Hachijō language

Japonic language

The small group of Hachijō dialects , natively called Shima Kotoba , depending on classification, either are the most divergent form of Japanese, or comprise a branch of Japonic. Hachijō is currently spoken on two of the Izu Islands south of Tokyo as well as on the Daitō Islands of Okinawa Prefecture, which were settled from Hachijō-jima in the Meiji period. It was also previously spoken on the island of Hachijō-kojima, which is now abandoned. Based on the criterion of mutual intelligibility, Hachijō may be considered a distinct Japonic language, rather than a dialect of Japanese.
