The ceremony aboard USS Missouri lasted 23 minutes when Japan surrendered in 1945. It began shortly after 9 a.m. and concluded at 9:25 a.m. Japan Standard Time.
Despite its enormous historical importance, the event was deliberately brief and tightly organized. Japanese representatives signed first, followed by MacArthur and the Allied representatives. Each participant had a designated place and a defined role, reducing the risk of confusion during a ceremony watched by military personnel and journalists.
The short duration should not be confused with the length of the political crisis that preceded it. Japan’s government debated surrender after the atomic bombings, the Soviet declaration of war, and the emperor’s intervention. The August 15 broadcast announced acceptance of the Allied terms, but the September 2 ceremony provided the formal international act. The 23-minute figure refers specifically to the signing proceedings aboard Missouri.
