Ko-Uda (古宇多) names the founding stratum of the Uda school, the work that does not descend later than the Nanbokucho period and so stands before the long Muromachi continuation that the same studio names would carry. The setsumei place the origin in Yamato: around the Bunpo era at the close of Kamakura, the monk-smith Ko-nyudo Kunimitsu left Uda District in Yamato and settled at Utsu in Etchu, and from him the lineage took root.
