Yamashiro

The Yamashiro were a branch of the Matsuura warrior league, originating in Yamashiro in Hizen Province. In 1359 Yamashiro Hiroshi fought for the Northern Court under Shōni Yorihisa at the Battle of Chikugogawa.

In the sixteenth century Yamashiro Kiyoshi joined an unsuccessful attempt to restore the Shōni against the Ryūzōji. Toyotomi Hideyoshi confirmed Yamashiro Sadashi in his lands during the conquest of Kyushu, and the family later served the Nabeshima of Saga.
