If you're interested in a Japanse ace, then look for anything about Sakai Saburo. He was the 3rd top ace of the Japanese Navy. The navy stopped crediting pilots with kills at some point (1943???), but the US creditied him with about 63 kills. He set the record for edurance flight in a Zero; Never lost a wingman. He was badly wounded after mistaking a formation of Avengers for Dauntless (I think) and got shot up badly by the rear gunners. Bleeding from chest, head, arms and leg, and blind in 1 eye, he managed to reach an airfield and land over 4 hours later. Still blind in 1 eye, he was allowed to return to combat 2 years later.
AFAIK, the Axis countries had a very different approach to the Allied countries.
American "aces" would be rotated to help train new pilots. While the German and Japanese approach would be to keep the aces in the front line.
I couldn't tell you how experienced Germain pilots were are the start of WWII, but I imagine they had gained experience and developed tactics thanks to the Spanish Civil War. They certainly weren't using the WWI type of tight "V" formation the RAF fighters were using right at the start.
Japan had gained a lot of experience against China, and had a small force that was heavily trained. Over 1000 hours in a fighter wasn't unusual.
In comparision, the American pilots were numerous but poorly trained. I'm sure I have read the the average US pilot, in Dec '41, had about 19 hours flight experience, but that could just be bollocks. Regardless of the number of hours they did have, the weren't a match for the Japanese pilots. Saburo recalled coming across a flight of american fighters, and at least 1 pilot was able to trim his aircraft properly and it was flying "crab-wise" across the sky.
The Batte of Midway cost Japan about 300 experienced pilots. Rather than take remaing experienced pilots of the front line and use them as instructors, training times were reduced. Mean while the best pilots were slowly killed in combat.
Before Midway, America had started to invest heavily in training their new pilots, using their best and most experienced fighter pilots, the "aces" as instructors. Midway did not impact the training of new pilots. By '44, the average American pilots new into combat would have had 300+ hours, and training from the best that could be found, while his Japanese counter-part would have had only 100 hours, and not from the best. The situation was reversed and the Japanese pilots were no match for the Americans.
