Tanto - Jumyo - Shirasaya Koshirae - Ubu Nakago - Shinto Era - Ibaraki 18202

This is a well-preserved tantō made around the mid-Edo period.

The blade is uniformly sharpened throughout with no flaws, exhibiting excellent preservation. The jigane displays a well-kneaded itame grain pattern, with lively yubashiri also visible. The hamon exhibits completely different expressions on the sashimote  and sashiura sides. The sashimote side features a dynamic, sakasa-choji-style hamon with deep, pronounced nioi. Conversely, the sashiura side's hamon is a gentle, flowing notare pattern, occasionally interspersed with slightly lower-headed gunome, giving it a very serene impression. The nakago is inscribed with “Bishu Ju Jumyo.”

He was a renowned swordsmith active in Owari Province (present-day Aichi Prefecture), from a prestigious lineage whose name was passed down until the Bakumatsu period. Initially based in Noshu (present-day Gifu Prefecture), he later relocated to Owari and other regions where he flourished. The name Jumyo is a pun meaning “long life,” making blades bearing it highly auspicious. They were immensely popular among daimyo and samurai families, treasured as gifts or ceremonial swords for coming-of-age ceremonies.
