The Natives of Japan. The Ainu (アイヌ?), also called Aynu, Aino (アイノ), and in historical texts Ezo (蝦夷), are indigenous people or groups in Japan and Russia. Historically they spoke the Ainu language and related varieties and lived in Hokkaidō, the Kuril Islands, and much of Sakhalin. Most of those who identify themselves as Ainu still live in this same region, though the exact number of living Ainu is unknown. This is due to confusion over mixed heritages and to ethnic issues in Japan resulting in those with Ainu backgrounds hiding their identities. In Japan, because of intermarriage over many years with Japanese, the concept of a pure Ainu ethnic group is no longer feasible.3 Official estimates of the population are of around 25,000, while the unofficial number is upward of 200,000 people.1

Get the Ainus mug.
A near-extinct ethnic group almost fully assimilated into Japanese society.
The Ainu People are more slavic looking rather then Japanese.
Get the Ainu People mug.
An incredibly ugly guy who likes Heavenlee Duke. He has no penis because he is secretly a girl. Ainu likes to make dumb jokes that nobody but himself laughs at. He is a horrible gamer with no friends.
Ainu will get murdered soon.
