宮古群島
Miyako District was formally established in 1896, and spanned all of the Miyako Islands, which are located approximately west of the prefectural capital of Naha. Miyako Island served as the administrative center of the district. In the administrative reforms of 1908 the former magiri administrative system was abolished, and Miyako District was divided into four villages: Hirara, Shimoji, Gusukube, and Irabu. In 1913 the localities of Nakasuji, Shiokawa, and Minna were separated from Hirara Village to form a fifth village, Tarama. Hirara was elevated to town status in 1924.
