Still not sure that adjusting HI cost / levels will solve the severe supply problems.
To me it seems that the increased number of ac, ships and troops cost more supplies than Japan can afford even when at optimum strength.
Probably this is because lack of testing for late-game, although I do not recall other AARs, where Japanese side reported shortages.
Considering, that there is rare combat action here, your supply usage is very low. Shortage could be because you increase your industry, or maybe lack of extra conquered China industry cause this?
Attacks in New Guinea - New Britain - Solomons can be made by Allies with LBA support.
Same is true to a certain degree in Dutch East Indies but not sure Andy wants to have another go here.
- Pretty sure he will return to Port Blair, but he needs a Navy to do so.
Strategic Map
You do not point Kuriles, as possible invasion spot.
New Guinea seems to be in stalemate, was there any more action on western coast so far? Lack of action here, and in Burma could indicate, that those theaters are not on the list right now.
I am actually wondering about full invasion on Java. Considering, that Allied fleet is not in great shape, quick invasion of several bases, on large island - so they can be supported by land links, could release fleet from longer engagement.
Overall - Allies should now strike either against your oil routes, so west/south DEI willl be quickest, or directly against your industry, so Kuriles or Jimas. Although islands can be easily closed by your fleet, so large islands are more probable.
And, why the heck, late CVEs arrive with CLAUDEs?
