Perry’s arrival in 1853 unraveled the Tokugawa peace and created the first mass demand for working swords in two centuries. Kiyomaro, called the Masamune of Yotsuya, died on its eve; Munetsugu and Yukihide carried the boom to the end.
This katana by Yamakimi Seimon Shokuzō Moritoshi from Suō province is dated 1860 (Ansei era) and is certified as NBTHK Tokubetsu Hozon. It features a standard shape with deep curvature, an elongated kissaki, and a fine ko-itame hada. The blade comes with a koshirae including a Chōshū-jū Tomokata signed tsuba and shakudo fittings.
Certificate reading — 銘 山君青門嘱造盛俊(周防)安政庚申仲春下浣
