The Ainu , also referred as Ezo in historical texts , is the indigenous groups in Japan. Historically they spoke the Ainu language and lived in Hokkaido, the Kuril Islands, and much of Sakhalin. Most of The Ainu still lives in the same region, though the exact number of living Ainu is unknown. This is due to some ethnic issues in Japan resulting in those with Ainu backgrounds hiding their identities and confusion over mixed heritages.
