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 is a katana made by Yokoyama Sukehiro of the Osafune school in Bizen province during the Shin-Shinto period. The blade features a prominent choji hamon and a long, healthy ubu nakago. It comes with a shirasaya and a gold-clad habaki.
