I follow the Japan contracts and the Skymark pay seems a bit low to me. Captain pay there is similar to FO pay at Qatar. IMHO, If you are single the money and allowances are enough to enjoy life and save some $$ too. If you are married and have kids its going to be expensive. I would go to QR if its money you want.
WASINC says the domicile is Tokyo but the other agencies are offering Kobe. If it is in fact Kobe, the Kansai (Osaka) area is quite nice and cheaper than Tokyo.

I commute to Tokyo every month and living here is far superior to Qatar, but stay tuned as I am moving to QR soon.....
