After the
Battle of Wake Island on December 23, 1941, Sakaibara was appointed the garrison commander of the Japanese occupation force. Fearing an imminent attempt by American forces to retake the island, Sakaibara put 98 American civilians they had captured to work building a series of bunkers and fortifications in preparation for a suspected
amphibious invasion.
On October 5, 1943, aircraft from
USS ''Yorktown'' bombed Wake Island. Two days later, Sakaibara ordered the beheading of an American civilian worker who was caught stealing. Fearing an invasion, Sakaibara ordered the rest of them to be killed. They were taken to the northern end of the island, blindfolded and machine-gunned. One prisoner (whose name has never been discovered) escaped, carved a message into a rock about the incident but was then recaptured and personally
beheaded by Sakaibara.
However, despite the massive assembly, the attack never came. Instead the

a year later, on October 15, 1944. The Japanese garrison on Wake Island formally surrendered to the United States on September 4, 1945.

After the war, Sakaibara, his subordinate, Lieutenant Commander Shoichi Tachibana, and Toraji Ito, was taken into custody by the
American occupation authorities. They initially claimed that the victims were killed in a bombing raid by U.S. forces, but later confessed to the massacre.
Sakaibara, Tachibana, and Ito were extradited to
Kwajalein Island, where they were tried for war crimes by a U.S. military commission. Ito killed himself in custody. Sakaibara and Tachibana were both found guilty and sentenced to death in December 1945. Tachibana's sentence was commuted to life in prison, and he was sent to

Just before he was sentenced, Sakaibara read out a final statement to the commission. He admitted that what he did was wrong and said he wished that he had never heard of Wake Island. However, Sakaibara also claimed that the United States had no moral authority to try him or others after using nuclear weapons on Japan. With that statement, many people in Sakaibara's hometown saw him as a victim of victor's justice.
