If the game doesn't launch there's a simple solution, go to settings, time and language, then click in language, and click the first option in the right corner marked as blue called "administrative language" or something like that then you need to change the unicode or regional language to japanese, restart the pc and done, note: this only changes the code language in Japanese it doesn't harm or damage windows, also your language is going to still in english or your native language, what changes is the code language because windows detects alot of japanese letters as "?!?#" etc
