Capsule hotel
The Japanese have been made famous for many things, but one of them is the capsule hotel. It is something that people in western countries look at as different and more of a novelty, but in Japan, it’s serious business. People really do use these hotels and they make a lot of sense as well.
Most cities in Japan are very congested and space is always a problem, so to tackle that the idea of a small capsule with just a bed seemed to make sense. Also, for those who are just staying overnight somewhere and do not want to spend big money on a hotel room, why not.
