Yamashiro Katashi

Yamashiro Katashi, also recorded as Minamoto no Tsubura, was an early Kamakura warrior and the third son of Yamashiro Kakoi, founder of the Hizen Yamashiro.

After the Jōkyū War of 1221 he married a daughter of the Kamachi family of Chikugo Province and received its lands, becoming the ancestor of the Kamachi clan. He had no son of his own. The Yamashiro house therefore passed to his nephew and adopted heir Hiroshi.
