Description
Overview
Nobuyoshi was a swordsmith based at Ryūmon estate in Yoshino district, Yamato Province (present-day Yoshino-gun, Nara Prefecture), traditionally linked to the Senjuin school of the Yamato tradition. No dated work by him survives; stylistic analysis places his active period around the Shōō era (1288-1293) or the Bunpō era (1317-1319). This tachi is regarded as the finest of his surviving works.
