NihontoWatchNihontoWatchWe are proud to present this splendid tanto equipped with Aikuchi koshirae crafted during the Koto period. The blade is in excellent condition, thoroughly polished and in very sound shape. The jigane features a mixture of itame and masame, with the yubashiri clearly visible. The hamon exhibits a dynamic finish, characterized by a hitatsura-style pattern with prominent gunome in the niedeki, along with prominent tama and tobi-yaki. The nakago is inscribed with the name Soshu Yasuharu. Yasuharu was a swordsmith exclusive to the Hojo family of Soshu, active in the late Muromachi period. Invited by Hojo Ujiyasu of Odawara, he relocated from Suruga Province to Sagami Province, Odawara, and took the character “Yasu” from Ujiyasu's name, adopting the name Yasuharu. The koshirae features a dasizame-style tsuka, with gyoyo mon applied to the fuchigashira. The saya is finished in a deep red wakasa lacquer, giving it an elegant and dignified appearance. This is your chance to own an exquisite tanto, likely once owned by a daimyo. Don't miss this opportunity.

When the great Kamakura masters had passed and the country slid into the wars of the late Muromachi, a residual Soshu-den held on in Sagami under a new patron. The Later Hojo, ruling from Odawara castle, kept smiths at hand, and it was from this orbit that the leading name of the window emerged: Tsunahiro, transmitted as a retained smith of the Odawara Hojo who took the character tsuna from Hojo Ujitsuna. The first generation's earliest dated works fall in the Tenbun era, and the line runs forward in the conventional reckoning through Tensho, Keicho, Kan'ei, and Manji, the third generation drawn west to Tsugaru by Tamenobu to forge daisho before returning home. Around him stood a wider Sagami population working the same idiom: Hirotsugu of Kamakura, whose strongest hands cluster near the Meio and Tenbun years; Hiromasa and Soso, names carried across several indistinct generations; Masahiro, reaching back toward Joji; and the Odawara group of Yasuharu, Yasukuni, and Fusamune, the last praised above all for his carving. These smiths inherited the manner of the Nanbokucho apex at a remove of generations rather than by direct descent from the mainline of Masamune and Sadamune. The signature of the phase is the open declaration of the full temper. The forging stays itame mixed with mokume, the grain inclined to stand (hadadachi-gokoro), with ji-nie and chikei; over it the smiths ran a notare-and-gunome ground that climbs the upper half into hitatsura, tobiyaki and muneyaki firing across ji and mune, sunagashi and kinsuji threading the ha. This is the hitatsura and o-midare learned from Hiromitsu and Akihiro, but pushed toward display: the Hirotsugu katana of the 61st Juyo runs its temper so high it reaches the shinogi, mixing choji, togariba, and yahazu-gata into a demonstrative yakidaka pattern.
The contrast with the classic apex is precise and the appraisers mark it. Where Masamune raised nie to its deepest refinement over a bright, clear steel, the Sue-Soshu ji tends to shirake, a whitish cast standing in for that clarity, and the nioiguchi inclines to shizumi, a sunken or subdued quality rather than depth. The 238th Jubi record states the point plainly for the first-generation Tsunahiro: the ji and ha carry abundant nie, yet the very shape of the hamon departs from that of Hiromitsu and Akihiro. The temper is broader and busier across the surface, but it lacks the quiet command and the leaping interior activity of the original. To kantei the window is to separate this demonstrative late temper from the classic Soshu-den it imitates: a standing itame with shirake, a wide hitatsura worked with yahazu and crescent tobiyaki, a nioiguchi that sinks rather than deepens, and signatures reading Soshu-ju with full given names rather than the o-suriage mumei of the great forebears. The named hands carry the distinctions, Fusamune through his dense, precise horimono of kurikara and bonji, Tsunahiro through his crescent tobiyaki and high monouchi fire, Hirotsugu through a hitatsura vigorous enough to recall Hasebe. Provenance keeps these blades close to power: several are recorded in Honma's inventory of the Imperial collection, one bearing the ownership inscription of Akimoto Yoshihide of Kozuke, another the Hachiman Daibosatsu invocation of a Sengoku warrior, the Tsunahiro commission tied by its dated nakago to the Tsugaru house.
