Waga
Waga lies west of the Kitakami River, where mountain streams enter the broad valley of northern Mutsu. The Waga family lost its lands in Toyotomi Hideyoshi's settlement of 1590, and the Nanbu took possession. In 1600 Waga Tadachika rose with support from Date Masamune and attacked Hanamaki Castle. The assault failed, and after holding out at Iwasaki Castle his forces were defeated the following year.
