Mizawa
The Mizawa were local lords of Izumo Province, based at Mizawa Castle and controlling iron-producing lands. In 1391 Mizawa Tametada died fighting for the Yamana in the Meitoku rebellion.
Mizawa Tamekiyo entered Mōri service in 1562 and helped defeat an Amago restoration army at Nunobeyama in 1570. His son Tametora was confined by Mōri Terumoto in 1589, but was later released and became a senior retainer of the Chōfu domain.
