'''[[Operation Downfall]]''' was the proposed [[Allies of World War II|Allied]] plan for the '''invasion of the [[Japanese archipelago|Japanese home islands]]''' near the [[End of World War II in Asia|end of World War II]]. 

The operation had two parts, Operation ''Olympic'', intended to capture the southern third of the southernmost main Japanese island, [[Kyushu|Kyūshū]], and Operation ''Coronet'', the planned invasion of the [[Kantō Plain]], near [[Tokyo]], on the main Japanese island of [[Honshu]]. ''Olympic'' was scheduled for November 1945, to be followed by ''Coronet'' in early 1946. 

If Downfall had taken place, it would have been the largest [[amphibious operation]] in history, surpassing [[Normandy Landings|D-Day]].<ref>{{cite book | chapter = XIII ‘Downfall’ | title = The Plan For The Invasion of Japan | url = http://www.history.army.mil/books/wwii/macarthur%20reports/macarthur%20v1/ch13.htm | access-date = January 23, 2016 | publisher = [[United States Army Center of Military History]] | archive-date = August 17, 2019 | archive-url = https://web.archive.org/web/20190817171601/https://history.army.mil/books/wwii/MacArthur%20Reports/MacArthur%20V1/ch13.htm | url-status = dead }}</ref> The planned operation was canceled when [[Surrender of Japan|Japan surrendered]] following the [[atomic bombings of Hiroshima and Nagasaki]], the [[Soviet–Japanese War|Soviet declaration of war]], and the [[Soviet invasion of Manchuria|invasion of Manchuria]].<ref>{{cite book | last = Giangreco | first = Dennis M. | page = xvi | year = 2009 | title = Hell to Pay: Operation Downfall and the Invasion of Japan, 1945–1947 | publisher = Naval Institute Press | location = Annapolis, MD | isbn = 978-1-59114-316-1 }}</ref>

Should these four corps prove insufficient to accomplish the tasks assigned, elements earmarked for ''Coronet'' would be used to reinforce Sixth Army at the rate of three divisions per month beginning about 30 days after the initial landings.

Thirty days after the initial assault, each army would be reinforced by a corps of 3 divisions. Five days later an airborne division and a United States Army Forces Pacific Reserve Corps of 3 divisions would be made available. Strategic reserve for the entire operation would consist of a corps of 3 divisions located in the Philippines and divisions from the United States to permit reinforcement at the rate of 4 per month.<ref name="Downfall"/>

All Japanese formations on [[Honshu]] were badly understrength and lacking in equipment. The American First Army's landings would likely have been opposed by the Japanese 52nd Army and the Eighth Army's landings by the Japanese 53rd Army.
