In an isolated world, companionship is at a premium

via Futurescoping:

A Japanese cafe concept that’s become quite popular is the pet cafe, where stressed locals can gather to enjoy a meal, a beverage, and some relaxing companionship with a rabbit, cat, or dog. Since many rented apartments in Japan do not allow pets, these cafes offer a safe haven for animal adulation. One example is the Usagi-To Cafe in Nagoya, which is a rabbit-themed establishment that features decorations, toys, and food prepared in the shape of a rabbit (although the rabbits themselves are not on the menu). Since quality pet time is a commodity in Japan, there is an entrance fee and per minute charge.

You can also bring your own rabbit to socialize with the in-house animals, should your pet need time to mingle with its own kind.
