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 made by Miyairi Kiyohira in Shinano province during the Showa period. Kiyohira, whose real name was Miyairi Eizo, was the younger brother of the Living National Treasure Miyairi Kohei. He studied under his brother and specialized in the style of Kiyomaro. This particular piece is a long blade that emulates the style of Kiyomaro.
