This is an unsigned Japanese katana with a blade length of 60.2 cm and a gentle curvature of 1.0 cm. The overall sugata is well-proportioned, typical of Shintō period swords intended for practical use as uchigatana.
The blade displays a notare (gentle undulating) hamon with visible nie along the temper line, giving the edge a bright and lively appearance. The jihada is a fine nashiji-like ko-itame, tightly forged and evenly patterned, reflecting careful workmanship and refined steel. This combination of a soft notare hamon with visible nie and a fine, dense hada is characteristic of blades influenced by the Osaka Shintō tradition.
Based on the blade’s proportions, forging style, and hamon characteristics, the sword can reasonably be attributed to the early Edo period (17th century), within the stylistic sphere of the Osaka Shintō school, which produced some of the most refined blades of the Shintō era.
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.
