I ask this because there seems to be a widely-accepted consensus on this site about what a realistic Nazi Germany scenario looks like: with a POD in 1940 or 1941, the United Kingdom is forced out of the war, the United States never enters it, and the Wehrmacht steamrolls through the USSR. German dominance is achieved from the Atlantic to the Urals, and some sort of Cold War likely starts between Berlin and Washington. Sure, some of the details are still up for debate (How much does Italy expand its empire in the Mediterranean and Africa? Does Germany reestablish any overseas colonial presence itself?), but the scenario I just described seems to be what most people have in mind whenever this topic is brought up.
That said, inasmuch as the topic is discussed, there does not seem to be anything close to a consensus on the implications of a Japanese victory in the Pacific War. Part of this seems to stem from a belief that any sort Japanese victory was just much less likely than even a German victory - that even if America stays out the European conflict, the Pacific War will still likely break out and run in parallel.
So, imagine a scenario, with a point of divergence in the late 1930s or early 1940s, where Japan and the United States never directly come to blows. Realistically, what is the best case scenario for Tokyo in terms of the amount of territory they can annex or bring into their sphere of influence, then hold for any amount of time? Geopolitically, what would be the implications for Asia, the Indian Ocean, the Pacific, and the entire world? How does history unfold up to 2019? Assume, for the sake of discussion, that this is also a generic Axis victory scenario in Europe in the manner described above, simply because it means that Japan would not be totally diplomatically isolated.
And for a topic that is even less commonly discussed, what implications would such a scenario have for Japanese society?
