Who was the second Japanese representative to sign Japan's 1945 surrender document?

Yoshijirō Umezu was the second Japanese representative to sign Japan's 1945 surrender document.

Umezu was Chief of the Army General Staff and signed on behalf of Japan's Imperial General Headquarters. Mamoru Shigemitsu had signed first for the Emperor and the Japanese government. Umezu followed at approximately 9:06 a.m. Japan Standard Time.

The distinction between the two Japanese signatures matters because Japan's government and military command were represented separately. The surrender document required both institutions to accept the Allied terms and stop resistance. Umezu wore his army uniform during the ceremony and signed at the table on USS Missouri's deck.

Umezu had opposed surrender within Japan's wartime leadership, but he ultimately carried out the Emperor's order to sign. He was later tried by the International Military Tribunal for the Far East and convicted of war crimes. He died in prison in 1949, before completing his sentence.
