If by "war" you mean any armed conflict in the Greater East Asia Co-Prosperity Sphere, then you have a chance for a scenario that does not include US participation. The prerequisite for any "victorious" (or even intact) Japan is no war with the US. If political and/or military actions bring the US into a shooting match, Japan is out. Maybe sooner, maybe later, but out. A couple of possibilities:
A sometimes suggested strategy of OTL's attacks on British and Dutch colonies but bypassing and not engaging the Philippines. Gambling that the US will not declare war if not directly attacked with the backup that, after successful occupation of the various European colonies, troops, transport and supplies can be built up to threaten or invade the PI into a status quo peace or at least an armistice. Sort of a Pacific "Fall of France" scenario, minus the BEF.
Second (possibly in combination with the first) is shifting the European/Pacific war timelines. If Japan attacks the French/British/Dutch before, say, the Danzig crisis bursts upon Europe, then the UK, France, and Netherlands may send expeditionary forces to deal with it all only to find Hitler suddenly deciding that the Polish Corridor is now a thing. Either a withdrawal or some sort of hasty armistice is needed to bring troops back to Europe for a feared big show. An un-attacked US may not be willing to start a war for colonies. Especially colonies that the Europeans have just abandoned, anyway (with interesting butterflies on the Atlantic Charter).
A couple of possibilities. Can't speak to probabilities, though.
