper sits in narrow to *chu-suguha*, opening into *ko-notare*, *ko-gunome*, *ko-midare*, and *togariba*, with *ko-ashi* and *yo* and *ko-nie* well set; along the *habuchi* the Yamato signature of *hotsure* and *kuichigai-ba* appears, while *kinsuji* and *sunagashi* run through. Against the later Uda generations, the Ko-Uda face is the purer one. The *Tokuju* founder is appraised as workmanship entirely like Yamato; the Hie Shrine and Kurokawa tachi by the shodai Kunifusa hold a tight, clear *nioiguchi* and a bright forging, and the *nie* in the best stands strong and rounded where the later hands run coarser and more provincial. A Soshu lean exists, traced to the study of Norishige and Go, yet in this phase the steel and *nioiguchi* keep returning the blade to Yamato roots rather than dissolving into them.
To *kantei* a Ko-Uda blade is to catch the standing, whitish *jigane* with its *masame* tendency and *utsuri* beneath a *suguha* that might otherwise recall Yamashiro, and to bring a *nie*-rich, *chikei*-laden example home from Soshu by the dark steel and the subdued (*shizumi*) *nioiguchi*. The named early hands recur across the corpus: the shodai Kunifusa, fixed against dated pieces no earlier than Koo 1 (1389) and the calligraphy of the lattice-broken 国; the signed Ko-Uda Kunimitsu and Ko-Uda Tomonori of around Meitoku; and the rare Tomoshige and Tomonori, smiths of few survivals through whom the phase's reach is gauged. Because signed early work is uncommon, the phase leans on *mumei* attributions read off forging and temper, several entered as *den* Ko-nyudo Kunimitsu. Provenance settles into shrine and institutional holding, the Hie Shrine and Kurokawa Institute tachi serving as the calibrating standards against which other early Kunifusa are judged, and the dated examples valued as documentary footing for the study of how Yamato workmanship took its northern form.
Kunifusa (國房) — Mainline · 1368-1375. Jūbi, Jūyō. Uda Kunifusa is the first-generation master of the Etchū Uda school, and one of the very few Ko-Uda smiths whose name survives in signed work. The published sources record him as a son of the Uda founder Ko-Nyūdō Kunimitsu, who carried the craft from Uda District in Yamato north to Etchū in the late Kamakura period, and they hold by tradition that Kunifusa himself studied under Etchū Norishige, naming the smith called Gō alongside as a model. The school's whole record is overwhelmingly mumei, ō-suriage, and appraised only to the group, so a signed Kunifusa is already a document; an early signed Kunifusa is rarer still. The appraisers anchor his shodai identity on two tachi designated Important Art Objects, one held by Hie Shrine and one by the Kurokawa Institute of Ancient Cultures, and judge further blades to him by the close calligraphic match of the inscription, in which, as one Jūyō entry puts it, the kuni enclosure of the character 国 is collapsed almost like a lattice. The earliest dated example of the name is a piece of Kōō 1 (1389).
His hand runs in two registers the Uda school never fused, and Kunifusa works both. The first is the Yamato root, seen most clearly in his tantō and wakizashi: hira-zukuri with mitsu-mune and a faint uchizori, several with a slightly elongated sun-nobi proportion, the kitae a well-packed itame or ko-itame with a flowing tendency. Over it he sets a chū-suguha mixed with ko-gunome and a shallow ko-notare, ashi entering, the nioi deep with ko-nie well adhered and at times somewhat coarse, and sunagashi and fine kinsuji running through. The bōshi runs straight into a ko-maru, often pointed in tendency with a deep turnback and hakikake. At the base he carves a devotional program of kurikara, su-ken, gomabashi and paired grooves, the kurikara on one tantō noted as unusual for the school. The published sources read these calmer signed pieces as his typical work, Ōei-dated or judged together with dated examples, sound in both ji and ha.
The jihada is the constant beneath both manners. Itame mixed with mokume and a flowing grain that tends to stand carries a well-adhering ji-nie, with chikei entering, and where the forging tightens into ko-itame a shirake-utsuri stands clearly. That tightness is in fact his personal tell within the school. Discussing the difference between the two principal Uda names, the published commentary observes that 「国宗がやや肌立ったものが多いのに対し国房には地がねのつんだものが多い」, that Kunimune is more often seen with a standing grain, whereas Kunifusa is frequently seen in a tightly forged jigane. On one mumei tachi judged to him, the commentary names the excellence of that forging as the deciding point, 「地がねの鍛錬がすぐれているところに国房と鑑すべき」, the quality of the steel itself returning the verdict to his hand.
The second register is the Sōshū-leaning manner, which the sources trace to his study under Norishige, and which shows in his bold Nanbokuchō tachi. These are wide in body with a thick kasane and a chū- or ō-kissaki, several keeping a high koshizori and funbari even where shortened, an imposing Nanbokuchō shape. Over a flowing itame with conspicuous chikei and ji-nie he tempers a notare or suguha base mixed with gunome, the nioi deep, the nie well adhered and at times coarse, with sunagashi running conspicuously and kinsuji entering, the bōshi midare-komi and turning back with hakikake. The published sources grant that such blades call the Sōshū tradition to mind through their prominent chikei and abundant nie, modeled on the earlier Etchū masters Norishige and Gō; the same entries caution that there are no purely Sōshū-construction works among them, and the verdict is held to Uda. The school's manner spans these poles, and the dating of any single Kunifusa blade is given as a span, late Nanbokuchō to early Muromachi, rather than to one hand, because the name continued through several generations.
What returns even his most Sōshū-looking blade to the northern provinces is the jigane, the feature the appraisal turns on. The steel tends to a dark, kanairo tone and grows kasu-datsu, hazy and standing, in places, a texture the published sources name as 「北国物特有の肌合」, the character distinctive to works of the north; the nioiguchi tends to sink rather than to glow, and the ha-nie carries rounded, compact nie that the same commentary calls 「つぶらな沸を交えている点などには宇多派の特徴」, a mark of the Uda school. His shirake-utsuri and the Yamato character of his calmer blades set him apart from the plainer northern smiths, while this darkened, dry-standing steel and the rounded ha-nie set him apart from the bright clear steel of true Sōshū. He stands beside Kunimune as a representative hand of the school, the tighter-forging brother by the appraisers' own account, the shodai whose lattice-broken kuni character secures the attributions.
For the collector Kunifusa is a rare early northern name rather than a market presence. Fujishiro grades him Jō-jō saku. He has no National Treasures and no Important Cultural Properties; his record runs instead through fourteen Jūyō blades and three prewar Jūyō Bijutsuhin, seventeen designated works in all, with the shodai represented by the two Important Art Object tachi held at Hie Shrine and at the Kurokawa Institute of Ancient Cultures. Of recorded whereabouts, a Jūyō tachi passed through the Kajimura collection of Osaka and another Important Art Object descends from Kurokawa Fukusaburō into the Kurokawa Institute. The published commentary calls one shodai tantō 「数少ない初代国房の作として資料的にも貴重」, valuable as documentary material, being among the few first-generation works. Most designated Uda, in public and long-private hands alike, is held rather than traded; a signed Kunifusa of the early dated period reaches the market only seldom, and a shodai example with the lattice-broken kuni character is a notable thing for a collector to encounter, a document of how a Yamato craft took root in the north.
Kunifusa (國房) — Mainline · 1381-1405. Jūbi. Smith of the Etchū Uda School.
Kunimitsu (國光) — Mainline · 1317-1319. Tokujū, Jūyō. Uda Kunimitsu (宇多国光), known as Ko-nyudo Kunimitsu (古入道国光), is traditionally regarded as the founder of the Uda school. According to accepted tradition, around the Bunpo era (1317–1319) he relocated from Uda District in Yamato Province to Utsu in Etchu Province, establishing a lineage that would flourish through subsequent generations. He is said to have had sons named Kunifusa and Kunimune, and subsequent smiths bearing the name Kunimitsu appear to span several generations from the late Kamakura into the Nanbokucho period. No definitively signed works by Ko-nyudo Kunimitsu himself are confirmed; however, extant tachi bearing the signature "Uda Kunimitsu" and datable to the late Kamakura period are reasonably attributed to his hand.
Blades attributed to Ko-nyudo Kunimitsu strongly display a Yamato-like character in both *jihada* and *hamon*. The forging typically shows tightly worked *ko-itame-hada*, at times with *masame-hada* mixed in toward the edge, well covered with *ji-nie* and intermingled with *chikei*. A whitish *utsuri* reminiscent of *shirake* may stand out in the *ji*. The *hamon* is characteristically *suguha*-based, occasionally exhibiting shallow *notare* with a slight admixture of small *gunome*; *ko-nie* adheres well, and *sunagashi* and *kinsuji* appear along the temper line. The *boshi* returns in *ko-maru* with *hakikake* at the tip. *Bo-hi* carved on both sides with *maru-dome* is a recurring feature.
Ko-nyudo Kunimitsu occupies a position of considerable importance as the progenitor of the Uda school, one of the principal forging traditions of Etchu Province. His work demonstrates the direct transmission of Yamato-den characteristics into a provincial setting during the late Kamakura period. Blades attributed to his hand that survive in *kenzen* condition constitute valuable reference material for understanding the formative period of the Uda tradition and the broader dissemination of Yamato forging methods into the northern provinces.
Kunimitsu (國光) — Mainline · 1362-1368. Jūyō. Kunimitsu is the founder of the Etchū Uda school, the monk-smith remembered as Ko-Nyūdō Kunimitsu, who is held to have come from Uda District in Yamato and to have settled at Uzu in Etchū around the Bunpō era of the late Kamakura period. The published sources treat his name as the hinge of the whole Ko-Uda attribution. Almost no securely signed work of the first generation survives, so his earliest pieces are read by their strong Yamato character and attributed to him as Ko-Nyūdō Kunimitsu, while a body of signed Uda Kunimitsu tachi and tantō reaching across the Nanbokuchō and into the early Muromachi period carries the same name into its later generations. A Kunimitsu blade may therefore date anywhere from the late Kamakura down to the Ōei era, and the published record cautions that the school's makers individuate little, so that the appraisal rests on era and school more than on a single hand.
His work is read in two manners with one diagnostic holding them together. The first is the Yamato root the school never lost. Over a wood-grain itame that flows and tends to stand he tempers a suguha or a quiet ko-midare, and into the habuchi he works the activity the published sources name as the school's own: a crossing kuichigai-ba, fine hotsure, crescent uchinoke, and a bōshi that runs straight into a small round ko-maru or sweeps off in hakikake. On the dated Genō tantō the NBTHK reads the construction itself as a confession of origin, observing that the large round, burned-off tip is the work of a Yamato-born hand (大丸風に焼詰めた帽子は大和出身を物語っている). It is the calmest, most archaic face of Kunimitsu, and the one the older mumei katana attributed to the founder most often wear.
The jigane is where the appraisal begins and ends. His is an itame, frequently mixed with mokume and a flowing nagare grain, the surface standing rather than lying flat, with ji-nie adhering and dark chikei entering. On his most characteristic blades the steel carries a blackish cast, and on one signed tantō it grows hazy and whitens as it stands. The published sources keep returning to this northern color as the thing that tells the school apart, reading a darkened jigane on one signed tachi as the distinct flavor of a northern-province blade (地がねが黒みをおびている点には北国物特有の持味を見せている). Over that jigane the hardening runs in nie rather than nioi, with sunagashi streaming through more than half his blades and kinsuji through a third, and a nioiguchi that tends to sink rather than to glow. The way the nie itself gathers along the habuchi is named on one katana as an Uda mark in its own right.
The second manner is the Sōshū-leaning one of the Nanbokuchō period. The published sources trace it to the Uda study under Etchū Norishige, with the smith called Gō set beside him as a model, and grant that many works of this period call the Sōshū tradition to mind while insisting that none are of purely Sōshū construction. Here the temper opens into a notare or a suguha base broken by ko-gunome and ko-midare, deep in nioi, the nie well applied, with yubashiri drifting and kinsuji and sunagashi running freely, and the bōshi turns into a midare-komi or points faintly at the tip. One signed Uda Kunimitsu tachi is read for exactly this division. The NBTHK records that among Ko-Uda there are two kinds, one finely forged with fine chikei and a bright steel, the other with standing grain and large chikei and a steel carrying a blackish cast, and assigns the two to different ancestries, holding that the former transmits the current of Yoshihiro and the latter that of Norishige (前者は義弘、後者は則重の流れを伝えている). That single sentence is the clearest statement the school leaves of how its Sōshū debt actually divides.
What keeps a nie-laden Kunimitsu blade from a Sōshū verdict is precisely the northern jigane and the sinking nioiguchi the second-manner pieces never lose. A blade dense with nie, kinsuji and sunagashi that would read as a high Sōshū hand at first sight is returned to Ko-Uda by its darkened, standing jigane and its subdued temper, and the published sources are explicit that the resemblance stops at construction. Against the true Sōshū masters the contrast runs through his own grounded traits rather than theirs: the Yamato hataraki he never sheds, the hakikake and kuichigai-ba and uchinoke, and the blackish steel that no Norishige or Gō blade shows. His sons Kunifusa and Kunimune carried the school forward into the Nanbokuchō period, Kunifusa drawing the Sōshū tradition into the Uda manner, and the Kunimitsu name itself was taken up by several later smiths, the published record placing one signed blade with the second generation and another with the Ōei-era Kunimitsu of the early fifteenth century.
The whole of his recorded work sits in the Juyo tier, where ten blades are held, a mix of ō-suriage mumei katana attributed to the founder as Ko-Nyūdō Kunimitsu and signed Uda Kunimitsu tachi and tantō of the later generations. He has no National Treasures and no Important Cultural Properties, and the published record preserves no daimyō provenance or museum holding for his blades, so the honest account is of a school name carried by Juyo-ranked work rather than of a roll-call of famous swords. The NBTHK singles out the best of these for the soundness of both ji and ha, calling one darkened katana a piece of restrained, austere quality (渋味のある優品), and naming the nie along its habuchi as the Uda tell (刃縁の沸のつき方に宇多の特色がみられる). A Kunimitsu blade is not beyond reach in the way a National Treasure is, since the body that survives is Juyo and from time to time one of the signed later-generation pieces or an attributed mumei katana changes hands, but the founder's own securely first-generation work is among the rarer things a collector of the northern schools could hope to encounter, and most of what exists is held rather than traded. For a student of how the Yamato and Sōshū currents met in the northern provinces, his blades are the place where that meeting can actually be seen.
Tomonori (友則) — Mainline · 1390-1394. Jūyō. Four signed blades carry the name Tomonori (友則) into the present, each cut with a thick two-character mei toward the mune of an ubu or modestly shortened tang, and on the earliest the published sources remark that a signed, ubu-nakago tachi of this kind is a rare survival for the school. Tomonori is a smith of the Etchu Uda school, working from the late Nanbokucho into the early Muromachi. His line began when the monk-smith Ko-Nyudo Kunimitsu came north from Uda District in Yamato Province and settled in Etchu in the late Kamakura, carrying a Yamato-derived manner into the northern provinces; through the Nanbokucho the school sent out smiths such as Kunifusa, Kunimune and Kunitsugu, who re-used its names down the generations, and it flourished into the late Muromachi. The term Ko-Uda is reserved, within that descent, for the work of the late Kamakura through the Nanbokucho, and it is among the Ko-Uda smiths that the published record places these tachi. The reference works list five Uda smiths who used the name Tomonori, the oldest active around Meitoku and the line continuing to the Eisho, and the surviving signed blades are appraised as the earliest, the Tomonori of around Meitoku.
The published record reads his hand two ways, and the two manners are the heart of recognizing him. One is quiet. Over a tight itame that flows a little and stands with a whitish cast he tempers a narrow or medium suguha, mixing in ko-gunome and kuichigai-ba, ashi and yo entering and the nioiguchi drawn tight and bright, nioi predominating and the habuchi frayed into hotsure formed in fine nie. The disorder is kept small, the boshi runs straight and rounds into ko-maru with a slight turn-back, and on the late-Nanbokucho tachi the published sources judge that this register 'displays one characteristic style of this smith, is of good workmanship, and both ji and ha are sound.' The other manner is loud. The same itame, mixed now with mokume, stands more openly and takes a darkish tone, ji-nie adhering well and fine chikei entering, with yubashiri and tobiyaki breaking into the ji; over it a wider suguha or a shallow notare breaks into gunome and togariba, the tempered width widening in the upper half, coarse nie spilling into the ji and uneven nie in patches, until abundant tobiyaki and muneyaki rise to a hitatsura and the boshi is tempered deep into a flame.
The jigane is the constant beneath both hands. It is itame throughout, on the quieter tachi tight and flowing with a slight admixture of mokume and a whitish surface, on the nie-laden blades more open and standing, mixed with mokume, set with ji-nie and threaded with fine chikei, and darkish in tone. That dark steel is the feature the published sources lean on to fix his province, the kodachi read as associated with the smiths of the northern provinces by its dark color. The activity in the hamon tells the older half of the same story. The plentiful nie, the sunagashi running through the temper, the kinsuji and the brushed hakikake at the tip are read as a Yamato character carried down from Kunimitsu's migration: 'in both ji and ha the nie is plentiful, and from the frequent sunagashi and the abundant hakikake a Yamato disposition is evident,' the published sources say of the kodachi, before turning to the dark steel that ties the same blade to the north. The two readings, Yamato in the activity and Etchu in the color, sit together in a single piece and are the kantei the institution draws.
His four blades fall cleanly into those two registers, and the split runs partly with form and date. The quiet suguha hand carries the two tachi the records read as the earlier work, one a slender blade with deep koshizori and a small kissaki in the old fashion, the other appraised as the Meitoku-era smith, both tight in the ji and restrained in the ha. The nie-laden hand carries the kodachi and the latest, widest tachi, where the temper departs the quiet base for gunome, togariba and a hitatsura; on that broadest tachi the mihaba is wide with a pronounced taper, the kasane thick and the curvature high, and the published sources find in the deep flame boshi taken with the dark standing ji and the all-over temper that 'the characteristics of northern-province work are markedly manifest.' The dating is argued against the old directories rather than assumed: an entry grouping Tomonori with the Etchu Norishige line around the Kenmu era is held not to accord with the earliest tachi, and another placing him in a Kaga-resident second-generation Uda line is judged too late, so that each blade is fixed instead by its own ji and ha to the Nanbokucho and early Muromachi.
Within the school he is a known quantity rather than a founder or a head, and the published record is careful about how much can be built on him. His own traits lead the appraisal: the standing dark itame, the coarse nie spilling into the ji, the tobiyaki and muneyaki rising to a hitatsura and the flame boshi mark his nie-laden work, while the tight whitish suguha with ko-gunome and a bright nioiguchi marks the quiet half, and it is the presence or absence of the streaming nie that sorts one of his blades into one register or the other. No successor line is drawn through him; with only four signed blades the corpus is too thin to extend the school forward in his name. What the sources do say is that other works of his have likewise reached Important Sword rank, and that among the Uda group, whose extant works are not numerous, 'he was a smith of high technical ability,' a judgment placing him above the run of the school without making him its head.
His whole designated record is four Juyo tachi and kodachi, with no National Treasure or Important Cultural Property among them and no piece carrying a recorded daimyo provenance, so the connoisseurship rests on the blades themselves rather than on a roll of famous holders. That four signed pieces survive at all is the point the school's students return to, signed Uda work being uncommon, and the latest tachi is valued expressly as documentary material, the published sources calling it 'a fine resource for the study of this smith' and noting that it appears in the Kozan oshigata before a fourth mekugi-ana was bored, with the tang annotated 'Etchu work' (越中物). For a collector this is a name met through the Juyo tier, not held in a museum: the blades are kept, not traded, and one reaches the market only from time to time and with patience, but a signed Tomonori (友則) when it appears carries the rarer of the two things the school offers, a name surviving in the smith's own hand and a workmanship the institution ranks among the most able in the Uda line.

Phase 2 · Uda (宇多) · 1390 – 1596
Where Ko-Uda closes with the Nanbokuchō generations, the chapter that follows opens in early Muromachi and runs to the end of the period. The setsumei draw the boundary plainly: works that descend no later than Nanbokuchō are called Ko-Uda, while everything thereafter is referred to simply as Uda. This later phase is the long Muromachi continuation in Etchū, where the Kuni-named line that began with Ko-Nyūdō Kunimitsu of Uda District in Yamato extends across successive generations sharing single names. Kunihisa, read by the *meikan* as son of Kunifusa and active from the Ōei era, runs through several generations down to the close of Muromachi; Kunimune carries from Nanbokuchō into Muromachi with dated pieces around Bunmei; and the later registers add Kuninaga, Kuniyoshi, Hirakuni, Sanekuni, Kunikiyo, Tomohisa, and Kunitsugu, names the sources place from Eikyō through Tenshō. Because individuals individuate little, a signed blade of this phase is appraised as the manner of its dated moment rather than the hand of one smith.
The steel of the later phase keeps the school's northern foundation while standardizing its expression. The setsumei describe *itame* mixed with *mokume*, the grain overall standing (*hada-dachi*) and tending to flow (*nagare*), with *ji-nie* adhering and *chikei* entering; the *jigane* leans blackish, and a *shirake-utsuri* stands distinctly in the *ji*, sometimes with *ji-madara* mottling. Over this the temper most often opens as a *suguha*-based or *chū-suguha* line into which *ko-gunome* runs continuously from base to point, *ashi* and *yō* entering, *ko-nie* adhering along a bright *nioiguchi*, with *sunagashi* and occasional *kinsuji*. A second, more agitated face mixes *gunome*, *ko-notare* and pointed *togariba* with thick *nie*, *yubashiri* and *tobiyaki* that on a Kuninaga *wakizashi* tend toward *hitatsura*. Against the earlier Ko-Uda this reads more regularized: where the early generations stayed close to their Yamato and Sōshū models with archaic *ji-ha*, the later hands settle into the elongated Ōei *tantō* form (broad for its width, with *uchizori*) and, in the *katana*, the wide *sun-nobi* sugata of advancing Muromachi. The Kunitsugu *katana* shows this drift toward coarseness directly, its *itame* standing and rough, the *nie* uneven and the temper darkening at the edge.
To separate later Uda from Ko-Uda is to read the steel before the temper. The whitish, standing *jigane* with its blackish cast and *shirake-utsuri* returns a blade to this phase even when a *nie*-laden *midare* recalls Sōshū at first glance, and a tightly forged *ko-itame* may, as with the better Kunihisa pieces, approach Rai Kunimitsu or Rai Kunitsugu before the dark northern grain brings it home. Distinctive markers recur across the named smiths: the *bōshi* that becomes pointed and is tempered down with a long *kaeri*, the flaring (*susodoshii*) *nakago-jiri*, somewhat coarse rounded *nie* mixed within the *ha*, and the particular shaping of the character *kuni* in the signature. Dated and signed pieces anchor the chronology, from a Kunihisa *tantō* of Ōei 7 to a Kunimune *wakizashi* placed around Bunmei and Hirakuni and Sanekuni works set near Tenbun. Provenance for the phase tends toward settled holding, with examples resting in the Imperial Collection rather than circulating.
Kunimune (國宗) — Mainline · 1429-1479. Jūyō. One signed Uda Kunimune katana carries a Bunmei 11 date of 1479 cut on the reverse of an essentially ubu tang, and that single dated blade fixes the smith his name records best: a maker of the Etchū Uda school working in the middle of the Muromachi period. The published sources hold the first-generation Kunimune to be a son of Ko-Nyūdō Kunimitsu, the founder who carried the line north from Uda District in Yamato to Etchū around the Bunpō era at the close of the Kamakura period, and the younger brother of Kunifusa. The name then continued through several generations from the Nanbokuchō period down through the late Muromachi and on into the shintō era, so that a signed Uda Kunimune is read less as one hand than as the school manner of a period. Because the school's smiths individuate little, the published record appraises the surviving signed work by shape and the character of ji and ha rather than by an individual signature, placing the dated and dateable pieces around the Bunmei era when the Uda school flourished.
His work is read in two faces over one jigane. The quieter is the Yamato root the school never lost, seen most plainly on a signed ubu tantō in hira-zukuri with customary uchizori and a gomabashi carving. There the kitae is a ko-itame with masame-hada mixing in toward the edge, ji-nie adhering and chikei entering, and over it the temper is a chū-suguha with the nioiguchi somewhat tight, ko-nie adhering, the boundary near the hamachi tending toward yakikomi, the bōshi running straight into a ko-maru. The published sources read this register as a clear statement of origin, observing that the forging in which flowing masame mingles with the grain vividly expresses the Yamato tradition (流れ柾が交じる鍛えに大和伝をよく表わしており) and that the blade as a whole displays the distinctive character of Uda work (総体に宇多物の特色をよく示している).
The more active face is the school's Muromachi midare, the manner the published sources date to around the Bunmei era from the shape and the character of ji and ha. Over an itame mixed at times with mokume, flowing and standing rather than lying flat, the temper is a gunome broken by ko-notare, ko-gunome, chōji-like elements and a pointed tendency, with ashi and yō entering well, ko-nie adhering and sunagashi running frequently. Here and there slight yubashiri and nijūba appear, and on the widest blade the yakihaba broadens until from the middle upward it reaches the shinogi and around the monouchi shows an overall hitatsura-like temper, the bōshi a midare-komi vigorous in nie and carrying tobiyaki, tempered down long into the tang. On the calmer pieces that turnback becomes ko-maru-like and shows hakikake. The published sources call one such wakizashi a fine example in which the nioiguchi is bright and ko-nie adheres well, demonstrating not only the maker's style but the distinctive character of the whole Uda school (匂口が明るく小沸がよくついた作柄を見せており、同工のみならず同派の特色をよく示した佳品).
Under both faces lies the one jigane the appraisal turns on. His is an itame that flows and tends to stand, masame mixing in toward the edge, ji-nie adhering and chikei intermingling, and it is this northern, Yamato-derived steel that returns an Uda blade to its school when the temper alone might recall a Yamashiro or Sōshū hand. The carving on his blades extends the same Yamato temperament: the dated wakizashi bears long bonji set one above another with a suken below on the omote, and three bonji with a koshihi in kaki-nagashi on the ura, work the published sources judge splendid. The signatures are a four-character mei cut with a fine or somewhat thick chisel below the mekugi-ana, and the tangs are ubu or only very slightly machi-okuri, the feature that makes these blades documents as much as swords.
What sets his work apart is read through his own grounded traits rather than through any borrowed comparison. The flowing, standing itame with its mixed masame, the frequent sunagashi, and the gunome carrying pointed elements and ko-notare are the marks the published record names as the Uda character, against which his single suguha tantō stands as the quiet Yamato counterpart. The published sources are explicit that this is a school appraisal: they record the founder's migration from Yamato to Etchū, the descent of Kunimune from Kunimitsu and his place beside Kunifusa, and the continuation of the name through several generations, and they assign the dated and dateable signed pieces to the Bunmei era on the evidence of shape and workmanship. Across the corpus the resemblance to the Sōshū-leaning Uda manner of the Nanbokuchō generations is present in the nie activity, while the brightness of the nioiguchi and the standing northern jigane keep the verdict with the Uda school.
The whole of Kunimune's official record is held in the Juyo tier, where four signed blades survive across tachi, katana, wakizashi and tantō, with Fujishiro rating him Jō-saku and the Tōkō Taikan placing him at 300. He has no National Treasures and no Important Cultural Properties, so the honest account is of a school name carried by Juyo-ranked work and by its value as research material rather than of a roll-call of famous swords. The published sources single out the dated tachi for exactly this, noting that ubu signed tachi of this period are few and that the blade is therefore valuable source material (この時代の生ぶ茎、有銘の太刀は少く、好資料でもある), and they read the dated katana as an important document for research into the smith and the school, sound in both ji and ha. Two of his blades are recorded in the Imperial Collection, the most distinguished provenance his work carries. For a private collector the signed Uda Kunimune pieces in the Juyo tier come to market only from time to time and with patience, a maker whose blades reward the student of how the Yamato tradition was carried into the northern provinces more than the chaser of a celebrated name.
Moriyoshi (守吉) — Mainline · 1394-1428. Jūbun. Smith of the Etchū Uda School.
Kunihisa (國久) — Mainline · 1394-1428. Jūyō. Uda Kunihisa is the Ōei-era hand of the Etchū Uda school, the line the reference registers carry from Ko-Nyūdō Kunimitsu, the monk-smith who migrated from Uda District in Yamato to Etchū at the close of the Kamakura period and whose name flourished into the late Muromachi. The *Meikan* records Kunihisa as the son of Kunifusa, in another reading the son of Kunimune, gives him the studio name Uemon Saburō, and dates the first generation to Ōei, the same name then continuing for several generations through the Hōtoku and Bunmei eras toward the end of Muromachi. Of that long line he is the one hand the published sources treat as typical of the school and read against its founder. His work survives signed, a thing rare among Uda smiths, and the body of it is the long early-Muromachi *tantō*, broad for its length and with little or no curvature, that the school favored over the *tachi* and *uchigatana* it seldom made, joined by a few *wakizashi*, a *tachi*, and even a great spear. One of his blades carries a date of Ōei 7, which the judges hold to predate even the recorded examples of the line, calling it the earliest of all and "a valuable document, and besides of fine make" (資料的にも貴重であり、かつ出来が優れている).
Kunihisa is read first off the steel, for his temper is the school idiom and it is the *jigane* that carries him. On the calmer blades he forges an *itame* that runs and stands, flowing slightly toward *masame*, the steel turning whitish so that a *shirake-utsuri* or a faint *bō-utsuri* stands in the *ji*, with *ji-nie* throughout. Over it he tempers a *chū-suguha* or a *suguha*-toned line, opening shallowly into *notare* with pointed *gunome* and *ko-gunome* mixed in, *ashi* entering, the *nioiguchi* drawn tight, *ko-nie* well adhered, and along the *habuchi* the Yamato activity of *kuichigai-ba* and *hotsure* that names the school's old province. The published sources call exactly this combination, a whitish standing *itame* under a tight *chū-suguha*, the very type of the Uda hand, and on one signed *tantō* of just this make they write that "this is precisely that type, and the make is good" (まさにその典型であり、出来がよい). Through the *ha* run *sunagashi*, which lie on nearly every surviving blade, and *kinsuji* through most, the *nie-deki* activity that holds steady whether the temper is calm or roused.
The second manner the sources draw from him is the Sōshū-leaning one, which they trace to Kunifusa's study under Etchū Norishige, granting that much Uda work of this period calls the Sōshū tradition to mind while holding that none is of pure Sōshū construction. On the dated Ōei 7 *tantō* the *jigane* is an *itame* with *moku* and *chikei* entering, the temper a shallow *notare* mixed with *gunome*, *ko-nie* applied and *kinsuji* running, and the judges read it plainly as Sōshū-leaning. In this register the body broadens, the *nie* thickens and grows at times coarse, *yubashiri*, *kinsuji* and *sunagashi* run more freely, and on the finest blades a round, luminous *nie* scatters through the *yakiba*. The *bōshi* turns *midare-komi*, the tip pointed or pushed up, the turnback long and at times deep. A nie-laden Kunihisa blade reads as Sōshū at first glance, and the published sources return it to Uda by the steel, the dark, whitish *jigane* and the *nioiguchi* that holds rather than glows.
Beyond the school formulas the sources name what is Kunihisa's own, and it is a quality of *jigane* rather than a new shape. His finest *tantō* and *wakizashi* are a *ko-itame* so well forged and compacted that the steel turns refined and bright, *ji-nie* laid on densely and at times dust-fine as *ji-nie mijin*, a *jigane* darkish and whitish with a faint *utsuri*. Through the *yakiba* runs the round, luminous *nie* the school calls its own, the *ha* and *ji* alike clear, and on one such blade the judges find "in the well-forged, refined surface, Kunihisa's individuality can be seen" (国久の個性が着て取れる), naming the same piece "an outstanding work among the finest" (屈指の優品である). The Uda *jigane*, they note in passing, runs to two kinds, one that stands and one that compacts and gathers abundant *ji-nie*; Kunihisa is read on the side that gathers and refines. His blades are otherwise plain in their fittings, a *bō-hi* or *koshi-hi* run out on the spear and the *tantō*, *gomabashi* and a *suken* carved on others, the carving kept simple beneath the working of the steel.
What distinguishes Kunihisa within the late Uda line is the brightness of that refined steel, which the sources read toward Yamashiro rather than toward his own school's duller hands. On a *tachi* whose construction stands high in the *shinogi* and runs to a *ko-gunome midare* with *hotsure* and *sunagashi* and a *yakizume bōshi*, they call the manner Yamato in temperament and "a work showing the characteristics of Uda" (宇多物の特色を示した一口である). On his best *wakizashi* and *tantō*, where the *ko-itame* tightens and the bright round *nie* gathers, they go further, writing that the blade "calls Rai Kunimitsu and Kunitsugu to mind at a glance, a fine work of Kunihisa" (一見来国光・国次らを髣髴とさせる、国久の秀作である), and of another that it is "of a make all but mistakable for Rai Kunimitsu or Kunitsugu" (来国光や国次に紛れんばかりの出来映え). His own *shirake-utsuri* and standing *itame* set him apart from the Yamashiro hands he approaches, and his refinement sets him apart from the plainer Uda smiths around him; the verdict in every case rests on the steel, not on the temper.
For the collector Kunihisa is a soundly recorded provincial name rather than a famous one. He has no National Treasures and no Important Cultural Properties; his record runs entirely through the Juyo rank, where ten of his blades are held, the *Tōkō Taikan* rating him at four hundred and the *Fujishiro* registers placing him at *chū-jō saku*, a competent middle-upper hand. Of his blades whose present whereabouts are recorded, several rest with shrines and a museum, among them Yasukuni Jinja, the Kunōzan Tōshōgū and the Suiboku Museum, the kind of long, settled holding that keeps most designated work off the market. With ten Juyo blades on record and most of them held rather than traded, a signed Uda Kunihisa comes to a private collector only from time to time, and with patience; when one does, it is a clear window onto how the northern Uda forged at its Ōei height, the moment the school's steel ran bright enough to be taken, for an instant, for Rai.

Kunimune (國宗) — Mainline · 1394-1428. Jūyō. Smith of the Etchū Uda School.
Kunitsugu (國次) — Mainline · 1469-1487. Jūyō. The Uda school traces its origin to the late Kamakura period, when the monk Kunimitsu migrated from Uda District in Yamato Province to Etchu Province. Kunitsugu is a name borne by several generations within this lineage; reference works record the first as a brother of Kunifusa, active around the Enbun era (1356-1361), and the line continued through at least the Tenbun era (1532-1555). The school flourished particularly during the Muromachi period, producing a substantial body of work across long swords, tanto, and yari.
The Kunitsugu setsumei reveal a consistent Uda character: an *itame-hada* that tends toward standing grain (*hada-dachi*), sometimes mixed with *masame* or *mokume*, often with a slightly blackish tone to the *ji*. The tempering favors *ko-notare* mixed with *gunome* and *ko-gunome*, laden with clustered *nie*, frequent *sunagashi*, and intermingled *kinsuji*. A Nanbokucho-period tachi (Juyo, 23rd Session) displays "an *itame* forging with a tendency toward *masame*" and "a whitish *utsuri*," with *ko-gunome* mixed with *ko-midare* showing "abundant activities -- *ashi* and *yo*, well-formed *nie*, and *sunagashi*." A tanto of the Oei to Shocho era (Juyo, 15th Session) presents "the typical manner of Uda work from that time," with deep *nioiguchi* and thick *nie*.
The school's designated corpus includes a yari dated Bunmei 17 (1485) -- a rare signed spear predating the common Muromachi-period proliferation of such weapons -- which the NBTHK deems "valuable as important material for research into the Uda school." Across blade forms and periods, the Uda Kunitsugu works maintain a robust, *nie*-laden aesthetic tempered by the provincial vigor of their Etchu origin.
