Where Ko-Mihara closes at the end of the Nanbokuchō period, Sue-Mihara takes up the Bingo tradition through the Muromachi era. The setsumei place the later production in the same Mihara orbit but spread across several named hands and affiliated branches: Kai Mihara Masamori, whose Muromachi katana often carry the long "Mihara-jū Kai _" signature; and the closely tied Hokke Ichijō line, whose founder Ichijō is traditionally called a son of Mihara Masaie and whose generations continued from the Ōei era into the late Muromachi.
