I assume that you mean that they will be offering services online as well?
As a European I expect - well, nothing, unless its gambling license is based on Malta.
Many poker sites facing Europe have managed their gambling licenses in a way that the winnings are tax free for us. So playing on a site that is probably licensed only in Japan is not that attractive to us.
For Americans the gambling options are (and for long time have already been) very limited so Japanese site would not be very interesting to them either.
