Well he's half japanese and before he came (to get his master) he lived there for 11 years. Also, he only needs to pass one more test and he'll be able to teach the martial art . He takes ninjutsu veeeeery seriously (he doesn't like to call it ninjutsu since it attracts people that only want to practice it cause of the "stereotype") and one of his plans is to open a dojo in the future.
Anyways, we are living in New York City already, theres not too much difference on expenses between here and Tokyo.
Fiero, I've done a couple of martial arts and this one is my favorite. I highly recommend it.
