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 is a tachi by Miyairi Kiyohira, born Miyairi Eizo, who was the younger brother of Living National Treasure Miyairi Akihira (later Yukihira). Made in 1988 when the smith was 64 years old, it features a wide body, thick kasane, and large kissaki, with a vibrant jigane and bright hamon in the Soshu tradition, influenced by Gen Kiyomaro.
