Relic Castle

Basically, I want to have something like the Japanese tourist in Pokemon X and Y in my game with a Gym Leader originally from Johto. Only problem is, the default Essentials fonts don't appear to include the characters I'd need. Is there a Unicode or Japanese-optimized font available or some sort of workaround? I could just display the characters in Arial or something, but it'd be ideal if there were a compatible Pokemon font for aesthetic reasons.
