Sengoku Seki was an industry: smiths organized under their tutelary Kasuga shrine, arming the war bands of central Japan. Magoroku Kanemoto’s sanbonsugi and the finest Kanesada work prove quality survived inside mass production.
This blade was signed by Noshu Seki Kanefusa (濃州関兼房) during the late Muromachi period in the Eiroku Era (1558-1570) . Noshu is another name for Mino province (Today’s Gifu prefecture) and Seki is the city located in Mino Province, which was the most active center of sword production in the region. The maker’s name, Kanefusa, lasted a few generations during the Muromachi period. This blade was made by the late-gen Kanefusa in the late Muromachi period in the Eiroku Era (1558-1570) based on NTHK appraisal. The first-gen Kanefusa was active during the Eikyo era (1429-1441: mid-Muromachi period), and he was known as the son of Kaneshige, who belonged to Yoshisada school in Seki city. In Mino province, Seki City was the most active sword-forging site. And the first-gen Kanefusa was famous for inventing a particular Hamon (tempering line) called Kenbō Midare (兼房乱れ). The swordsmiths who resided in Mino province developed particular sword-forging tradition called MINO-DEN. Its characteristic is the TOGARI(Pointed shapes protruding from the Hamon ) in a classic straight line and random temper line with some white Utsuri. MINO-DEN had its origin from YAMATO-DEN in the late KAMAKURA period(1280-1330). It flourished in the MUROMACHI period(1333-1573) and continued until the EDO period(1603-1868). MINO-DEN especially prospered during Sengoku Jidai(Warring State period) due to the high demand for weapons. And the location of Mino province beat others. Akechi Mitsuhide controlled Mino province, and Nobunaga Oda ruled Owari province, and Tokugawa Ieyasu was the lord of Suruga (Neighboring areas). There was high demand from those powerful feudal lords and their retainers. Furthermore, so many wars occurred between the Kanto region and the Kyoto area. Mino was located in the middle, making feudal lords feel convenient to order swords from MINO-DEN. The blades forged in MINO provinces also had the reputation of its practical design and sharpness. Many feudal lords demanded swords forged in the Mino province. *Please keep in mind that there are a couple of Kizu on the blade. Fuchi-Kashira The theme of the Fuchi-Kashira is the dragon (龍, Ryu). Initially, the dragon is an imaginary creature found in ancient Chinese traditions or myths. Furthermore, it is regarded as a symbolic beast of auspicious signs. Its body is likened to nine animals: antlers are deer, the head is a camel, eyes are demons, the neck is a snake, belly is Mizuchi (蛟, mythical animal in Japan which looks like a snake and have a horn and four legs), scales are fish, claws are falcons, palms are tigers, and ears are cows. It was thought that the dragon would reign at the top of all animals because of its odd-looking appearance. Also, in Japan, there is a belief that worships dragon as a water god and is called Ryujin Shinkou (竜神信仰). Since rice cultivation flourished in this country, water is always an essential resource. Therefore, the dragon motif has been familiar to Japanese people since a long time ago. Tsuka and Menuki The theme of the Menuki is the Karajishi (唐獅子, Chinese lion) . The Shishi (獅子) means a lion in Japanese, and the Karajishi is a lion brought from the continent to Japan in the Toh period (唐, Tang dynasty, 618-907). The Karajishi typically has curly hair for its head, neck, body, and tail, as seen on this work. In Buddhism, the Karajishi is regarded as a symbol of wisdom, and Monju Bosatu (文殊菩薩, Manjushri Bodhisattva) rides lions. According to a theory, the Karajishi is the origin of Komainu (狛犬, stone guardian dogs that exorcize evil spirits). It shows this animal motif has been familiar to Japanese people since ancient times. There is a Houwa (法話, Buddhist monks tell the story of Buddhism in an easy-to-understand manner) that treats the Karajishi and this flower. The lion is called the king of the beasts. However, even this invincible animal has only one fear: a bug in the lion’s body. This pest grows in the lion’s hair and eventually breaks the skin and bites the flesh. Nevertheless, it dies if it is exposed to the night dew of a peony. Therefore, the lion rests under peony flowers at night, looking for a haven. The design of these sword mountings might have been quoted from this story. Peony represents happiness, wealth, nobleness, and gorgeousness. This flower pattern has been treated as a kind of good-omen motif; people regarded it as a rich harvest sign. Peony is called “Botan” in Japanese. When we write this flower’s name in Japanese, its second letter means mountain hermit medicine that would give us eternal youth. Based on the meaning of this letter, the peony pattern symbolizes eternal youth and longevity. Tsuba and Habaki This tsuba is decorated with a Gosan no Kiri (五三の桐) motif. It is crafted from iron and finished using the sukashi-bori (openwork carving) technique, in which portions of the metal are carefully cut away to create an elegant pierced design. The Gosan-no-Kiri design, depicting paulownia leaves and flowers, has long been a popular and auspicious pattern in Japan. Historically, it was used by the imperial family and high-ranking authorities. Today, its use is permitted more broadly and it is widely appreciated as a family crest. Saya This Saya is covered with black lacquer. Due to its high waterproof effect, lacquer has been used since ancient times in Asia. The blade of a Japanese sword is made of iron, and moisture is the greatest enemy of iron. For the purpose of carrying the blade without degrading it, people devised a method of coating the scabbard with lacquer. To prevent not only moisture but also rain and snow from penetrating the inside of the scabbard, it was necessary to apply multiple layers of lacquer. The Nushi (塗師, lacquerers) was born precisely because advanced techniques were required to handle the complicated processes. *Please note that the surface of this Saya has some minor damage. Authentication Paper NTHK, also known as NPO Nihon Touken Hozon Kai, is the oldest organization for sword authentication of Japanese swords in modern times. It was established in 1910 during the post-Samurai era. They authenticated the blade on February 15th in the 16th year of Heisei (2004). Registration Number It is called Jyu Hou Touken Rui Torokusho (銃砲刀剣類登録証).

Kanefusa is among the best-known smiths of the Mino tradition in the Muromachi period, working from the town of Seki in Noshu. According to sword-signature reference works, his origins lie with the Akasaka smiths, and the first generation is considered to have been Shigefusa, active around the Kakitsu era (1441-1444). The name continued under successive generations from the mid-Muromachi period into the shinto era. Among extant dated works, examples are recorded from the Bunmei, Tenbun, Eiroku, and Tensho eras, with the greatest number of surviving pieces — including those bearing two-character signatures — dating from approximately Eiroku through Tensho. Most long-signature examples are cut "Noshu Seki-ju," confirming that the smith resided in Seki.
Kanefusa is particularly famed for having devised the temper pattern known as "Kanefusa midare" (also termed Kenbo midare), an idiosyncratic gunome-choji whose heads are rounded and whose waists constrict. Beyond this signature style, works also appear in notare and in sanbonsugi-midare in the manner of Kanemoto, demonstrating a broad range of expression. The forging typically shows itame-hada with a tendency toward nagare, accompanied by ji-nie and an overall shirake-gokoro — a whitish cast characteristic of Mino workmanship. The nioiguchi tends toward tightness with ko-nie adhering, and finer examples display tobiyaki and muneyaki interspersed throughout, producing a varied and lively temper. The bold, vigorous style associated with later Mino workmanship is consistently evident.
Kanefusa's best works are praised by the NBTHK as notably vigorous and full of spirited force, with ample nikuoki and robust overall shape deemed particularly pleasing. Blades in sound condition are recognized as kenzen, with both ji and ha well executed. The flamboyant expression of the distinctive midare, combined with wide mihaba and o-kissaki, produces an imposing sugata of dignified presence. Several designated examples also bear gold-inlaid cutting-test inscriptions of considerable documentary value, attesting to the practical esteem in which these blades were held during the Edo period.

Seki (関), in Mino Province, grew from two roots set down in the Nanbokuchō period and rose to become the great center of mass sword production in the late medieval age. The published sources trace the wellspring of Mino swordmaking to Kinju (whose name the commentary also reads Kaneshige), counted since antiquity among the Masamune Jittetsu, the ten disciples of Sōshū Masamune, and to Kaneuji of the Shizu line; the Kokon Meizukushi records Kinju as a native of Tsuruga in Echizen who "crossed over to Seki and resided there," carrying the Sōshū-den manner east. Beneath that Sagami inheritance lay a Yamato foundation, legible in the Tegai descent of the Seki Zensada line through Kaneyoshi, so that the Mino-den the Seki workshops forged stands as a fusion of Yamato grain and Sōshū activity in nie. From this Nanbokuchō founding the name multiplied across the Muromachi period into Sue-Seki, the last and largest body of the tradition; its representative masters at the close of the old-sword age were Magoroku Kanemoto, famed for the sanbonsugi, and Izumi no Kami Kanesada, the smith called Nosada, while the Kanefusa, Ujifusa and Daidō hands worked beside them and the move of Wakasa no Kami Ujifusa to Kiyosu carried the Mino body to the threshold of Owari shintō. A common Mino vocabulary binds the Seki body, however widely its members range. The forging is an itame that stands and runs to masame, often mixed with mokume and nagare, over which rises the cool whitish shirake-utsuri of Mino steel rather than the bright midare-utsuri of Bizen; this pale, standing jigane is the constant tell the judges read first, present alike on Kinju's Nanbokuchō katana, Kaneyoshi's Ōei tachi and Nosada's late-Muromachi blades. Over it the smiths temper gunome into which the pointed togariba of Mino enters, with ko-nie clinging to a tight nioiguchi, ashi and yō, and sunagashi streaming through; the bōshi answers in midare-komi turning to a pointed or jizō-cast ko-maru swept with hakikake. From this shared grammar the individual hands diverge.
Kanemoto fixed the regular three-cedar sanbonsugi of pointed teeth; Kanefusa devised the rounded-head, constricted-waist "Kanefusa midare"; Kinju and the early founders held a calmer, rounder gunome away from the restless Shizu line, their work laid with thicker ji-nie and dry, standing grain. The late masters carried the manner to a higher finish: Nosada wove togariba among rounder forms for a broader temper than Kanemoto's one-sided file, and turned at times to a slender Rai-styled suguha with a hidden gunome; Kaneyoshi held instead to a cool ito-suguha, the disciplined Yamato face of late Seki, lightly broken with ko-gunome. A collector seeks Seki because it is the connoisseur's ground for reading Mino-den across a vast body of signed and attributed work. The kantei runs through the jigane first: the standing, masame-leaning itame and the whitish shirake separate a Seki blade from Bizen and Yamashiro, after which the pointed togariba, the dry nie, and the pointed or jizō bōshi confirm the province; the discriminations the judges draw, Kinju held apart from Shizu by his rounder gunome, Nosada parted from Kanemoto by his breadth, give the eye its anchors. Within the school the standing of the best members is settled: Magoroku Kanemoto for the sanbonsugi, Nosada whom the swordbooks call simply "an excellent master" and the most accomplished of the several Kanesada hands, and the early Kinju as a rare and precious founding name, his record running through the Jūyō tier with the signed pieces few and the long blades attributed den. Signature works carry real provenance: a Kinju tantō presented to the Tokugawa shogunal house in 1679, a Nosada katana borne by a chief retainer of the Kii Tokugawa and a tachi forged for the father of Takeda Shingen, a Kaneyoshi tachi transmitted in the Chikuzen Kuroda family. Beyond connoisseurship, Seki's blades earned a battlefield reputation for cutting; the full hiraniku and stout build of the Sue-Seki katana, made to sever, set the wazamono standing that made Mino the working sword of its age.

Mino in the Muromachi period
Sengoku Seki was an industry: smiths organized under their tutelary Kasuga shrine, arming the war bands of central Japan. Magoroku Kanemoto’s sanbonsugi and the finest Kanesada work prove quality survived inside mass production.
The NTHK’s principal certificate, issued for a blade of considerable quality. It confirms a genuine signature, or, for an unsigned (mumei) work, records the judges’ attribution to a smith or school. The paper carries a detailed worksheet with a numerical point score.
The NTHK (Nihon Tōken Hozon Kai, the Society for the Preservation of the Japanese Sword) is the oldest of Japan’s sword-appraisal bodies, founded in 1910, decades before the NBTHK. After the death of its long-serving head it divided into two successor societies, the NTHK and the NTHK-NPO, both of which continue to hold shinsa. NTHK blade certificates are known for a detailed worksheet that records a numerical point score alongside the judges’ written opinion (fitting papers carry the judges’ opinion without a point score), and the society is especially respected for its attribution of unsigned (mumei) work.
