Two courts, sixty years of war, and the most dramatic silhouettes in the sword’s history: broad blades, extended points, true ōdachi later cut down into the majestic katana collectors prize. The Sōshū manner was the style of the age.
NihontoWatchNihontoWatchThis work is a katana made between the Nanbokucho period and the early Muromachi period by Hoju, a descendant of the Mokusa smiths who developed the Japanese sword during the Heian period. The Taiheiki depicts the figures of samurai fighting the battles of the Nanbokucho period with swords such as this. The koshirae is a magnificent yet robust mounting featuring a Musashi tsuba, suggesting an excellent provenance. A custom-made metal fitting is attached to the koiguchi, and the combination of the grandiosity of the toshin and this bold koshirae makes it a sashiryo truly befitting a master swordsman like Musashi.

Among the swordsmiths said by old transmitted records to have worked in Ōshū (Mutsu and the wider northeast) from the Nara and Heian periods through the Kamakura age, the setsumei repeatedly observe that, of works actually surviving today, almost the only name that can be confirmed is Hōju (宝寿). The line is set within the Maikusa (Mokusa) sphere of Ōshū smiths, a group transmitted from the early Kamakura period onward; one tachi is described as a branch of the Maikusa smiths of Mutsu, and a Nanbokuchō entry pairs Hōju with Maikusa and, after Nanbokuchō, the Gassan group. The name itself was carried across a long span, from Kamakura through Nanbokuchō and into the Muromachi Ōei era, so that "Hōju" denotes a lineage rather than a single hand. A complicating thread runs through the corpus: one blade dated Enkyō 4 (1311) is signed Yamato-kuni-jū Tōmoto Hōju, raising the question of movement between Ōshū and Yamato, with the setsumei suggesting exchange of smiths through Shugendō mountain practice. Dated survivors anchor the chronology firmly, with inscriptions of Shōchū 2 (1325), Eiwa 2 (1376), Eitoku 2 (1382), and a run of Ōei years (5, 6, 12, 14, 22, 25). The shared hand the setsumei describe is an archaic northern one. The forging is itame mixed with mokume and nagare-hada, frequently with ō-itame, the grain standing up (hada-dachi) and at times an ayasugi-like or, near the edge, masame tendency; thick ji-nie gathers and bold chikei enter, the steel inclining to a blackish tone with a whitish cast, and shirake-utsuri rising in the ground. The temper is built on suguha and suguha-chō passing into ko-midare, or a shallow notare joined with ko-gunome and ko-notare; the habuchi shows frequent hotsure, kinsuji and sunagashi run vigorously, and a yaki-otoshi often drops the hardened edge at the machi.
The nioiguchi tends to shizumi and urumi, subdued and moist rather than bright, though certain pieces run brighter. The bōshi enters midare-komi or yakizume with hakikake, and the carvings, bonji over a sankō-tsuka-ken, are rustic yet carry an elegant taste. To recognize the hand, read the standing large-grained hada, the dark steel with whitish utsuri, and the quiet nioiguchi, set against the heroic koshizori tachi form. For kantei, the diagnostic cluster is the combination of standing ō-itame with bold chikei, blackish steel under whitish utsuri, yaki-otoshi at the base, and the subdued nioiguchi with hotsure, kinsuji, and sunagashi, the whole carrying a frankly provincial character that the setsumei treat as the lineage's signature. Signature study is itself a kantei tool: the two-character Hōju mei of the Eitoku-era tachi recorded in Honma's inventory of the Imperial collection is read against an orikaeshi-mei example dated Eitoku, certified an Important Art Object, to date later works by the same chisel. Named survivors map the standing: two signed tachi recorded in Honma's inventory of the Imperial collection, the kinzōgan-mei katana carrying a Hon'ami Kōchū origami of Kyōhō 7 (1722), the Shōchū 2 tachi held by Mitake Shrine, and an ubu mumei ōdachi transmitted as a hereditary treasure of the Murakami, the maritime warriors of the Seto Inland Sea. Ubu, signed, and dated Hōju, especially those not descending past early Nanbokuchō, the setsumei prize as reference material for an Ōshū tradition otherwise known largely through this one enduring name.

Two courts, sixty years of war, and the most dramatic silhouettes in the sword’s history: broad blades, extended points, true ōdachi later cut down into the majestic katana collectors prize. The Sōshū manner was the style of the age.
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.
