Mageshima

Hayama (葉山), Ou Komori (王籠), Takabo (高坊), Kakise (垣瀬), Shiinoki (椎ノ木).

Mageshima has been occupied, at least seasonally, since the Kamakura period (1185–1333 CE), as fishermen from neighboring Tanegashima would use it as a base of operations.

Initial logging to clear an area for the proposed runways was performed without proper permission, and in September 2011 local fishermen filed lawsuits alleging damage to fishing grounds due to increased runoff created by the illegal logging.

In November 2019, the Government of Japan made an agreement with the Tokyo-based development company Taston Airport to purchase Mageshima for 16 billion yen ($146 million).

[1] Japanese Chief Cabinet Secretary Yoshihide Suga said "purchase of Mageshima Island is extremely important and serves for strengthening deterrence by the Japan-US alliance as well as Japan's defense capability".

[4] On November 29, 2022, Kagoshima's governor Koichi Shiota agreed to the construction of the base citing the "increasingly severe security environment" surrounding Japan.
