Marine Corps Air Station Futenma is a United States military installation located in Ginowan City, Okinawa Prefecture, Japan. It serves as a key operational base for U.S. Marine Corps aviation assets in the Pacific region, hosting helicopters, tilt-rotor aircraft, and fixed-wing aircraft. The base has been a source of significant political controversy due to its location in the densely populated urban area of Ginowan. Discussions about relocating or closing the facility have been ongoing for decades, involving negotiations between the U.S. and Japanese governments. Futenma is not open to commercial aviation and handles no civilian passenger traffic. It operates exclusively under U.S. military authority as part of the broader network of U.S. Forces Japan (USFJ) installations on Okinawa.
