Tsudaka

Tsudaka lay in western Bizen, where Kanagawa commanded routes through the hills north of Okayama. Kanagawa Castle was the stronghold of the Matsuda, a warrior family whose power extended across western Bizen. In 1568 Ukita Naoie captured the castle and destroyed the Matsuda's rule. The castle was eventually abandoned under the shogunate's order limiting each province to one castle; the road through Kanagawa later linked Okayama with Tsuyama.
