People in Okinawa more or less feel Japan has continued to betray them, according to local officials.
"There is no safe place around here," said Kiyoshi Nakamura, head of the Ginowan district of the Okinawa city of Ginowan, looking up at a U.S. Marine Corps MV-22 Osprey tilt-rotor airplane flying over a residential area.
The United States deployed Osprey aircraft to Marine Corps Air Station Futenma, in densely populated Ginowan, in 2012. Local people no longer look up when the aircraft fly overhead because the flights have become part of everyday life.
