Who signed Japan’s surrender for Imperial General Headquarters aboard USS Missouri?

Yoshijiro Umezu signed Japan’s surrender for Imperial General Headquarters aboard USS Missouri.

Umezu was the Chief of the Army General Staff and the senior uniformed Japanese representative at the ceremony. After Foreign Minister Mamoru Shigemitsu signed for the Emperor and the Japanese government, Umezu signed for Japanese Imperial General Headquarters at approximately 9:06 a.m. local time.

The arrangement reflected Japan’s wartime power structure. The civilian government and the military headquarters were treated as separate parties for the purpose of the surrender document. Umezu’s signature bound the Japanese armed forces to the terms requiring them to cease resistance and surrender to Allied commanders.

Umezu had opposed surrender before Emperor Hirohito made the final decision, but he ultimately followed the imperial command. He was later tried before the International Military Tribunal for the Far East and received a life sentence, dying in prison in 1949.
