宮古列島
There are three native languages on the islands; Miyako language on the Miyako Islands, Yonaguni language on Yonaguni, and Yaeyama language on the other Yaeyama Islands. All these languages belong to the Southern Ryukyuan branch of the Ryukyuan languages group, which in turn belong to the Japonic languages group. These languages are not mutually intelligible. As on Okinawa, therefore, standard Japanese language is used in formal situations, while Okinawan Japanese, that is, standard Japanese with native Ryukyuan words, pronunciation changes, etc. mixed in, is quite commonly used as well.
