The twentieth century nearly killed the craft twice: wartime distortion, then the occupation ban. The NBTHK’s founding in 1948 and licensed forging from 1953 rebuilt the sword as an art, crowned by Living National Treasures and the mukansa rank.
This katana is signed by Miyairi Kozaemon Yukihira, born in Showa 32 (1957). He was the son of the Living National Treasure Miyairi Yukihira, who mastered the Soshu tradition. Though his father passed away before he could inherit all techniques, Kozaemon Yukihira continued his studies and research, eventually surpassing his predecessor in the Soshu tradition.
