Within the long span of Naminohira, Ko-Naminohira (古波平) marks the formative chapter, the body of smiths and works held in the setsumei to not descend past the Nanbokuchō period. The setsumei place the school's base at Naminohira in Taniyama District of Satsuma Province in southern Kyushu, where, by tradition, a Yamato smith named Masakuni settled in the late Heian era around Eien (987 to 989) and founded the line.
