The Dōtanuki (同田貫) line took shape in Kikuchi District of Higo Province toward the close of the Muromachi period and carried its activity forward into the shintō era, spanning the Momoyama transition into early Edo. The setsumei of the group's own blades name several of its hands: Ueno no Suke, whose dated work runs from Tenshō through Keichō and who is therefore described as a maker active across the divide between old and new traditions; Fujiwara Masakuni, treated as a leading smith of the school; Masahiro, whose naginata the register notes is absent from the meikan and so supplements that omission; and Matahachi. The accounts further list Samanosuke, Hyōbu, Matahachizaemon, and Kunikatsu among the line's signing smiths. The group is repeatedly framed as a representative Kyūshū lineage of the period, working in the domain that would become the ground of Higo's later military culture. The shared vocabulary of the setsumei is plain and consistent. The sugata is described as sturdy and uncompromising, bukotsu, with wide mihaba, thick kasane, and ample hiraniku, and little difference between base and tip width; on swords the sakizori can be pronounced and the chū-kissaki extended, while the spears and large naginata show flaring, full heads. The kitae is itame, often with nagare and mokume mixed in and a tendency toward hada-dachi, with ji-nie adhering and chikei at times visible.
The hamon moves between two registers: a notare base mixed with ko-gunome, ko-chōji, and ko-togariba, and a quieter suguha with ko-ashi and yō; across both the nioiguchi tends to be tight, nie gathers densely, and sunagashi, kinsuji, tobiyaki, and muneyaki recur. The hand is recognized by this combination of robust unrefined build and a midareba whose tight nioiguchi and clustered nie read as rustic rather than ornamental. The register notes a shizumi-gokoro, a subdued tendency in both ji and ha, that lends a restrained austerity. " The setsumei return again and again to cutting power: the sharpness of these blades is highly praised, and they are recorded as practical weapons carried into use. Provenance survives in mounted form, including a naginata by Masakuni accompanied by a black lacquer mounting with gold maki-e judged contemporary with the blade, and a Matahachi naginata with its black-lacquered pole mounting. Within the line, individual works are singled out as superior examples that convey the school's character, the Ueno no Suke katana of Keichō 16 being read as exceptionally fine among its peers. The register places Dōtanuki as a Higo lineage whose unadorned strength and cutting reputation hold a recognized standing in the shintō-period record. Learn more →

The Edo period (1615 to 1868)
Under the Tokugawa peace the daishō became a regulated uniform, and demand gathered in the castle towns, above all Edo itself. The craft split two ways: brilliant display work for connoisseurs, and tested blades whose cutting results were sometimes inlaid in gold.
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.
