The Shimizu school is one of the four mainline houses -- together with Hayashi, Hirata, and Nishigaki -- that represent the orthodox tradition of Higo kinko (肥後金工). Its founder, the first-generation Shimizu Jinbei, is traditionally said to have been a nephew of Hirata Hikozo, and to have studied under him.
