In Korea, lots of people live in Jjimjilbang (http://en.wikipedia.org/wiki/Jjimjilbang). It's like getting a gym membership, but without the gym and with much more options for washing. You also get all the benefits that an internet cafe has to offer (connectivity, snacks, etc.) but without having to curl up in a tiny cubicle.
It sounds like the Jjimjilbang are more kind of mini arcologies with a heavy cultural overtone. Actually, kind of nice (not that I'd want to live there, but still).
