Yep, that is right.
Westgate is offering you a contract for 1 year at a University or Universities teaching conversational Japanese for a whole 200,000 yen a month...and a bonus 100,000 yen for finishing the contract! (...and you thought 250,000 yen a month was bad)
Ad is at GailinPot if you find this hard to believe.http://www.gaijinpot.com/job_view.php?jid=28349
To be honest, they do not state the contact hours.
