This is a Katana attributed to Osafune Morishige, a smith from the Eikyo era (1429). It features a well-proportioned shape with deep curvature and an extended kissaki, showcasing a beautiful jigane with utsuri and a hamon reminiscent of the Ichimonji school. The blade comes with both a shirasaya and a koshirae, and is accompanied by an NBTHK Tokubetsu Hozon Token certificate.

The published sources follow the line back to a remote ancestor, Kunimori, who is said to have left Inokuma Omiya in Yamashiro province and moved into Bizen during the Kamakura period, around the Bun'o years. With him the group carried a Yamashiro sensibility into the province of choji, and that transplanted origin remains the key to everything the school later became. Learn more →
