LOLZ Knight. I don't like to say I'm "religious" since Christianity is a relationship with God, not technically a religion which sounds sorta one sided. But if that guy was Christian, yaaaa I'd try and make it work XD
The primary religion in Japan is Shintoism, with Buddhism following as a close 2nd. Christianity isn't that big there, but there are Christian churches and Christians there, it's just hard to find them.
