Well, it is a bit difficult to describe about Ainu – original ethnic group in north-east Japan. They had own land that occupied by Japan. Well now we say Japan and we have only one race which is not true. Actually most of ethnic groups are already mixed well, though we still have some ethnic groups. Ainu is still one of clear race in Hokkaido area. Japan occupied Ainu area (Hokkaido area) by Meiji government and they send a lot of people as called “Tondenhei”. Tondenhei means “soldier for develop rice field”. Why they need to be soldier – answer is easy. Ainu people decided to have a party of Ainu – which is very good idea. The population of pure Ainu is already very small number. They need to keep their culture in their area. I do not know it is good idea to create new country for them in Hokkaido area, though, they should keep enough privileges in Japan.
