Pros
If you've never been to Japan before, this would simplify the process (but at a cost!).
Cons
This is a greedy, unethical company, and should not be mistaken with a bona-fide educational institution. The staff (both Japanese and foreign) are dishonest and unscrupulous, and will gladly toe the company line to receive their paycheck. You are forced to use the totally overpriced housing, are required to endure grueling and unnecessarily long commutes, receive a low salary with no benefits, and the teaching itself is nothing more than standard (and often silly) ESL, not university instruction. As part of their ongoing ripoff campaign, Westgate recently switched to paying on an hourly basis (rather than a monthly salary), which guarantees that you don't even get paid for the occasional national holiday. You'd be much better off, and better paid, working for one of the many ESL chain schools. Avoid Westgate like the plague.....
