This blade is attributed to Mino Senjuin (美濃千手院), which is one of the most famous schools during the late Nanbokucho-late Muromachi period (Mid 14th-Early 16th century) in Mino province (today’s Gifu prefecture). According to NBTHK that appraised this blade, it was approximately made during the mid-late Muromachi period (Late 15th-Early 16th century). The school was located in Akasaka village near Sekigahara, an essential hub for transportation and military bases from ancient times. It is said that the Mino Senjuin school was founded by Sensui (泉水), the son of Yamato Koku Senjuin Shigehiro. Yamato region was one of the most famous sites for sword-forging during the late Heian-Kamakura period. Sensui moved from Yamato (today’s Nara prefecture) to Akasaka village in Mino province during the Nanbokucho period. Senjuin School in Yamato region There was a temple called Senjudo in Nara prefecture where Senju Kannon (Thousand arms) Budha statue was worshiped. And a group of swordsmiths who lived there was known as Senjuin (千手院). They belonged to Todaji temple. Senjuin School was founded by Yukinobu, who was the son of Yoshiyuki. Yukinonobu was originally a servant for Senjuin temple, a branch of Todaiji temple during the late Heian period (1086-1107), and eventually became an Okakae Kaji for the temple. This blade is appraised as a Hozon Token (保存刀剣) issued by NBTHK (Nihon Bijutsu Touken Hozon Kyokai:日本美術刀剣保存協会). *Please keep in mind that there are a couple of Kitae Kizu and black rust on the blade. Fuchi-Kashira The Fuchi-Kashira is decorated with butterflies rendered in gold over the black lacquer surface. The butterfly (chō, 蝶) is a symbolic motif in Japanese culture, representing transformation and rebirth, as it undergoes a remarkable metamorphosis from larva to chrysalis to adult form. For this reason, butterfly designs were favored by samurai. Furthermore, as butterflies are often seen in pairs, they are also associated with harmonious relationships and happy marriage. Tsuka and Menuki The theme of this Menuki is likely Fenghuang (鳳凰, also known as Houou in Japanese), one of the four mythical creatures collectively known as the “Shirei” (四霊), along with the Kirin (麒麟, Qilin), Kame (亀, Turtle), and Ryū (龍, Dragon). The Houou is a divine beast that resembles a blend between a chicken and a peacock. In ancient China, it was regarded as an auspicious omen, believed to appear only during the reign of a virtuous and wise emperor. In Japan as well, the Houou is admired for its elegant form and is often used in traditional art and decoration. Tsuba and Habaki This tsuba features a design based on the paulownia and arabesque vine motif (桐唐草, kiri-karakusa). This traditional pattern combines the kiri (paulownia tree)—a well-known symbol of good fortune in Japan—with karakusa (arabesque vines), which represent vitality and longevity. The karakusa design is inspired by the vigorous growth of creeping vines, whose endlessly extending tendrils have long symbolized eternal life, prosperity, and the continuation of family lines. In Chinese tradition, the vine’s trailing stems (man-dai, 蔓帯) are phonetically associated with the idea of “ten thousand generations,” further reinforcing its auspicious meaning. As a result, this motif has traditionally been favored in celebratory occasions such as wedding ceremonies and gift exchanges, symbolizing blessings for longevity and familial prosperity. Saya This scabbard is finished in red lacquer. Owing to its excellent waterproof properties, lacquer has been widely used throughout Asia since ancient times. As the blade of a Japanese sword is made of iron, it is highly susceptible to moisture, which is its greatest enemy. To protect the blade from deterioration, craftsmen developed the technique of coating the scabbard with multiple layers of lacquer. This process not only prevents moisture but also protects against rain and snow from penetrating the interior. The nushi (塗師, lacquer artisans) emerged as specialists due to the advanced skills required to carry out these intricate techniques. Authentication Paper They authenticated the blade on August 22nd in the 20th year of Heisei (2008). They appraised it as Hozon Touken, the blade worth preserving for Japanese society.

Akasaka in Mino Province was the seat of a group the NBTHK setsumei records under two names, Mino Senjuin and Akasaka Senjuin, and the documents are consistent on its descent: the line traces to the Yamato Senjuin tradition, whose craftsmen relocated north into Mino. The setsumei place that migration around the end of the Nanbokuchō period, with the group then flourishing into the Muromachi. According to the Kōsei Kotō Meikan as cited, the founder was Kuninaga, set around the Jōji years, with the line carrying the Kuninaga name onward to the Meiō era; Kunishige is placed near Kenmu and is represented by surviving work. The smiths the setsumei name span this arc: Kuninaga, Kunishige, and Kuniyuki of the Nanbokuchō; the joint spear-makers Hironaga and Hiroshige and the ancient smith Tōga of the Muromachi; and later hands signing Dōei, Dōin, Yasumichi, or simply Senjuin. The documents also chart a parallel current, the Echizen smith Kuniyuki of Tsuruga (signing Esshū or Etsushū) who entered Mino between Ōan 6 and 7, alongside Kaneshige and Tametsugu who likewise moved from Echizen. The shared vocabulary of these blades begins in the forging: itame mixed with mokume that flows toward masame, with grain that stands out (hada-dachi), ji-nie, chikei, and a whitish cast (shirake-gokoro) the setsumei return to repeatedly. The temper divides along two lines the documents describe as habitual. " The other runs hotter: notare mixed with gunome, abundant nie, yubashiri, tobiyaki, and muneyaki building toward hitatsura, the manner that marks the Echizen Kuniyuki current.
The bōshi tends to midare-komi with hakikake and a pointed return. To recognize the hand, the setsumei direct attention to the masame-bearing, whitish ji carrying Yamato traits of hotsure and kuichigai-ba, set against a gunome base that leans toward emerging Mino-den character. For kantei the documents are explicit that this line "consistently displays a stronger Yamato character" than the Seki-mono otherwise encountered, and that its hamon "stands at a considerable remove from typical Mino workmanship," though the jigane keeps it within that milieu. Signed pieces carrying an individual maker's name are noted as scarce, which raises the documentary weight of the dated and signed examples the setsumei single out: the Kuninaga tantō dated Ōan gannen, the signed Kunishige and Kuniyuki tachi, and the Esshū Kuniyuki wakizashi dated Sadaji and Ōan whose signatures incorporate Fujiwara. Among named works the setsumei cite the ōmi-yari signed Senjuin with its vermilion-lacquered long-shaft mounting, the joint spear of Hironaga and Hiroshige, and the wakizashi by Tōga held to copy the Genji treasure Higekiri. Provenance is recorded for the Tōga piece, formerly of Tanzan Shrine in Yamato, donated to the Imperial Household and recorded in Honma's inventory of the Imperial collection, with two further Tanzan blades assigned to the Nanbokuchō. The documents place these works across the Tokubetsu-Jūyō and Jūyō registers and Honma's inventory of the Imperial collection, reading the group as a Yamato offshoot that carried its masame-grounded manner into Mino while the gunome base turned toward Mino-den.
