Capsule hotels are a phenomenon especially popular in some Asian countries, like Japan. They are a less expensive alternative when compared with ordinary hotels - especially in an expensive country like Japan. They also have a capacity to accommodate way more people. When you look up the definition of a capsule hotel on the Internet, it says that it is a type of a hotel that has a large number of very small rooms called capsules. But this is not entirely true. The capsules are nothing more than a bed surrounded by walls and a ceiling. They offer more privacy than a normal dormitory in a hostel, however to call them a “room” is an exaggeration.
