Australia! Oh, wait, I'm already here... Must be wearin' mah red shoes...
Well, if for some reason I was daft enough not to opt for Australia, my second preference would be either Wales (I STILL regard it as a seperate country! Yes, I'm Welsh anti-royalist heritage ), Ireland, Germany, Argentina, Spain or, yes, Japan.
I'd choose Japan for the reasons Tomamil won't; I like to be left alone.
Plus, I speak the language and have a keen technological interest - major industry in Japan.
It's also not a third-world country; always a plus.
