Why Japanese cities are such nice places to live

Japanese culture plays a huge role as well. Cities are a reflection of it's inhabitants, the cities in Japan (that I've been to) are quiet, organized, and clean.

You can walk through the residential areas of Funibashi (east of Tokyo) in the evening and hear a pin drop. It's a challenge to find a piece of trash on the ground.

What does, say... Philadelphia say about it's inhabitants?

You can also bike nearly everywhere, and for everything else there's exceptional public transport via trains and busses.

If I could live anywhere, in the world, out of all the countries I've been to, Japan is right top of the list.
