What was the Allied plan to invade Japan?
Operation Downfall was the proposed Allied plan for the invasion of the Japanese home islands near the end of World War II.
What two places did the Japanese plan to invade?
In January 1945 Japan’s high command anticipated exactly what the U.S. would do — and began to plan for it. Japanese strategists predicted correctly that Americans would assault the islands of Iwo Jima and then Okinawa, where the Japanese hoped fierce resistance would force a negotiated peace.
What were the phases of Operation Downfall?
Operation Downfall itself was divided into two parts – Operation Olympic and Operation Coronet. By mid-1945, it was apparent that the collapse of Japan was near and the Allies had to plan for the invasion of the Japanese mainland – something that they knew would be very costly in terms of lives lost.
Who planned Operation Downfall?
Downfall was the brainchild of Admiral Chester Nimitz and generals Douglas MacArthur and George Marshall. It was comprised of TWO mammoth amphibious operations. The first phase, dubbed Operation Olympic was planned as a November, 1945 assault on the southernmost Japanese home island of Kyushu.
Which military strategy did the Allies use to defeat Japan in the Pacific War?
Leapfrogging
Leapfrogging was a military strategy employed by the Allies in the Pacific War against the Axis powers (most notably Japan) during World War II. It entailed bypassing and isolating heavily fortified Japanese positions while preparing to take over strategically important islands.
What was Operation Olympia?
Operation Olympic was the code-name for a planned landing in Kyushu – the furthest main island in the south. Once an amphibious landing had occurred, the Americans planned to move inland but only for about one-third of the island. Airbases would then be set-up to support Operation Coronet.

How many Japanese would have died in Operation Downfall?
In late July 1945, the War Department provided an estimate that the entire Downfall operations would cause between 1.7 to 4 million U.S. casualties, including 400-800,000 U.S. dead, and 5 to 10 million Japanese dead.

How did the Allies defeat Japan?
Aboard the USS Missouri in Tokyo Bay, Japan formally surrenders to the Allies, bringing an end to World War II. The Japanese navy and air force were destroyed. The Allied naval blockade of Japan and intensive bombing of Japanese cities had left the country and its economy devastated.
What strategy did the United States use to defeat the Japanese?
The American strategy to defeat the Japanese was to island hop around Japan, not to attack their country directly but to take over all the islands around it and surround them and hopefully starve them to surrender. It was led General MacArthur and also Admiral Chester Nimitz.
What were the two main operations of the invasion of Japan?
The invasion plan was assigned the cover name “Downfall” and consisted of two main operations: “Olympic,” the preliminary assault on the southern island of Kyushu, which was slated for 1 December 1945, and “Coronet,” the subsequent landing on Honshu, which was scheduled for 1 March 1946.
How did the US get Japan to surrender in WW2?
The United States Navy urged the use of a blockade and airpower to bring about Japan’s capitulation. They proposed operations to capture airbases in nearby Shanghai, China, and Korea, which would give the United States Army Air Forces a series of forward airbases from which to bombard Japan into submission.
How did Japan’s geography affect Operation Ketsugō?
Japan’s geography made this invasion plan quite obvious to the Japanese as well; they were able to accurately predict the Allied invasion plans and thus adjust their defensive plan, Operation Ketsugō, accordingly. The Japanese planned an all-out defense of Kyūshū, with little left in reserve for any subsequent defense operations.
How many Japanese died in Operation Downfall?
Operation Downfall — The Campaign to Conquer Japan Would Have Dwarfed the D-Day Landings. The plan to invade the Japanese home islands in 1945 and 1946 would have been the deadliest campaign in military history costing nearly 1 million Allied dead and up to 10 million Japanese.
