The surrender of the Empire of Japan on September 2, 1945, brought the hostilities of 
World War II to a close. By the end of July 1945, the 
Imperial Japanese Navy was incapable of conducting operations and an 
Allied invasion of Japan was imminent. While publicly stating their intent to fight on to the bitter end, the 
Empire of Japan's leaders, (the 
Supreme Council for the Direction of the War, also known as the "Big Six"), were privately making entreaties to the neutral Soviet Union
 to mediate peace on terms favorable to the Japanese. The Soviets, 
meanwhile, were preparing to attack the Japanese, in fulfillment of 
their promises to the United States and the United Kingdom made at the 
Tehran and 
Yalta Conferences.

 On August 6, 1945, the United States dropped an 
atomic bomb on the city of Hiroshima. Late in the evening of August 8, 1945, in accordance with the Yalta agreements, but in violation of the 
Soviet–Japanese Neutrality Pact, the Soviet Union declared war on the Empire of Japan, and soon after midnight on August 9, 1945, the 
Soviet Union invaded the Imperial Japanese puppet state of Manchukuo. Later that day, the United States dropped another atomic bomb, this time on the city of 
Nagasaki. The combined shock of these events caused 
Emperor Hirohito to intervene and order the Big Six to accept the terms for ending the war that the Allies had set down in the 
Potsdam Declaration. After several more days of behind-the-scenes negotiations and 
a failed coup d'état, Emperor Hirohito gave a recorded radio address to the Empire on August 15. In the radio address, called the 
Gyokuon-hōsō ("Jewel Voice Broadcast"), he announced the surrender of the Empire of Japan to the Allies.

On August 28, the 
occupation of Japan by the 
Supreme Commander for the Allied Powers began. The surrender ceremony was held on September 2, aboard the United States Navy battleship 
USS Missouri (BB-63), at which officials from the Japanese government signed the 
Japanese Instrument of Surrender, thereby ending the hostilities in World War II. Allied civilians and military personnel alike celebrated 
V-J Day,
 the end of the war; however, some isolated soldiers and personnel from 
Imperial Japan's far-flung forces throughout Asia and the Pacific 
islands 
refused to surrender for months and years afterwards, some even as far as into the 1970s. Since the surrender of the 
Empire of Japan, historians 
have continually debated the ethics of using the atomic bombs on Hiroshima and Nagasaki.
The state of war between Japan and the Allies formally ended when the 
Treaty of San Francisco came into force on April 28, 1952. Four more years passed before Japan and the Soviet Union signed the 
Soviet–Japanese Joint Declaration of 1956, which formally brought an end to their state of war.
