Muromachi turned sword making into an industry: the uchigatana rose with massed infantry warfare, Osafune and Seki produced bundle swords beside custom orders, and the Ming trade carried Japanese blades abroad by the tens of thousands.
This is a signed katana by Kanabō Hayato no Jō Masazane, a leading smith of the Kanabō school from Nara. The blade measures 61.7 cm with 1.4 cm of curvature and comes with a complete, recently restored koshirae featuring a red-and-black textured lacquer saya and gold chrysanthemum menuki. It is accompanied by an NBTHK Hozon Token certificate and registered in Japan since 1951.

The Kanabō (金房) smiths worked in Nanto, the old name for Nara in Yamato province, from the end of the Muromachi period into the early Shintō era. Their relationship to any of the five established Yamato schools is not clearly fixed in the record, and the NBTHK setsumei treat the group as one that rose and flourished in Nara during the late Muromachi decades, with dated examples encountered from the Eishō era onward. The blades here name several hands. Masatsugu (政次), who signed as Kanabō Hyōe no Jō Masatsugu and as Kanefusa Hyōe no Jō Masatsugu, is described as the representative and best-known smith of the line. Masasada (政定), signing Kanefusa Saemon-no-jō Masasada, left an uchigatana dated Eiroku 2 (1559). " Rather than the classical Yamato-den manner of the earlier five schools, the Kanabō hand reads as a Muromachi uchigatana idiom that shares points with the Sue-Bizen and Sue-Seki spheres. The kitae is itame that flows into nagare and tends toward masame, with the grain often standing and growing large, and a whitish utsuri appearing in places. The hamon divides between two registers the setsumei repeatedly cite: a large gunome-based midare, the "hips" of the gunome opening out and mixed at times with togari-ba, chōji, or ko-notare; and a suguha carried on a tight nioiguchi.
Across both, ashi and yō enter well and stand out, ko-nie and ji-nie adhere, and sunagashi with kinsuji run through; the nioiguchi frequently takes a shizumi, subdued cast. The bōshi runs midare-komi, often with hakikake and a pointed or ko-maru return. The build tends to broad mihaba with sakizori on the swords, while naginata are conspicuously common, a production read as answering the demands of the warrior monks (sōhei) of Kōfukuji and the great Nanto temples. For kantei, the line is held by the flowing masame-tending itame, the broad gunome-midare with prominent ashi and yō over a tight or subdued nioiguchi, and the marked presence of naginata and long polearm blades among extant work. The setsumei single out Masatsugu's polearms as typical of his hand, several preserved with their vermilion-lacquer nagamaki mounts (shunuri nagamaki koshirae) and one black-lacquer naginata mounting, the fittings inferred to have been made together with the blade. The records grant that true masterworks within the group are rare, yet they describe individual blades by Masatsugu and Masasada with fine jigane, skillfully cut horimono, and workmanship judged excellent and dignified. Within the wider Yamato sphere the Kanabō stand as a late, utilitarian offshoot whose polearms and serviceable swords carry the group's name into the NBTHK register. Learn more →

The Muromachi period (1392 to 1573)
Muromachi turned sword making into an industry: the uchigatana rose with massed infantry warfare, Osafune and Seki produced bundle swords beside custom orders, and the Ming trade carried Japanese blades abroad by the tens of thousands.
Certifies a genuine blade worth preserving: a signature confirmed correct, or, if unsigned, an era, province, and school that the NBTHK can reliably identify.
The NBTHK (Nihon Bijutsu Tōken Hozon Kyōkai, the Society for the Preservation of Japanese Art Swords) is a public-interest incorporated foundation founded in 1948 and supervised by Japan’s Agency for Cultural Affairs (Bunkachō); it is based at the Japanese Sword Museum in Tokyo. Its expert panels physically examine each submitted work (shinsa) and issue a certificate (kanteishō) ranking it by artistic and historical merit. NBTHK papers are the most widely recognized standard of authentication for Japanese swords and fittings.
