context_page_description: The Ainu or the Aynu, also known as the Ezo in historical Japanese texts, are an East Asian ethnic group indigenous to Japan, the original inhabitants of Hokkaidō and Russia.
  Official estimates place the total Ainu population of Japan at 25,000. Unofficial estimates place the total population at 200,000 or higher, as the near-total assimilation of the Ainu into Japanese society has resulted in many individuals with Ainu heritage having no knowledge of their ancestry.
context_section_description: The traditional locations of the Ainu are Hokkaido, Sakhalin, the Kuril Islands, Kamchatka, and the northern Tohoku region. Many of the place names that remain in Hokkaido and the Kuril Islands have a phonetic equivalent of the Ainu place names.
  In 1756 CE, Mitsugu Nyui was a kanjō-bugyō (a high-ranking Edo period official responsible for finance) of the Hirosaki Domain in the Tsugaru Peninsula. He implemented an assimilation policy for Ainu who were engaged in fishing in the Tsugaru Peninsula. Since then, Ainu culture was rapidly lost from Honshu.
  After the Treaty of Saint Petersburg (1875), most of the Ainu from the Kuril islands were moved to the island Shikotan by persuading the pioneers for difficult life supplies and for defense purposes (Kurishima Cruise Diary).
  In 1945, the Soviet Union invaded Japan and occupied Sakhalin and the Kuril Islands. The Ainu who lived there were repatriated to their home country, Japan, except for those who indicated their willingness to remain.
