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.
A daisho set by Kasama Ikkansai Shigetsugu, a renowned modern swordsmith known for his exceptional horimono. The katana was made in Showa 10 (1935) and the wakizashi in Showa 12 (1937), both featuring intricate carvings of Bishamon-ten and other Buddhist motifs. The set comes with a Tokubetsu Hozon certificate from the NBTHK.
