They are very interesting. Overall, Japanese aircraft losses in the war were about 45000, of which the japanese say 17000 were to non-combat causes. Estimates for the USN flak kills are about 2500-3000. We dont have losses to ground fire from other sources, but surely less than 1000. According to GGs list, I count roughly 13000 to fighters. That leaves about 12000 un-accounted for , but most likely to two main causes: bombers and ground overruns. We know that the Russians claim at least 1700 captured in the very last days of the war, and upwards of 1000 in their air combats (making them the second highest nationality in the pacific). They also make what are considered spurious claims for pre-1941 losses in the japanese air forces of around 1000 aircraft. I dont have any information on chinese claims 1937-45. That leaves about 9000 to bombers and other causes, excluding chinese and early war Russian claims.
Of the 45000 over 5000 were expended as Kamikazes, and of these about 2000 were lost to flak (which rather brings the flak losses into question).
As you know Japanese losses are really hard to accurately pinpoint in that top down approach, and I dont have the detailed ground up knowledge that you or Joe have......but in a very rough and general way, I think these estimates roughly tally up
