<P> Operation Downfall was the proposed Allied plan for the invasion of Japan near the end of World War II . The planned operation was abandoned when Japan surrendered following the atomic bombings of Hiroshima and Nagasaki , the Soviet declaration of war and the Soviet invasion of Manchuria . The operation had two parts : Operations Olympic and Coronet . Set to begin in November 1945 , Operation Olympic was intended to capture the southern third of the southernmost main Japanese island , Kyūshū , with the recently captured island of Okinawa to be used as a staging area . Later , in the spring of 1946 , Operation Coronet was the planned invasion of the Kantō Plain , near Tokyo , on the Japanese island of Honshu . Airbases on Kyūshū captured in Operation Olympic would allow land - based air support for Operation Coronet . If Downfall had taken place , it would have been the largest amphibious operation in history . </P>
