The 1945 Katsuyama killing incident was the murder of three African-American United States Marines in Katsuyama near Nago, Okinawa after the Battle of Okinawa on July 10, 1945 to August 13, 1946. Residents of Katsuyama had reportedly killed the three Marines for their repeated rape of village women during occupation of Okinawa and hid their bodies in a nearby cave out of fear for retaliation. The Katsuyama incident was kept secret until August 16, 1997 when the bodies and identities of the Marines were discovered.
