The Japanese Instrument of Surrender ceremony was officially concluded at 9:25 a.m. on September 2, 1945.
The signing took place aboard USS Missouri in Tokyo Bay. Japanese representatives began signing shortly after 9:00 a.m., with Foreign Minister Mamoru Shigemitsu signing at about 9:04 a.m. and General Yoshijirō Umezu signing at about 9:06 a.m.
Allied representatives then signed the instrument. General Douglas MacArthur signed for the Allied powers, while Admiral Chester Nimitz represented the United States. Representatives from China, the United Kingdom, the Soviet Union, Australia, Canada, France, the Netherlands, and New Zealand also signed.
The distinction between the conclusion time and the signing times matters. The war did not become formally over merely when the first Japanese signature was placed on the document. After all required representatives had signed and MacArthur delivered closing remarks, the ceremony ended at 9:25 a.m. Tokyo time.
