Entrepreneurs in Tokyo have developed "capsule" hotels with coffin-like cubicles for those needing shelter. They aren't free:
The rent is surprisingly high for such a small space: 59,000 yen a month, or about $640, for an upper bunk. But with no upfront deposit or extra utility charges, and basic amenities like fresh linens and free use of a communal bath and sauna, the cost is far less than renting an apartment in Tokyo, Mr. Nakanishi says.
The concept was originally developed to accommodate travelers in airports or those stranded without transportation, but now they are being rented by the month, and long-term users are registering the sites as their official "home."
