Think about this... we lost 2000 on Tarawa, 5000 on Iwo and 10,000 on Okinawa. You have a comic book view of history.
My point was that, although there were many battles yet to be fought after Midway, from that point on the Japanese were essentially fighting to either hold on to what they had or retreating. The reason that we lost so many men in ground battles was that the average Japanese (citizen and soldier) had been tought that we would torture them, if they were captured. The Japanese soldiers did not see surrender as an option. In Okinawa, thousands of women jumped off of the cliffs with their children, for fear of being captured alive.
We lost a lot of men to acts of desperation, on the part of the Japanese, both on the battle field and on the seas. After all, it wasn't the towel heads who invented the idea of flying a plane into a stationary structure on a suicide mission.
When an enemy is losing and doesn't see surrender as an option, the desperation that follows can usually cause a lot of damage and death on both sides. But, unless the other side makes a big mistake, those acts of desperation generally leave the enemy in even worse shape. Even so, they can still cause a lot of damage in those acts of desperation.
Documents from that time show that many in the Japanese government and military we not entirely convinced, going into the war, that they could win. But, they did believe that they could put up a good fight.
There is a big difference between winning and putting up a good fight. After Midway, the Japaneese put up a good fight, but they were not winning.
