No. People NEED sunlight.

A lot of crazy stories come out of Japan. Cramming people into trains. Vending machines with used panties. Hordes of Crows. Hordes of bee to attack the hordes of crows. Suicide Clubs.
And now this. Is Tokyo really so expensive that people will do this to themselves? Or are the crows really that bad? From Boing Boing:

The BBC reports on a cyber cafe outside Tokyo that has a dark room divided into tiny cubicles where 60 people "who rarely emerge" live. These folks are called cyber drifters and "they have just enough money to stay off the streets." It costs $500 a month to live in one of these "coffin-size booths," which have no natural light or fresh air. "In Tokyo it doesn't get any cheaper than that, or more claustrophobic." The owner of the cyber cafe is making a tidy sum off the rent: 60 X $500 = $30,000
