Well that depends what you want from Japan. I mean you may get very lonely out on your own. It depends if you want that form Japan ! most people what the fast life from japan , running past japanese girls through the bright neon lights ! Again it would be much harder for you to get a job like on a farm out of no where , then geting one in a city in Japan.
The people around these area dont usually speak english, but i guess that isnt a problem really, but you prob get lonely quick
