Nine Allied nations had their own representatives sign Japan’s Instrument of Surrender in 1945.
The nine were the United States, China, the United Kingdom, the Soviet Union, Australia, Canada, France, the Netherlands, and New Zealand. General Douglas MacArthur signed first as Supreme Commander for the Allied Powers, and Fleet Admiral Chester Nimitz then signed for the United States.
The national representatives signed in a carefully arranged order. General Hsu Yung-chang signed for China, Admiral Sir Bruce Fraser for Britain, Lieutenant General Kuzma Derevyanko for the Soviet Union, and representatives of the other five Allied nations followed.
This total counts the national Allied signatories, not the two Japanese signatories or the wider group of military and naval personnel present at the ceremony. The ceremony therefore represented a broad coalition, even though the United States organized and hosted it aboard USS Missouri.
