This unsigned Japanese katana measures 61.2 cm (24.1 in.) in blade length with a restrained 1.0 cm sori. The blade has undergone suriage (shortening), and the nakago retains three mekugi-ana, indicating that it was remounted and adapted several times during its long history.
The relatively shallow curvature and overall proportions are consistent with a late Muromachi-period sword, likely dating from the late 15th to 16th century. The extensive shortening and multiple mekugi-ana further reflect the continued use and changing mounting traditions of the blade over the centuries.
The sword is mounted in Type 98 guntō koshirae with a leather-covered scabbard, typical of field-service mounts. The remounting of traditionally forged blades into military fittings was common during the wartime period, reflecting continued functional use.
