Who was Japan's foreign minister and first signatory of the Japanese Instrument of Surrender?

Mamoru Shigemitsu was Japan's foreign minister and first signatory of the Japanese Instrument of Surrender.

Shigemitsu signed at 9:04 a.m. on September 2, 1945, aboard the USS Missouri. He signed on behalf of Emperor Hirohito and the Japanese government. His prosthetic leg and formal morning coat made him a recognizable figure in photographs of the ceremony; he had lost his right leg in a 1932 assassination attempt in Shanghai.

General Yoshijirō Umezu signed immediately afterward for the Japanese Imperial General Headquarters. The two men represented different parts of the Japanese state: Shigemitsu represented the government, while Umezu represented the military headquarters.

Shigemitsu had served as foreign minister during the final stage of the war and later returned to that office in postwar Japan. He was convicted at the Tokyo Trial but was released in 1950 and again became foreign minister before dying in 1957.
