Why did japan suffer defeat in word war?

Answer 1

The atomic bombs- "little boy" and "fat man" they were called- they dropped on two large cities in Japan and they caused the death of many lives Japan surrendered soon after the bombs.

Japan was already beaten by the time the A bombs were used. They insisted in fighting on even though B29s were now bombing Japanese cities with conventional bombs at will. The US chose to use A bombs to end the war quickly without armed invasion, which they calculated would cause greater loss of life than A bombs. Nagasaki and Hiroshima, two medium sized cities, were chosen to demonstrate the enormous power of this weapon, along with the unspoken threat 'give up now,or Tokyo and Kobe are next'.

When Japan attacked Pearl Harbor they truly believed that the US, being made up of a mongrel mix of races [not my words] would not be able to re-organize and regather after such a successful and devastating attack in the manner of a super and pure race like them. Mistake No1. every fighting man knows this 'Never under-estimate your enemy'. Mistake No2. They attacked the largest industrial power the world had ever seen but had not realized how quickly the US could put that power into war production and turn it into the largest military power the world had ever seen. A Juggernaut the Japanese could never defeat.

There are additional reasons the Japanese lost the war. They suffered the deaths of millions of soldiers. They were overextended across the Pacific. Japan (including Korea and Taiwan at that time) had a very strong military but very little access to oil and limited access to coal and iron. By 1944, Japan was losing more shipping than their entire national output of steel. Almost no oil made it to Japan in 1944 and no significant oil reached the islands in 1945. All of the preceding thoughts are true, but it is important to realize that the Japanese ability to wage war was doomed to fail. Despite all of that, everything said here, Japan could still put on a horrific defense of a small area at a great cost to America. The two final island campaigns (Iwo Jima and Okinawa) cost America 20,000 dead. Predictions were floated in the White House and Pentagon that the invasion of the four home islands -- each many times better defended than Iwo Jima and Okinawa -- might take 500,000 American lives while destroying nearly all of Japan's men. By comparison, the final decision to use the atomic bombs seems almost merciful.
