  ## History
  
  Kogajajima does not appear to have ever had permanent human habitation.
  
  During the Ryukyu Kingdom era, the territory of the kingdom reached as far as Kogajajima island.
  
  During the Edo period, Kogajajima was part of Satsuma Domain and was administered as part of Kawabe District. In 1896, the island was transferred to the administrative control of Ōshima District, Kagoshima, and from 1911 was administered as part of the village of Toshima, Kagoshima. From 1946 to 1952, the island was administered by the United States as part of the Provisional Government of Northern Ryukyu Islands.
