Ryūkyū-Sprachen
In addition to the Japanese language, Ryukyuan languages are spoken in Okinawa and parts of Kagoshima in the Ryukyu Islands. Along with Japanese, these languages are part of the Japonic language family, but they are separate languages, and are not mutually intelligible with Japanese, or with each other. All of the spoken Ryukyuan languages are classified by UNESCO as endangered.
