History
The islands once consisted of 14 villages, belonging to Shikijima-gun, Satsuma Province (Satsuma no Kuni) during the Meiji period. In 1889, the islands were consolidated into Kami-Koshiki and Shimo-Koshiki villages. In 1897, the islands were merged with Satsuma-gun. Later, Kashima village and Sato village broke off, for a total of four villages. In 2004, during "the great Heisei merger", the villages were merged with the city of Sendai, on the coast of Kyushu.
