This is the most hilarious thing ever XD Sarcasm right? ....right?

Um... anyway, I haven't lived in Japan myself either, but I would think that being shy would make living in a foreign country more difficult than the one you were born in. From what people have told me living somewhere where you don't speak the language and most don't speak yours is a quite an isolating experience, and one that takes a lot of effort and putting yourself out there to overcome. I can imagine it would be very lonely if you're not capable of doing that. Unless you're the type of person who grows well by being forced into sink-or-swim, uncomfortable situations I'd say that moving away is not going to help your self confidence issues.

Japan is great, but can be tiring. Also, while most people are very friendly, there is a certain smugness to it all... For example, many will smile at you but won't be smiling to you.

But, I'd say the majority of people there were more polite to me than the average American here. But, if you need to go to school or anything like that, I'd take care of all that first. I made the mistake of going there without any education and I had a rough time for the last half year I was there.
