Answer:
Explanation:
Depends on what part of the war you are talking about.
In the beginning, before Pearl Harbor, the Japanese were well equipped and had superb military leaders. They had all they needed to take whatever they needed.
After Pearl Harbor and before Midway, they still had advantages but the very thing that Yamamoto didn't want happened. America, the sleeping Giant, had now entered the war. The battles seesawed, but America did not have battle hardened soldiers. That was true of both fronts, but Europe was different, but it is not part of your question.
After Midway, the Japanese began to lose their advantage and rather quickly. They still had men who fought tenaciously, but eventually the allies began to make them pay. It was hard to get supplies to the ground troops for one thing.
It is said that after Doolittle's raid on Tokyo, Japan never won another major battle.
