Why did the Japanese lose the war (did they?)what made America so great? they were willing to die Japs had all the advantage the guns, ppl.?

The Japanese had hoped to be able to secure the pacific theater before the US could effectively mount a counter attack. Ships need refueling and the tactical range of a fleet is limited by that factor.

They lost the war for several reasons, the primary one was the failure of the attack on Pearl. The port was damaged but the sub pens were mostly intact, the aircraft carriers were not in port and the task force failed to launch the second wave of strikes.

The second reason is that Germany failed to capture the Suez Canal. If that had been done Australia and India would have been cut off from England.

The third reason was that naval intelligence had broken the military code allowing the US fleet to know where to look for the Japanese fleet.

Another reason was bad luck! The Battle of Midway would have gone much differently if the first Japanese air plane to spot the US fleet would have had a transmitter that worked. This was not the only seemingly coincidence that resulted in the Japanese loosing battles.

The last reason is inferior naval architecture. War records suggest that the Japanese fleet did not have as good of water tight integrity plan as US naval ships. It took fewer hits to sink one of them.

That last reason carries over to aircraft and tanks! The equipment was inferior to the equipment the allies were using. Loosing an aircraft is bad, but loosing both the pilot and the aircraft is worse. There just were not that many Japanese pilots that got shot down that lived to fly again. While the allies did recover many who were better pilots after the experience then before it happened. The same is true for the ground forces, the Japanese once they started loosing ground did not have as many seasoned troops to use in combat.

All that said, one historian suggested the primary reason for the Japanese loosing the war was that the leadership instead of retreating committed suicide to avoid the consequences. That the failure of the Japanese leadership to understand why MacArthur was a hero even when he fled the battle field is but one example.

One of the contributing factors to Japan starting the war was the the US embagoed the steel scrap Japan needed to manufacture weapons. The USA had the biggest steel industry in the world, the Japanese relied on scrap, and decided to start a fight with the big guys. Total lunacy, based on the crazy idea of racial superiority. "Those white devils can't possibly beat the empire blessed by heaven."

If you mean the Pacific War of 1941-45, Japan's defeat is the most comprehensive defeat suffered by any nation in at least the last thousand years.

Their starting a war with the US was beyond being merely stupid, as, unlike Nazi Germany, they had NO possibility of not losing the resulting war. Even if their attack had sunk all three US Pacific Fleet carriers at Midway, all that would have meant is that when the massive flow off arms and men started to come in 1943, the US would have had to push Japan's forces back from a slightly bigger perimeter.

Note that in the Battle of the Philippine Sea, where the US Fifth Fleet ended the power of the Japanese Navy's carrier force, the US had 15 fast carriers in their fleet, all but one not being in service prior to 31 Dec 1942.

The decision making process in Imperial Japan was, well, insane. On that basis, they started a war they could not fail to lose, and the same process delayed them finally grasping that they had lost.

Among the basic reasons why they lost, the US had resources and industrial capacity that were both many, many times greater than Japan had or could hope to have. There was no way for them to get around that basic fact.

The main thing was production and supply abilities. The United States simply outproduced Japan.
