In 1995, the abduction and rape of a 12-year-old Okinawan schoolgirl by two U.S. Marines and one U.S. sailor led to demands for the removal of all U.S. military bases in Japan. Other controversial incidents include helicopter crashes, the Girard incident, the Michael Brown Okinawa assault incident, the death of the Kinjo family and the death of Yuki Uema. In February 2008, a 38-year-old U.S. Marine based on Okinawa was arrested in connection with the reported rape of a 14-year-old Okinawan girl. This triggered waves of protest against American military presence on Okinawa and led to tight restrictions on off-base activities. Although the accuser withdrew her charges, the U.S. military court-martialed the suspect and sentenced him to four years in prison under the stricter rules of the military justice system.
