At that time, Bizen was the territory of Akamatsu Masanori, who had regained power during the Onin no Ran; Ukyo no Suke Katsumitsu and Sakyo no Shin Munemitsu sometimes served in the Akamatsu army, and during the ninth Shogun Yoshihisa's attack on the Rokkaku of Omi, they went to the Magari no Jin in Omi with their entire clan by order of the Akamatsu clan to perform gozen-uchi for the Shogun. Arimitsu was of the same clan and school as Katsumitsu and Munemitsu and likely swung the hammer to assist them; saku with his own mei are extremely rare.

The Soden Bizen school encompasses the group of Nanbokucho-period Osafune smiths in Bizen Province whose work absorbed the technical influence of the Soshu-den, producing a distinctive synthesis that stands apart from both orthodox Bizen and pure Sagami practice. The school divides into two principal lineages: the Kanemitsu group, representing the direct main line of Osafune that descends from Mitsutada through Nagamitsu and Kagemitsu; and the Chogi group, a collateral branch whose members carried the Soshu idiom to its most expressive extremes within Bizen. Kanemitsu, the chakuryu heir of Kagemitsu, pioneered the broad, relaxed notare-based midare that defines the mature Nanbokucho Osafune manner, while Chogi -- described by the NBTHK as the smith "who departs furthest from Bizen" among Bizen makers -- pushed nie-dominant forging to a level that rivals the output of the great Sagami smiths themselves. Together with disciples and contemporaries including Tomomitsu, Motomitsu, Masamitsu, Yoshimitsu, Kanenaga, Nagashige, and Nagamori, they constitute one of the most prolific and technically accomplished groups in the history of Japanese swordsmithing. The school's collective technical identity is anchored in a shared jigane of itame-hada mixed with mokume, with fine ji-nie adhering thickly, chikei entering well, and midare-utsuri standing out -- a persistent Bizen hallmark that survives even in the most Soshu-inflected work. The sugata overwhelmingly reflects the grand Nanbokucho taihai: wide mihaba with little taper between base and tip, and an extended chu-kissaki or o-kissaki conveying martial vigor. Within this shared framework, two distinct temperaments emerge.
" Yoshimitsu likewise inherits the small-pattern tendency, producing ko-gunome mixed with ko-choji whose restraint the NBTHK praises as "upper rank" Soden Bizen. The Chogi lineage, by contrast, emphasizes powerful nie in both ji and ha: Chogi's flamboyant large-scale midare weaves together gunome, choji, togariba, and koshi-hiraki forms with tobiyaki and yubashiri scattering freely, while kinsuji and sunagashi streak through the hardened edge. " Nagashige, now thought to be Chogi's elder brother rather than his junior, works a gentler, smaller-patterned midare yet with nie so strong as to "even surpass Chogi," while Nagamori occupies an intermediate position, his "somewhat smaller patterning" accompanied by rich internal activity. The historical significance of the Soden Bizen school lies in its demonstration that the Soshu influence, far from merely displacing Bizen conventions, catalyzed an extraordinary expansion of the Osafune repertoire. " The NBTHK's evaluative language across the school converges on consistent themes: the forging is "meticulous" and "excellent-quality," the nioiguchi "bright and clear," and the finest examples display a kenzen condition that attests to the soundness of Bizen steel at its peak. The abundance of dated inscriptions -- from Kanemitsu's forty-five-year span through Masamitsu's four-decade career extending into the early Muromachi period -- provides an unusually well-documented chronological framework, with later works by Masamitsu and Yoshimitsu pointing toward the subsequent development of Oei Bizen. Within the broader canon, the Soden Bizen school stands as the fullest realization of the creative possibilities that emerged when two of Japan's greatest forging traditions met and merged.

Bizen in the Muromachi period
War at home and trade abroad made Muromachi Bizen the busiest forge region in Japan: a century of Sengoku demand after the Ōnin War, and export missions to Ming China carrying blades by the tens of thousands.
A Hozon-certified blade judged to show notably superior workmanship and a better state of preservation. The bar is higher: re-tempered blades and most unsigned Muromachi/Edo works are excluded.
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.
