I have a couple of places I really want to visit, but Japan is at the top of my list =P
I love the culture, the food, the language, the women, the beautiful places, pretty much everything except that I heard the locals are a bit cold towards foreigners.
The only problem I have with going there is that the flight is over ten hours from my place and I get pretty nauseous after a 6-7 hours flight.
And in the future I think I'll move from country to country every couple of years or at least I'll try out some until I find a place I want to stay at (until I get bored of it too =P )
USA and Spain are kind of my dream countries (to live at), but it's more likely I'll first go live in India when I get the chance to move.
