Every article about Hokkaido written by Western scholars are outdated or tend to have this historical misconception about the Ainu being indigenous to Hokkaido, such as this BBC piece. The Ainu are not indigenous to Hokkaido. The only factually known indigenous people of Hokkaido as well as the whole of the Japanese archipelago is the Jomon, as far as current evidence is considered. The Jomon lived in Hokkaido centuries before the Ainu existed. Recent DNA studies have found that the Ainu in the Edo era was already an admixture of Jomon, Okhotsk and about 30% mainland Japanese. I also noticed that Western scholars usually get very defensive when we show them evidence that their narrative of Ainu being the indigenous victims of Japanese colonization is false.
