There remain numerous Ryukyuan languages which are more-or-less incomprehensible to Japanese speakers. These languages are in decline as the Mainland Japanese is being used by the younger generation. Many linguists, at least those outside Japan, consider Ryukyuan languages as different languages from Japanese, while they are generally perceived as “dialects” by mainland Japanese and Okinawans themselves. Standard Japanese is almost always used in formal situations. In informal situations, de facto everyday language among Okinawans under age 60 is okinawa-accented mainland Japanese called ウチナーヤマトグチ (Uchinā Yamatoguchi “Okinawan Japanese”), which is often misunderstood as Okinawan language proper, ウチナーグチ (Uchināguchi “Okinawan language”). Uchināguchi still is used in traditional cultural activities, such as folk music, or folk dance. There is a radio news program in the language as well.
