Eleven Japanese delegates were present for the signing of the Instrument of Surrender in 1945.
Only two of the eleven Japanese delegates actually signed the document: Foreign Minister Mamoru Shigemitsu and General Yoshijiro Umezu. The other nine delegates attended as representatives of Japan's army, navy, and foreign ministry but did not add signatures to the instrument.
The full delegation left Tokyo early on September 2 and traveled to Yokohama. From there, the delegates boarded a vessel that took them to USS Missouri, which was anchored in Tokyo Bay. For security reasons, the Allies released only the names of the two signatories to the press before the ceremony.
The delegation's composition reflected the divided structure of wartime Japanese authority. Shigemitsu represented the civilian government, while Umezu represented Imperial General Headquarters. The presence of military and diplomatic officials made the surrender applicable to both the government and Japan's armed forces.
