Regarding the request to retract the relocation plan to Henoko to protect the dugongs in Okinawa

The Okinawa Prefectural Government sent a request to the U.S. government in April, 2018, to have discussions with the Okinawa Prefectural Government and other stakeholders as required by the National Historic Preservation Act. The discussions would enable the U.S. government to give proper deliberation to the cultural significance of dugongs and the impact the plan has on them.

However, the construction work began without any discussions between the Department of Defense and the Okinawa Prefectural Government taking place. Also, a dead dugong was found in the waters of the northern part of the mainland of Okinawa. Therefore, we have sent a letter to three members of the U.S. government including the Secretary of Defense to request the U.S. government to retract the relocation plan to Henoko to protect the dugongs.

U.S. Military Base in Okinawa

Okinawa Prefectural Government regards the Japan-U.S. alliance as vital. However, we have a concentration of 73.9% of the exclusive use facilities and areas of U.S. Forces in Japan in a land area that is no more than 0.6% of the national land area. Therefore, it is necessary to reduce and consolidate U.S. military bases in Okinawa.

With the realization of land returns of U.S. military bases south of Kadena Air Base, we can anticipate positive economic and employment impacts through effective land use.

Establish the prefecture as a hub of exchange by taking advantage of our geographical location, to bridge people, goods, and information between mainland Japan and other Asian nations. It is our desire to actively promote international contribution and do our part for peace and advancement of the Asia-Pacific region.
