i guess that depends on what kind of duel you play OR the tournament organizer's decisions?!

i can't remember a chapter in the english rulebook that would forbid use of jp. cards...

at least ask your fellow player if she or he is ok with your jp cards because you sure must be able to show the accurate translation(s) of those cards during the duel.
