Ōsumi Islands
In 1879, the Amami Islands became Ōshima District of Kagoshima Prefecture. The Tokara Islands and the north-western group of the Ōsumi Islands were transferred to Ōshima District in 1897, and then to Kagoshima District in 1973. After World War II, the Tokara and Amami Islands were put under United States military occupation, which formed the Government of the Northern Ryukyus. The Japanese government fiercely contested the Amami Islands being affiliated with the word "Ryukyu", believing that it would lead to a later return of the islands to their control. The Tokara Islands were returned to Japan in 1952, which were followed by the Amami Islands in December 1953.
