Who signed Japan's surrender on behalf of the Allied nations during the September 2, 1945 ceremony?

Douglas MacArthur signed Japan's surrender on behalf of the Allied nations during the September 2, 1945 ceremony.

MacArthur was the Supreme Commander for the Allied Powers in the Southwest Pacific Area and had been appointed to oversee Japan's surrender and occupation. He signed the instrument first for the Allies, using five pens that he later distributed as souvenirs.

Fleet Admiral Chester W. Nimitz then signed as the United States representative. Representatives of other Allied governments followed, including China, the United Kingdom, the Soviet Union, Australia, Canada, France, the Netherlands, and New Zealand.

MacArthur also delivered brief opening and closing remarks at the ceremony. His role should not be confused with Nimitz's: MacArthur represented the Allied command, while Nimitz signed specifically for the United States. The Japanese document was signed first by Foreign Minister Mamoru Shigemitsu and then General Yoshijiro Umezu.
