Island chain (pop., 2000 prelim.: 1,329,000), Japan.
It extends in an arc 600 mi (970 km) long from southern Japan to the northern tip of Taiwan. The 55 islands and islets have a total land area of 871 sq mi (2,255 sq km). In ancient times it was an independent kingdom, but Chinese and Japanese sovereignty were successively imposed on the archipelago from the 14th to the 19th century. In 1879 the Ryukyus became an integral part of Japan. After Japan's defeat in World War II, the U.S. took control of the islands; it returned them all by 1972. The U.S. maintains military bases on Okinawa . The islands are primarily rural, and agriculture is the dominant occupation.
