Eight Allied countries besides the United States were represented by signatories at Japan’s 1945 surrender.
The countries were China, the United Kingdom, the Soviet Union, Australia, Canada, France, the Netherlands, and New Zealand. Together with the United States, they formed the nine Allied national representatives who signed after General Douglas MacArthur accepted the surrender on behalf of the Allied powers.
Fleet Admiral Chester Nimitz signed for the United States. The other national representatives signed in sequence after him, with General Hsu Yung-chang representing China and Admiral Sir Bruce Fraser representing the United Kingdom among the best-known delegates.
The number can be confusing because MacArthur also signed, and Japanese officials signed separately. Counting every individual at the ceremony therefore produces a different total from counting Allied countries represented by national signatories.
