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 Imaizumi Toshimitsu, forged in 1959 (Showa 34), the year he was certified as an Important Intangible Cultural Property of Okayama Prefecture. It is a magnificent piece with a long nagasa, wide mihaba, thick kasane, deep koshi-zori, and an ikubi-kissaki. The jitetsu is tightly forged ko-itame with fine ji-nie, and the hamon features gunome with kawazu-ko-choji and juka-choji, showing deep nioi and bright nie.
