I can't run the game it keeps getting this errors
Some files are non-unicode.
The easiest solution for you (if you use Windows 10) would be to go to your Windows settings, then select Time & Language, select Language, on the right side you should see "Administrative language settings" click that and finally you should see "language for non-unicode programs" hit the button that says "change system locale" and set it to Japan.
But make sure you downloaded the Japanese language pack for your Windows first.
Actually better yet here is the tutorial:
