Phase 1 · The Bitchū Senoo School (瀬尾) · 1180 – 1350
Yukizane (行眞) — Mainline · 1260-1261. Jūbun, Jūbi, Tokujū, Jūyō. Yukizane (行真) was a swordsmith of the Seno group in Bitchu Province, active during the Kamakura period. The Bitchu smiths are broadly divided into two lineages: the Aoe smiths — Moritsugu, Tametsugu, Sadatsugu, and others — who commonly employ the character "tsugu"[[c:1]] in their names and forged along the basin of the Takahashi River, and the Seno smiths, situated to the east toward Bizen, who rarely incorporate that character. Seno is known as a place developed by Seno Taro Kaneyasu, a retainer of the Taira. The *Kokon Meizukushi* records Yukizane as a son of Suemasa within the Seno lineage, and sword-mei manuals list several smiths of this name from the Kamakura period through around the Oei era. Extant works by Yukizane are few, making each surviving example of considerable documentary importance.
Yukizane's tachi present an old-fashioned, imposing form with wide *motohaba*, a pronounced taper to the tip, lofty *koshizori*, and a *ko-kissaki*. The forging shows *itame-hada* mixed with *mokume*, with a slightly standing grain and areas of *chirimen*-like texture toward the edge — a recognized hallmark of Seno workmanship. Fine *ji-nie* forms densely, *utsuri* appears, and *jifu*-like mottling gives the ground a distinctive *jiban*-toned character. The *hamon* is based on *suguha*, mixed with *gunome*, *ko-midare*, and a *ko-gunome*-like feeling; *ashi* and *yo* enter well, *nie* forms throughout the temper, and fine *sunagashi* and slight *kinsuji* appear. The *boshi* is vigorously *hakikake*, becoming a flame-like *kaen*-style appearance — a particularly striking feature. The *nakago* typically displays *sujikai* or *o-sujikai* file marks with a finely chiseled two-character signature on the *omote*, clearly expressing distinctive features of Seno workmanship.
The NBTHK has described Yukizane's best works as possessing a dignified, imposing presence and a subdued, deeply flavorful character, with both *ji* and *ha* in *kenzen* — sound and well-preserved — condition. As the *Genki Mekikisho* observes, Seno blades convey a temperament "resembling Bizen work," and Yukizane's hamon indeed carries something of a Ko-Bizen flavor even as the *jigane* and file-mark conventions identify the hand unmistakably as Bitchu Seno. It is especially desirable that his surviving tachi retain *ubu* nakago with original signatures, providing irreplaceable source material for the study of this maker.
Saneyuki (眞行) — Mainline · 1293-1299. Jūbun, Jūyō. Smith of the Bitchū Senoo School.
Sukezane (助眞) — Mainline · 1232-1249. Tokujū, Jūyō. Sukezane was a swordsmith of the Senoo school of Bitchū Province during the Kamakura period. The Senoo district, opened by Senoo Tarō Kaneyasu, a retainer of the Taira clan, lay along the lower reaches of the Takahashi River to the east of Aoe, closer to Bizen, and the old appraisal texts *Genki Mekiki-sho* and *Kokon Mei-zukushi* divide the smiths of Bitchū into the Aoe and Senoo forges. The meikan genealogies list two smiths of this name: one a pupil of Noritaka working around the Jōei era (1232–1233), the other a pupil of Tsunetō placed around Bun'ei (1264–1275). Surviving examples are very few, and blades bearing his signature are accordingly treasured.
The Senoo smiths — Noritaka, Masatsune, Tsunetō, Koreshige, Yasuie, Hirotsune, Tsunezane, Moritsune, Sukezane, Tokizane, and Yukizane among them — seldom used the character *tsugi* (次) that was customary in Aoe signatures, and unlike the Aoe smiths of the same era they generally signed in tachi-mei. Sukezane's extant tachi preserve ubu, deeply koshi-zori shapes of dignified form. The *kitae* is itame or ko-itame mixed with mokume, tending toward a crêpe-like *chirimen-hada* with thick *ji-nie*, fine *chikei*, and *jifu-utsuri* standing out — the hallmarks of the Bitchū smiths. The *hamon* is a wide *suguha* base mixed with ko-gunome, kaku-gunome, or chōji, with abundant *ko-ashi* and *yō*, *nioi-gachi* with *ko-nie*, at times slanting (*saka-gakari*) in the lower half, and accompanied by *hotsure*, *kinsuji*, and *sunagashi*. As the old texts note, the workmanship "resembles Bizen work," carrying a Ko-Bizen flavor while at first glance approaching Aoe; the *yasurime* in ō-sujikai is a further mark of the province.
Sukezane's importance rests on the rarity of signed Senoo work surviving today. A signed tachi of 76.3 cm passed Jūyō at the 64th session and rose to Tokubetsu Jūyō at the 26th session; another, descended in the Bizen Ikeda family and accompanied by a Momoyama-period itomaki-no-tachi koshirae with bear-fur scabbard cover, holds Tokubetsu Jūyō rank from the 16th session; a third, an ubu tachi from the Kishū family collection, is Jūyō. The NBTHK descriptions repeatedly note that the Senoo forge still awaits fuller study, making each of these signed blades primary research material for the school.
