Surrender of Japan, Tokyo Bay, 2 September 1945
Spectators and photographers crowd USS
Missouri's superstructure to witness the formal ceremonies marking Japan's surrender, 2 September 1945.
The framed flag in lower right is that hoisted by Commodore Matthew C. Perry on 14 July 1853, in Yedo (Tokyo) Bay, on his first expedition to negotiate the opening of Japan. It had been brought from its permanent home in Memorial Hall at the U.S. Naval Academy for use during the surrender ceremonies.
