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 listing is for a katana by Kasama Ikkan-sai Shigetsugu, dated to an auspicious day in August, Showa 12 (1937).
