Thanks Fratemate.
Re the wife visiting i was more interested in knowing if she visits you after you are checked to line and flying and having your normal 9/10 days off will you have to leave the country then as a part of your contract or can you remain in Japan with her.
I understand that you cant technically live together in Japan but if she is there on visits of up to 3 months do you have to leave every month during your days off.
