The name Sōjōbō originates from Sōjōgatani, the valley at Mount Kurama near Kibune Shrine associated with the Shugenja. It is in this valley that Ushiwaka-maru trained with Sōjōbō in legend. Sōjōgatani means Bishop's valley or Bishop's vale. The name of this valley is derived from the ascetic Sōjō Ichiyen.
