沖繩群島
In 1945, the Okinawa Advisory Council was established by order of the United States Armed Forces, to administer the Okinawa Islands, the prefecture office of which had been eliminated as a result of Battle of Okinawa. The surviving prefecture offices, including those of Miyako Subprefecture and Yaeyama Subprefecture, established their own independent administrations. On February 2, 1946, after the decision to partition Japan's territory south of the 30th parallel north, Ōshima Subprefecture (including the Amami Islands and Tokara Islands) separated from the jurisdiction of Kagoshima Prefecture and came under the command of the United States Military Government of the Ryukyu Islands. On August 4, 1950, after multiple reorganizations, the Government of the Okinawa Islands, Government of the Miyako Islands, Government of the Yaeyama Islands, and Government of the Amami Islands were established.
