Re visibility, there's the same answer as above. It depends upon what you are used to. The USN was very late to respond to the value of all-round vision, and the British had no such types in the far East until postwar. Even the USAAF had a majority of high-back types in the Pacific war, until the very end. When you're winning, what you aren't used to you little miss. Whereas the Japanese pilots were almost entirely used to 360 degrees of view, barring a small minority from Ki.61/early Ki.100 aircraft, so can only be expected to notice the shortcomings of the high-back Raiden in this respect..
