The Allied occupation of Japan at the end of World War II was led by the United States, whose then-President Harry S. Truman appointed General Douglas MacArthur as the Supreme Commander for the Allied Powers, with support from the British Commonwealth. Unlike in the occupation of Germany, the Soviet Union was allowed little to no influence over Japan. This foreign presence marks the only time in Japan's history that it has been occupied by a foreign power. At MacArthur's insistence, Emperor Hirohito remained on the imperial throne. The wartime cabinet was replaced with a cabinet acceptable to the Allies and committed to implementing the terms of the Potsdam Declaration, which among other things called for the country to become a parliamentary democracy. Under MacArthur's guidance, the Japanese government introduced sweeping social reforms and implemented economic reforms that recalled American "New Deal" priorities of the 1930s under President Roosevelt. The Japanese constitution was comprehensively overhauled and the Emperor's theoretically-vast powers, which for many centuries had been constrained by conventions that had evolved over time, became strictly limited by law. The occupation, codenamed Operation Blacklist, was ended by the San Francisco Peace Treaty, signed on September 8, 1951, and effective from April 28, 1952, after which Japan's sovereignty – with the exception, until 1972, of the Ryukyu Islands – was fully restored.

The American public demanded a rapid demobilization and soldiers protested the slowness of the process. Military personnel were returned to the United States in Operation Magic Carpet. By June 30, 1947, the number of active duty soldiers, sailors, Marines, and airmen in the armed forces had been reduced to 1,566,000.

The Shibuya incident was a violent confrontation which occurred in June 1946 between rival gangs near the Shibuya Station in Tokyo, Japan.

In the chaos of the post-war recovery large and very lucrative black markets opened throughout Japan. Various gangs fought for control over them. There were also many non-Japanese "third nationals" in post-war Japan. These "third nationals" or "third-country people" were former subjects of the Empire of Japan whose citizenship then transferred to other countries like China and Korea.

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.
