The Omiya school (大宮) of Bizen traces its name and its blood to Kyoto, not to the Bizen heartland where it eventually settled. The published sources follow the line back to a remote ancestor, Kunimori, who is said to have left Inokuma Omiya in Yamashiro province and moved into Bizen during the Kamakura period, around the Bun'o years. With him the group carried a Yamashiro sensibility into the province of choji, and that transplanted origin remains the key to everything the school later became. Learn more →
