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.

The islands have been recognised as an Important Bird Area (IBA) by BirdLife International because they support populations of Japanese wood pigeons and Pleske's grasshopper warblers.^[3]

The cruise course visiting many scenic coastal rocks and islets is available from Shimo-Koshiki island.^[4]
