In which body of water was Japan's Instrument of Surrender signed?

Japan’s Instrument of Surrender was signed in Tokyo Bay.

The ceremony occurred on the deck of USS Missouri on 2 September 1945. Tokyo Bay provided a secure anchorage near Japan’s capital while allowing a large Allied fleet to remain in the area. The surrounding ships and aircraft demonstrated that Japan had lost control of the war at sea and in the air.

The location also carried historical symbolism. Missouri anchored near the area where Commodore Matthew Perry’s American squadron had anchored in 1853. Perry’s expedition led to the Convention of Kanagawa, which ended Japan’s long policy of restricting foreign contact and opened ports to U.S. commerce.

Tokyo Bay should not be confused with the Imperial Palace, where Hirohito recorded his surrender address, or with Potsdam, where the Allied declaration setting out surrender terms was issued. The bay was the site of the later, formal signing ceremony. Afterward, occupation forces began entering Japan, while separate surrender ceremonies took place in other parts of the former Japanese empire.
