Is there any way to stop Japan taking random European states in the WKII when they’re only fighting in Asia (and usually losing at that)? I admit I’m not knowledgeable about how this is programmed, but I can’t think of any other nation that will take literally any coastal land it can and then more from there.

You end up with Japan holding Crimea and a bunch of adjacent states and random Baltic things, and that breaks the scripted events for releasing nations half the time. That or ignoring the Russian pacific coast to take bits of Siberia through Archangelsk.

Like 9/10ths of the random border gore in Kaiserreich is Japan’s fault, and they still don’t take China.
