The Bizen Unrui school is thought to have derived from migrants from Kyoto in the late Kamakura period. Unsho and the following generation, Unji, were once thought to have originally been the smiths Kunitomo and Kuniyoshi. In some respects their blades are reminiscent of the Rai school of Yamashiro, and, as might be expected, share similarities with contemporary neighbouring groups in Bizen and Bitchu.
