Ainu Languages: Diversity and Endangerment

The Ainu people, indigenous to northern Japan and parts of Russia, historically spoke several distinct languages within the Ainu language family, which is a language isolate. The main varieties include:

• Ainu Munen (Iomante): Widest spoken, in Hokkaido and Sakhalin, with several dialects.
• Sakhalin Ainu: Spoken on Sakhalin Island, with North and South dialects.
• Kuril Ainu: Once spoken in the Kuril Islands, now extinct.
• Hokkaido Ainu: Spoken in Hokkaido, Japan.
• Hidaka Ainu: Critically endangered, few elderly speakers remain.

While sharing grammar and vocabulary, dialects differ in pronunciation. Assimilation policies have led to severe decline; revitalization efforts are underway.
