The Ichimonji school (Ichimonji-ha) represents one of the two paramount traditions of Bizen Province swordmaking during the Kamakura period, flourishing alongside the Osafune lineage from the early thirteenth century through the Nanbokuchō era. The school's name derives from the practice of carving the character ichi (一, "one") onto the nakago, though signatures varied considerably—some blades bear only this single ideograph, others append an individual maker's name beneath it, and still others carry personal names alone.
