Where did Japan sign the Instrument of Surrender in 1945?

Japan signed the Instrument of Surrender in Tokyo Bay.

The ceremony occurred on the deck of USS Missouri, which was anchored in the bay near Tokyo on September 2, 1945. The location allowed the Allies to conduct a highly visible naval ceremony close to Japan's capital while avoiding the logistical difficulties of holding the event in a heavily damaged city.

Delegates from Japan arrived by boat and boarded Missouri before the ceremony. Foreign Minister Mamoru Shigemitsu and General Yoshijiro Umezu signed the document for Japan. Allied representatives, led by General Douglas MacArthur, followed with their signatures. Ships from the American and other Allied fleets were gathered nearby.

Tokyo Bay is not the same place as Pearl Harbor, where the United States suffered the December 7, 1941 attack that brought the United States directly into the Pacific War. Nor was the document signed in Hiroshima or Nagasaki, the two Japanese cities struck by atomic bombs in August 1945. Those events occurred before the formal surrender ceremony.
