Fantasy life, the new drug we all need

This game sounds neat and I might get it, but I'll be getting it on my New 3DS LL, which is obviously in Japanese, versus my room mate, who will be getting it on his American 3DS XL. Anyone know if we can still play together and that there won't be any kind of region separation? I wouldn't assume there would be, if local wireless is available, but I know that they have internet play for it.
