Yamauchi Kazutoyo and clan lords

Yamauchi Kazutoyo (1545/1546–1605) was a warrior of the late Sengoku and early Edo periods who rose from a minor samurai background to become a trusted retainer of Oda Nobunaga and later Toyotomi Hideyoshi, and after the Battle of Sekigahara he was rewarded by Tokugawa Ieyasu with the Tosa domain on Shikoku, founding the Yamauchi clan's rule there. He and his successive clan lords are venerated in Kōchi and among descendant families as ancestral and domainal founders, honored at shrines such as Tosa Shrine for their role in establishing and governing the Tosa han through the Edo period. Veneration of Kazutoyo and the Yamauchi lords centers on their historical legacy as regional and family ancestors rather than on any specific supernatural function.
