Eleven Japanese delegates were listed for the formal surrender ceremony on September 2, 1945.
The Japanese delegation included Foreign Minister Mamoru Shigemitsu and General Yoshijirō Umezu, Chief of the Army General Staff. Shigemitsu signed on behalf of the emperor and Japanese government, while Umezu signed on behalf of Imperial General Headquarters. The remaining delegates represented the army, navy, and foreign ministry.
The delegation traveled from Tokyo to Yokohama and then boarded a smaller vessel for USS Missouri, which was anchored in Tokyo Bay. The ceremony began shortly after 9:00 a.m. Japan Standard Time and lasted about twenty-three minutes.
Only Shigemitsu and Umezu signed the Instrument of Surrender for Japan. The other listed delegates served as official representatives and witnesses. This is why accounts may mention eleven Japanese delegates but only two Japanese signatures on the document.
