After the war, Okinawa was put under the U.S. military. The people expected freedom, but priority was given to U.S. military policy. Therefore, the movement for a return to Japan was strengthened, and it was carried out in 1972.

Many US military bases are still left, and crimes by a few US soldiers continue to be a social problem.
