The Naminohira school traces its origins to the late Heian period, when a swordsmith named Masakuni migrated from Yamato Province and established himself at Naminohira in Taniyama District, Satsuma Province. His son Yukiyasu succeeded him, and the lineage continued unbroken into the late Edo shinshintō era. The collective term Ko-Naminohira designates smiths and works dating no later than the Nanbokuchō period, distinguishing the school's formative generations from later practitioners. Learn more →
