| This uchigatana was attributed to the “Shitahara” school.The Shitahara smiths were a group of swordsmiths active in Musashi Province, around present-day Hachiōji, who inherited techniques of the Sōshū tradition. During the Sengoku period they worked under the patronage of the Hōjō clan, and in the Edo period they prospered as official swordsmiths of the Tokugawa shogunate until the end of the Edo era.The workmanship of the Shitahara school resembles the Odawara Sōshū tradition, and some of their better works can easily be mistaken for high-quality Sōshū-den blades. The school is also known for a distinctive jihada called “Jorin-mokuhada,” in which mokume grain appears repeatedly in wheel-like patterns.From the characteristics of the jihada and hamon, together with its highly practical sugata, this blade is considered to be a Sue-koto work. The characteristic Jorin-mokuhada associated with the Shitahara school can be observed, making the attribution appropriate.The sword is accompanied by an Edo-period tachi koshirae with a black leather-covered lower scabbard and an unusual lacquer finish.Passed the 2025 Hozon Token shinsa. |
