My first choice would be Germany. I really like the small towns over there. My aunt lived on the outskirts of Heidelberg for a few years and the place is awesome. So quiet and relaxed, neat and orderly, shitloads of trees all over the place, good weather, supreme aryan ubermenschen everywhere, and fantastic beer!
I guess I'd like to live in Japan as well. It just seems like an interesting place to live. But given my fascination for Japanese females I'm afraid it would probably just turn into an extended bout of sex tourism.
I've often fantasized about living at my family's ranch over in Sonora, Mexico. I could probably go over and work there if I really wanted to but I sort of like having electricity, being around other people, etc.
