Eight Allied countries besides the United States signed Japan’s surrender document.
The other signatory countries were China, the United Kingdom, the Soviet Union, Australia, Canada, France, the Netherlands, and New Zealand. Together with the United States, they made nine Allied national representatives who signed after General Douglas MacArthur accepted the surrender.
The ceremony reflected the broad coalition that had fought Japan across the Asia-Pacific region and beyond. Each country’s representative signed on behalf of a government or military authority. Fleet Admiral Chester Nimitz represented the United States, while General Hsu Yung-chang represented China and Admiral Sir Bruce Fraser represented the United Kingdom.
The count can be confusing because MacArthur signed first as Supreme Commander for the Allied Powers, not as one of the individual national representatives. The Japanese delegation also included two principal signatories: Mamoru Shigemitsu for the government and Yoshijirō Umezu for Imperial General Headquarters.
