Japan, which is why I've visited....7 times so far. There's just so much to love about it, it pretty much has everything you could want, advanced cities, but highly organized, great natural areas...incredible food pretty much everywhere, and friendly people in many places.
I'd really like to live there if/when I have the ability to do so. Yes, it's not a perfect country and it has a difficult work/life balance culture, among other issues like an aging population but I feel like they will solve those issues eventually.
