The Japanese industrial base wasn't big enough to supply the additional skilled personel (even before the IJA started drafting them), and the machine tools availability and production line engineering skills and experiance weren't available either. So when production was pushed to the max, you wound up with things like a 30% rejection rate on areo engines.
But part of the problem WAS solvable: Parillo says the Army and Navy ignored each other's needs:
A plant making Navy planes would have a critical worker - and the Navy would not draft him - but the Army said "who cares" and drafted the guy anyway - so the plant loses its expert worker! Also, they put American POWs in shipyards! These guys regularly sabotaged the ships! One of these POWs said "I think they must do it for morale reasons - surely they know it isn't efficient." [In fact, about 2000 US soldiers died at Hiroshima - they were prisoners not in camps but in industrial facilities. Along with about 20,000 Koreans - people who were nominally victims of 80 years of Japanese imperial aggression and such good allies they were the main way we knew of things in the empire.]
The degree of NON-cooperation between the Japanese Army and Navy is almost impossible to believe. Someday maybe someone will do a really realistic WITP where the Allies are played by the AI and the players can compete as the REAL opponants..., the IJA and the IJN! Of course, BOTH of them were competing against their own Civilian Economy (as witness the military's shipping returning empty to Japan from the SRA---or putting the Civilian Population on "rationing" 8 months BEFORE the war started)
