During the 1945-52 US occupation of Japan, the Americans constructed military bases in Okinawa. In 1952, in exchange for an end to the occupation, Japan allowed the United States to retain control of the prefecture. Okinawa, which was initially colonised by Japan in the 1800s, remained under US administration until 1972, and throughout this period, the United States built additional military bases in the prefecture. Since 1972, Japan has administered Okinawa and has allowed US bases to remain there, in accordance with the 1960 US-Japan Security Treaty, which permits US bases in Japan.
Successive Japanese governments have argued that US bases in Okinawa enhance Japan’s security and have also allowed the bases in exchange for a US commitment to defend Japan from external attacks. As a result, unsurprisingly, Japanese governments have, at times, responded to the anti-base movement with repression, including jailing anti-base activists without trial.
Okinawa Women Act Against Military Violence (OWAAMV), a key feminist non-governmental organisation within the anti-base movement, has for decades conducted protests in response to cases of violence by US personnel against Okinawan women and girls. According to the organisation, from 1945-2011, 350 crimes, including sexual violence, were committed by US personnel against Okinawan women. Within Japan and around the world, OWAAMV has thus drawn attention to the gendered and harmful impacts of US bases in Okinawa alongside US militarism.
In response to anti-base protests following the 1995 gang rape of an Okinawan girl by a group of American servicemen, the United States pledged to close its Futenma base, located in a heavily populated urban area and widely opposed by locals. The US and Japanese governments agreed to create a new base near the remote town of Henoko to replace Futenma. However, anti-base protestors want Futenma closed and have opposed the proposed Henoko base, which would be partly built over coral reefs, on the grounds that it would cause pollution and encroach upon the habitats of numerous animals, particularly the endangered dugong. As a result, 26 years since the two countries announced their plan to create the base, it has only been partially constructed and, to the dismay of the anti-base movement, Futenma remains in use.
