Hey!
I actually live in Japan, but it's not a recent move, so don't know if that helps... In the beginning it was hard. I didn't like the local food (no sushi!!)
These days it's not really an issue, perhaps only in terms of calorie counting, as the requirements of nutritional fact information are different, that and I can't get a lot of the products that are marketed as "diet friendly" in Europe and the US, although recently I see this as a pro and not a con. Besides, the locals have their own diet concoctions!!!
Moving abroad has a lot more implications in terms of physical and emotional stability and perhaps ability to communicate and integrate yourself in a new society than food does, at least it's been my experience in the 4 countries I've lived. Also, as long as you have the finances, you can eat like back home in most advanced countries...
Do you live in a big city?
