Marine Corps Air Station Futenma The base includes a runway as well as extensive barracks , administrative and logistical facilities . The air station is tasked with operating a variety of fixed and rotary - wing aircraft in support of the III Marine Expeditionary Force . The base is also used as a United Nations air facility . History . Futenma Airfield was constructed by the US military following the Battle of Okinawa in 1945 . It was built partly on the ruins of the villages of Aragusuku , Ginowan , Kiyuna and Isa , and entirely over the village of Kamiyama and surrounding farmland . According to Ginowan City records , the joint population of what was then Ginowan Village ( now Ginowan City ) was 12 , 994 in 1944 . It was initially allocated for Eighth Air Force use to station B - 29 Superfortress strategic bombers in the planned Invasion of Japan . With the end of the war , the airfield became a United States Air Force Far East Air Force installation known as Futenma Air Base , and was used as a support airfield for the nearby Kadena Air Base , hosting fighter - interceptor squadrons as part of the air defense of the Ryukyu Islands . The base was transferred to the United States Navy on 30 June 1957 and was subsequently developed into a major United States Marine Corps air station . Location . MCAS Futenma is situated in the center of Ginowan City ( pop . 93 , 661 ) . The air station covers approximately , about one quarter of the area of Ginowan City , and includes a runway . Local concerns . Local residents are concerned over pollution and ground water and soil contamination caused by the base ' s activities . For example , retired Marine Lieutenant Colonel , Kris Roberts , told the " Japan Times " that his base maintenance team unearthed leaking barrels of Agent Orange at the base in 1981 . Due to its urban location , concerns surrounding training flights over residential areas causing noise , air pollution and endangering public safety have become controversial issues in Ginowan City . Safety concerns were intensified after the August 2004 crash of a Marine Corps CH - 53D transport helicopter into Okinawa International University . Three crew members were injured , but there were no injuries on the ground . Public concern with crime related to the presence of US military on Okinawa rose in 1995 when three American servicemembers raped a 12 - year - old Okinawan girl . In December 1996 , the Japanese and U . S . governments decided that the Futenma base should be relocated to an off - shore location in Henoko Bay in Nago , northern Okinawa . This was and remains a controversial decision , since the projected site involved construction on a coral reef and seagrass beds which are the habitat of the dugong , an endangered marine mammal protected under Japanese and U . S . law . In a referendum conducted later the same year , a vast majority ( over 80 % ) of Nago residents voted against the Henoko plan . However , shortly afterward , they elected a mayor who campaigned on a platform of accepting the new facility . In March , 2006 , a new mayor was elected on a similar platform , getting more votes than his two anti - relocation opponents combined . Even so , opinion remained divided between those who view the ' relocation ' plan as a recipe for development in the northern part of the island , and others who consider it more likely to lead to the destruction of what remains of Okinawa ' s sub - tropical forests and undegraded coastal reefs . Relocation plans . As of April 2012 , the fate of Futenma remains unresolved with the US insisting that Futenma be moved to a location within Okinawa while , Okinawans " fiercely oppose Futenma and believe the base should simply be closed and moved overseas or elsewhere in Japan , " according to Time Magazine The US and Japan have meanwhile delinked the relocation of Futenma from plans to decrease the number of Marines stationed on Okinawa , reaching a troop redeployment agreement in April 2012 , which might make room for a new Futenma agreement according to Al Jazeera ' s Asia - Pacific correspondent Harry Fawcett . Under the terms of the new U . S . - Japan agreement 5 , 000 U . S . Marines will be relocated to Guam and 4 , 000 U . S . Marines to other Pacific locations such as Hawaii or Australia , while some 10 , 000 Marines will remain on Okinawa . No timetable for the Marines redeployment has been announced , but the Washington Post reported that U . S . Marines would leave Futenma as soon as suitable facilities on Guam and elsewhere are ready . The relocation move is expected to cost 8 . 6 billion US Dollars and includes a $ 3 . 1bn cash commitment from Japan for the move to Guam as well as for developing joint training ranges on Guam and on Tinian and Pagan in the Commonwealth of the Northern Mariana Islands . The relocation plan has had a complex history . On 26 October 2005 , the governments of the United States and Japan agreed to move the relocation site for Futenma from the reef area off Henoko to the interior and coastal portions of the existing Marine infantry base at Camp Schwab , just a few hundred meters away from the offshore facility . The cited reason for the change is to reduce the engineering challenge associated with building a runway on reefs in deep water : experts estimate that rather than the 15 - plus years required to construct a new airbase at the previous reef location , the new Camp Schwab plan will enable Futenma to be relocated within 6 – 8 years . These plans were also accelerated when a CH - 53D Sea Stallion transport helicopter attached to the 31st Marine Expeditionary Unit lost tail rotor authority and spiraled into the main administrative building of Okinawa International University . Reaction to the new plan for Futenma ' s relocation has been widespread in Okinawa . However , the 2006 mayor of Nago ( which hosts Camp Schwab ) formally agreed to accept the relocation when he signed an agreement with Defense Minister Nukaga on 8 April 2006 . Mayor Shimabukuro was later joined by all five of the major mayors of northern Okinawa . Although some all - Okinawa public opinion polls indicate that many Okinawans have reservations about the latest plan , residents of northern Okinawa have recently elected and re - elected leaders who have publicly accepted it . In fact , all 12 mayors of northern Okinawa have publicly accepted the new relocation plan . In this respect , the Futenma issue exposes a range of conflicting opinions among Okinawans : from those who maintain that military facilities and associated public works infrastructure benefit the island ' s economy ; environmentalists , and those who either object or are critical to the U . S . military presence on ideological grounds or on rooted sentiments . Susumu Inamine ( 稲嶺進 ) the new mayor of Nago city as of 24 January 2010 is against the relocation plan and agrees to move Futenma outside of Okinawa . Besides the local assembly of Nago voting against the relocation plan , the prefectural assembly of Okinawa also formally asked the prime minister to move the base out of the prefecture . On 17 May 2010 ( the anniversary of the reversion of Okinawa to Japan ) people from Okinawa formed a " human chain " around the whole base with estimated 17 , 000 people taking part . This was the fifth time such an action took place . In 2009 , amid controversy throughout Japan over the relocation of the base , Osaka Prefecture governor Toru Hashimoto publicly proposed moving the base ' s functions to Osaka ' s Kansai International Airport ( which is on an artificial island ) , remarking that " the burden [ of bases on Okinawa ] should be spread more evenly throughout Japan . " In 2011 , the chairman and ranking member of the United States Senate Committee on Armed Services called for an alternative plan where Futenma aircraft would move to Kadena Air Base while the current aircraft at Kadena would move to Andersen Air Force Base . A detailed proposal by a former Marine Corps officer would move just one squadron to Kadena and relocate the others to various Navy and Marine Corps airbases in Asia . The replacement of helicopters with the Bell Boeing V - 22 Osprey will allow the Marines to train all along the length of Japan , by using the tiltrotor ' s increased range to bridge the distance to the Japanese main islands . In April 2013 , the United States and Japan released yet another relocation plan for the facility .
