In preparation for the invasion, an air campaign against Japanese airfields and transportation arteries had commenced before the Japanese surrender. Japanese intelligence predicted fairly closely where the invasion would take place: southern Kysh at Miyazaki, Ariake Bay and/or the Satsuma Peninsula. . [41] However, the IJN lacked enough fuel for further sorties by its capital ships, planning instead to use their anti-aircraft firepower to defend naval installations while docked in port. The operation for the occupation of Japan following the landing may be a very long, costly and arduous struggle on our part. Ultimately, the Navy partially conceded, and MacArthur was to be given total command of all forces if circumstances made it necessary.

The last great island battle of Okinawa began with an onslaught of shells, rockets and bombs from 1300 ships (the British Pacific Fleet also took part). Operation August Storm, the massive 1945 Soviet invasion of Manchuria, was Japan's death blow, and brought an end to World War II. The estimated casualty figures later became a crucial point in postwar debate over the atomic bombings of Hiroshima and Nagasaki. Emperor Hirohito, in a meeting with his Imperial Council, stated that he wished to surrender as long as the role of the emperor was not compromised. Nimitz planned a pre-invasion feint, sending a fleet to the invasion beaches a couple of weeks before the real invasion, to lure out the Japanese on their one-way flights, who would then find ships bristling with anti-aircraft guns instead of the valuable, vulnerable transports. This area would then be used as a further staging point to attack Honshu in Operation Coronet. The Allies decided to launch a two-stage invasion. Kysh was to be invaded by the Sixth United States Army at three points: Miyazaki, Ariake, and Kushikino. For the failed Mongol invasion attempts, see, "Soviet invasion of Japan" redirects here.

In a conference with President Truman on June 18, Marshall, taking the Battle of Luzon as the best model for Olympic, thought the Americans would suffer 31,000 casualties in the first 30 days and ultimately 20% of Japanese casualties, which he estimated would include the entire Japanese force.
