what about from an allied POV though?
Allied POV might work if Germany is on the defencive (not very common), but Japan has outgrown US economy but not taken India. (happends alot, especialy with kgf or balance)
Allies need to keep Germany from activating Sweden (might be the easiest to isolate), Spain (easiest to attack) and Turkey (big UK army from 2IC in Egypt and Persia?). Goes without saying that allies attack land in africa and south america to boost their economy.
Im not saying its usualy a good idea, but it might be a plausible strategy to get that little extra IPC that stops Japan from winning pacific side. (Japan gains nothing if allied DOW neutrals, unless they pick up Afgahnistan.)
Now Cow sure is comming to trollpost me, no dubt 😛
