Koyama Motohiro was the finest swordsmith of the Nihonmatsu Domain, having trained under Kunisada in Sendai and further honing his skills in Edo under Suishinshi Masahide. The Touryusai school traces its origins to Kiyotoshi Tanaka, who was born in Aizu in the first year of the Bunka era and is said to have trained in the Aizu Shōami school during his youth. He honed his skills under Kōno Shunmei when the latter visited Tōhoku, completing a clever style known as the Touryusai school that became popular during the late Edo period. This tsuba is a collaboration between a swordsmith and a metalworker, making it a rare piece.
