Operation Downfall consisted of two parts Operation Olympic and Operation Coronet. Set to begin in October 1945, Operation Olympic was intended to capture the southern third of the southernmost main Japanese island of 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 Honshū. Airbases on Kyūshū captured in Operation Olympic would allow land-based air support for Operation Coronet.
Japan's geography made this invasion plan obvious to the Japanese as well; they were able to accurately deduce the Allied invasion plans and adjust their defensive plans accordingly. The Japanese planned an all-out defense of Kyūshū, with little left in reserve for any subsequent defense operations. Casualty predictions varied widely but were extremely high for both sides: depending on the degree to which Japanese civilians resisted the invasion, estimates ran into the millions for Allied casualties, and tens of millions for Japanese casualties...
Thank you for your scholarship on the subject. I wonder why that PhD candidate from George Washington Univ, who was the presentor at the Enola Gaye exhibit at the Smithsonian, was not aware of the knowledge you and I have on the subject. Almost seems like a pre-determined agenda.
