The Toryusai school was established in Edo by Tanaka Seiju (1804--1876), born the son of the Musashi Province tsuba maker Tanaka Fusajiro. Seiju trained formally under Goto Sojiro Masanori but pursued the broader field of kinko largely through self-directed study, ultimately perfecting a stylish, distinctive personal manner that became known as the Toryusai style. Counted among the "three great masters of Bakumatsu metalwork," he rivaled the fame of Goto Ichijo in Kyoto and, like Ichijo, was granted the rank of Hogen. Learn more →
