Ainu is a language isolate historically spoken on Hokkaido and, in now-extinct dialects, on Sakhalin and the Kuril Islands, unrelated to Japanese or to any other known language family. Suppressed under Meiji-era assimilation policy, it survives today with only a handful of fully fluent native speakers and is classified by UNESCO as critically endangered, alongside ongoing revitalization efforts. This entry names Ainu's classification as a language isolate; the fuller linguistic and cultural treatment of Ainu already exists elsewhere in this database.
