After the defeat in the Battle of Shakushain, the Matsumae clan's control over the Ainu people was further strengthened, and especially after the establishment of the basho-contract system during the Genroku and Kyoho periods (1688-1736), the Ainu people were transformed from trading partners into laborers in the fishing grounds. However, the relationship between the Ainu people of the so-called "Oku-Ezo region," such as Akkeshi (Akkeshi), Kitappu (Kiritappu), and Kunashiri, and the Matsumae clan was somewhat different.
