MMM is right. You won't be able to get a job with an English-speaking company. However, if you could go there on a student visa, or even just on a passport for a month, you could teach people informally in a one-on-one tutoring session type deal. It would be harder to find customers, but you'd make much more money.

I knew a girl who made 10,000 yen (about $100) per hour to just do English conversation with businessmen, while they took her out to fancy restaurants to eat.
