Shakushain's revolt
Hokkaido, JapanShakushain's revolt was an Ainu rebellion against Japanese authority on Hokkaidō between 1669 and 1672. It was led by Ainu chieftain Shakushain against the Matsumae clan, who represented Japanese trading and governmental interests in the area of Hokkaidō then controlled by the Japanese (Yamato people).
The war began as a fight for resources between Shakushain's people and a rival Ainu clan in the Shibuchari River (Shizunai River) basin of what is now Shinhidaka, Hokkaidō. The war developed into a last try by the Ainu to keep their political independence and regain control over the terms of their trade relations with the Yamato people.
