Dude the whole world is like that, it's called civilization. But it's cool if you're a hermit. America is of course, much more than Miami, Texas or Las Vegas as Japan is much more than Tokyo.
lol, where did you hear this? Any long termers in Japan who have a kids know that's pretty far from the truth. Sure if you want to live a hermit life with no kids, no wife and don't want to speak Japanese than it's what you're looking for. The reality is that citizens are expected to do a lot of stuff, all that PTA stuff. I'm greeted a few times every morning on the way to my car by the mansion staff who are always too happy to share with me the mansion news. The simple fact of the matter is that the nicer the place you live the more you stand out as well. We're all uppity that way. Just in order to rent a place in Japan you need a Japanese person or company to co-sign for you, unless of course you want to live in a dump.
My advice, stay where you are, life is easy for you. Just learn to deal with people and grow a thicker skin. Work on your "death stare".
