Location of Katsuyama near Nago, Okinawa

The Cave of the Negroes incident was a killing of three African American Marines by Okinawans from the Katsuyama village near Nago, Okinawa after the Battle of Okinawa in 1945, shortly before the end of the war in the Pacific. Their bodies were hidden in the nearby cave and the incident was kept a secret until 1997. Since the killings, the cave has been known as Kurombo Gama, which translated means Cave of the Negroes in English.


Villagers of the Katsuyama village in Okinawa claim that they were victims of sexual attacks. According to villagers, three men, US Marines, came to the village every weekend, forced the men to hand over the women, and then sexually assaulted them.[1]

The attackEdit

Decades later, villagers revealed that the marines were so confident that the Japanese were powerless that they often came to the village without weapons.[2] Taking advantage of this, the villagers ambushed the Americans with the help of two armed Japanese soldiers who were hiding in the nearby jungle.[2] Shinsei Higa, a retired teacher, who was sixteen at the time, remembers that "I didn't see the actual killing because I was hiding in the mountains above, but I heard five or six gunshots and then a lot of footsteps and commotion. By late afternoon, we came down from the mountains and then everyone knew what had happened."[1]

To cover up the American deaths, the bodies were dumped in a local cave that had a 50 foot (15 m) drop off close to its entrance. Ever since the bodies were dumped in the cave, it has been known as Kurombo Gama, which translated means Cave of the Negroes.[1]

When the men did not return to their Marine Corps posts, they were listed as possible deserters in the summer of 1945. After a year with still no evidence of what happened to them, they were declared missing in action.[1]


Kijun Kishimoto was almost thirty during the incident and grew up in Katsuyama. He was away from the village when the men were killed. In an interview, he said, "People were very afraid that if the Americans found out what happened there would be retaliation, so they decided to keep it a secret to protect those involved."[1]

Finally, a guilty conscience led Kishimoto to contact Setsuko Inafuku, a tour guide for Kadena United States Air Base in Okinawa who was involved in the search for deceased servicemen from the war.[1] The two searched for the cave in June 1997 but could not find it until a storm blew down the tree blocking the entrance that summer.[1] The local Japanese police were informed but they kept it secret for a few months to protect the people who discovered the location of the bodies.

When they finally told Marine officials, the USMC located the bodies at the bottom of the mine shaft. Using dental records all men were identified as the 19 year-old Marines who went missing in 1945. Their names were Pfc. James D. Robinson of Savannah, Ga., Pfc. John M. Smith of Cincinnati, and Pvt. Isaac Stokes of Chicago.[1]


No plans were made to criminally investigate the incident by either the United States military or the Okinawa police.[1]

After the Battle of Okinawa, the island chain was occupied under the United States Civil Administration of the Ryukyu Islands until 1972. At that time, the U.S. government returned the islands to Japanese administration. Under the Treaty of Mutual Cooperation and Security, the United States Forces Japan (USFJ) have maintained a large military presence: 27,000 personnel, including 15,000 Marines, contingents from the Navy, Army, and Air Force, and their 22,000 family members are stationed in Okinawa.[3]
