Japan? Been there for holiday once and that was during summer. I can tell you how hot it is, nothing different than Malaysia, no air con cannot tahan. Maybe Hokkaido won't be that hot.

Trust me, you won't like working life there. The MRT is totally like sardine lol. Somehow, working life in Japan is quite hectic, your employer will be very demanding as most Japanese demand things to be done perfectly, mark my word 'Perfect'. It is better that you work somewhere the currency is higher so that you can go for a trip to Japan. Having holiday over there is different than working over there. Oh yea, don't be surprised if you see convenient shops selling adult magazines. I seriously have no idea how to live over there especially if you need to raise your children there. So, working temporarily or studying = OKAY, living there permenantly = IS A NO NO for me :]

Many of you here are still young. If you have a chance, can try to apply for a working holiday visa in New Zealand which entitles you 1 year of entering New Zealand and engaged in paid activities (working).
