This is a koto katana certified NBTHK Hozon and attributed to the Shitahara group of Bushu (Musashi). The blade measures 62.27 cm in nagasa with a gentle 0.76 cm sori, presenting a dignified shinogi-zukuri profile and a well-forged jihada. Shitahara blades often show steady forging with Sōshū–Mino influences, and a hallmark to watch for is jorinmoku—small whirlpool-like figures in the steel surface.

The Shitahara group (下原) worked at Hachiōji in Bushū, the old province of Musashi, from the end of the Muromachi period and carried its forge on into the Edo period. The setsumei place the lineage among the swordmakers of Musashi in the kotō age and name Terushige, Yasushige, Hiroshige, and Chikashige as its leading hands, with the meikan recording Terushige across three generations: a shodai in Kyōroku, a nidai in Eiroku, and a sandai in Tenshō.
