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 Shinano Kuni KiyoYuki in the Heisei era. KiyoYuki, whose real name is Furukawa Nobuo, studied under Miyairi Kiyohira and received authorization to forge swords from the Agency for Cultural Affairs in 1978. He won the Kanzan Prize at the New Swords Exhibition and was designated as an intangible cultural property of Suzaka City in 2007.
