Historically the Xbox brand's sales have been negligible there and the console market cratered a while ago.
Did you even read my post. It's still the second biggest market or maybe 3rd if you only count home consoles.
Also Japanese games are very popular in Europe especially france so just quitting in Japan also limits your sales in Europe. Asia and the middle East also play alot of Japanese games. Unless MS only cares about the US they need to maintain some semblance of Japanese support. Even in the US their is a pretty good market for niche Japanese games.
