An unsigned Japanese katana from the Shōwa period, measuring 60.1 cm in nagasa with a sori of 1.8 cm.

The blade features a striking, undulating midare hamon with a bold and clearly visible temper pattern. Shōwa-era Japanese swords have attracted increasing appreciation among collectors in recent years, particularly for their distinctive hamon, robust construction, and practical cutting characteristics.

The sword is mounted in Type 98 guntō koshirae with a leather-covered scabbard, typical of field-service mounts.

An appealing example for collectors interested in Japanese military-era craftsmanship.
