アイヌ語 is the language of the アイヌ people, an indigenous group primarily found in 北海道 (Hokkaido), Japan, and parts of サハリン (Sakhalin) and the 千島列島 (Kuril Islands). It is considered a language isolate, meaning it has no known relation to other languages. The language has faced decline due to historical pressures and assimilation policies. Efforts are being made to revitalize アイヌ語 through education and cultural programs, aiming to preserve the unique heritage of the アイヌ people and promote their linguistic identity.
