Japan is one of my favourite places. You'll never find a safer, cleaner, more polite, and orderly country in the world. It's full of wonderful contrasts from zen gardens to Electric City. And all of these contrasts are arranged neatly. I honestly don't recall anything being out of place during my time there. The zen gardens are famous for having nice lines in the pebbles of course, but this OCD (perhaps) goes all through the Japanese culture. And actually I quite like it.
