If I could work in Japan I would in a hart beat. Japan is great, awesome food nice folks great baths (onsen). Osaka life is comfortable, a bit hot and humid in the summer. Don’t know about the Dash 8 but only did hear good things. The cash flow, as mentioned isn’t the greatest, but if you're young and single its enough to have fun, plus you'll get (perhaps) a chance to clime the ranks on ANA. Good luck!
