It's reminds me of the lifestyle of the (anti-)hero of William Gibson's seminal novel Neuromancer.
One striking feature is that anyone who tried to live in an internet café in London, Paris or New York would have their meagre possessions stolen within days. Japan has such a strong shame-culture ethic they don't have those worries. In Tokyo you can find food- and cigarette-vending machines on street corners made of such flimsy plastic that they could be ripped open using muscle power alone. They'd be cleaned out within 24 hours anywhere else. The Japanese have also pioneered those capsule hotels that look like they should be on a submarine or spaceship rather than planet Earth. (There is something dinky and cute about them mind!) This is what the future looks like . . .
