The surrender of Imperial Japan was announced by Japanese Emperor Hirohito on August 15 and formally signed on September 2, 1945, bringing the hostilities of World War II to a close. By the end of July 1945, the Imperial Japanese Navy (IJN) was incapable of conducting major operations and an Allied invasion of Japan was imminent. Together with the British Empire and China, the United States called for the unconditional surrender of the Japanese armed forces in the Potsdam Declaration on July 26, 1945—the alternative being "prompt and utter destruction". While publicly stating their intent to fight on to the bitter end, Japan's leaders were privately making entreaties to the publicly neutral Soviet Union to mediate peace on terms more favorable to the Japanese. While maintaining a sufficient level of diplomatic engagement with the Japanese to give them the impression they might be willing to mediate, the Soviets were covertly preparing to attack Japanese forces in Manchuria and Korea in fulfillment of promises they had secretly made to the United States and the United Kingdom at the Tehran and Yalta Conferences.

The Japanese Instrument of Surrender was the written agreement that formalized the surrender of the Empire of Japan, marking the end of hostilities in World War II. It was signed by representatives from the Empire of Japan, the United States of America, the Republic of China, the United Kingdom of Great Britain and Northern Ireland, the Union of Soviet Socialist Republics, the Commonwealth of Australia, the Dominion of Canada, the Provisional Government of the French Republic, the Kingdom of the Netherlands, and the Dominion of New Zealand. The signing took place on the deck of USS Missouri in Tokyo Bay on September 2, 1945.

The Jewel Voice Broadcast was the radio broadcast of surrender given by Japanese Emperor Emperor Shōwa read out the Imperial Rescript on the Termination of the Greater East Asia War . It announced to the Japanese people that the Japanese Government had accepted the Potsdam Declaration demanding the unconditional surrender of the Japanese military at the end of World War II. Following the Hiroshima bombing on August 6th, Soviet declaration of war and Nagasaki bombing on August 9th, the Emperor's speech was broadcast at noon Japan Standard Time on August 15, 1945, and did reference the atomic bombs as a reason for the surrender.

The Kyūjō incident was an attempted military coup d'état in the Empire of Japan at the end of the Second World War. It happened on the night of 14–15 August 1945, just before the announcement of Japan's surrender to the Allies. The coup was attempted by the Staff Office of the Ministry of War of Japan and many from the Imperial Guard to stop the move to surrender.
USS Missouri (BB-63) is an Iowa-class battleship and was the third ship of the United States Navy to be named after the U.S. state of Missouri. Missouri was the last battleship commissioned by the United States and is best remembered as the site of the surrender of the Empire of Japan, which ended World War II.

V-J Day in Times Square is a photograph by Alfred Eisenstaedt that portrays a U.S. Navy sailor embracing and kissing a total stranger—a dental assistant—on Victory over Japan Day in New York City's Times Square on August 14, 1945. The photograph was published a week later in Life magazine, among many photographs of celebrations around the United States that were presented in a twelve-page section entitled "Victory Celebrations". A two-page spread faces a montage of three similar photographs of celebrators in Washington, D.C., Kansas City, and Miami, opposite the Eisenstaedt photograph that was given a full-page display on the right hand side.

Victory over Japan Day is the day on which Imperial Japan surrendered in World War II, in effect bringing the war to an end. The term has been applied to both of the days on which the initial announcement of Japan's surrender was made – August 15, 1945, in Japan, and because of time zone differences, August 14, 1945 – as well as to September 2, 1945, when the surrender document was signed, officially ending World War II.
