Hi. I have a different scenario proposal, after reading Mad monarchist's article about the japanese "justifications" for their entry in the war, then I reached this part:
"Japan had actually been prepared, after years of fighting in China, to abandon the conflict and withdraw their forces to focus on the defense of Manchuria and consolidating the hold on northeast Asia that Japan already possessed. Had they done so, the Empire of Japan might still be around today."
So what would have happened if Japan in 1939, maybe by appointing a more isolationist PM, or due their economical situation, or just because of the hand of God, the japanese retreated from mainland China back to Manchukuo and Mengkukuo to consolidade their empire (maybe trying to negociate peace with Kai Shek) and preventing the pacific war
