The Ryukyuan languages are linguistically positioned as a dialect that divides Japanese into two. The Ryukyuan languages are further divided into several regional languages within them, and are highly diverse languages that may lack mutual intelligibility among regional languages. Today, the daily use and succession of The Ryukyuan languages has become difficult, and some of the Ryukyuan languages are on the verge of extinction. By the time we reached this point, the introduction of the Ryukyu Kingdom into the “modern state of Japan” triggered by the disposition of Ryukyu, the rise of Japan's expansionist policies and militarism, ground battles in the Pacific War. In this flow, the Ryukyuan languages have always been the objects of correction, sometimes as obstacles to the modernization of Ryukyu, sometimes as obstacles to the training of the powerful Imperial Army, sometimes symbolizing the backwardness or barbarity of the Ryukyuan people. In the 1990s, the “Okinawa boom” occurred in Japanese society, and in conjunction with this boom, the Okinawa government has actively re-evaluated Okinawa's history, culture and society, mainly among young people. At this point, for the first time since modern times, the Ryukyuan languages have been removed from their position as a subject of exclusion. In order to maintain the diversity that the Ryukyuan languages originally have, it is necessary for the community to raise their voices. In this regard, the voluntary movement toward the reconstruction of regional languages in the surrounding islands of the Ryukyu Islands is a notable example.
