Eight other Allied nations signed Japan’s surrender document after the United States representative.
At the September 2, 1945, ceremony, General Douglas MacArthur signed for the Allied powers and Fleet Admiral Chester Nimitz signed as the United States representative. Representatives of eight additional Allied nations then signed the Instrument of Surrender.
Those nations were China, the United Kingdom, the Soviet Union, Australia, Canada, France, the Netherlands, and New Zealand. Their representatives reflected the broad coalition that had fought Japan across Asia and the Pacific.
The count can be confusing because MacArthur’s signature represented the Allied powers in his role as Supreme Commander, while Nimitz represented the United States specifically. The document therefore contains more than ten signatures but eight national representatives after the American signing. Japan’s representatives signed first, with Mamoru Shigemitsu representing the government and Yoshijirō Umezu representing the armed forces.
