Capsule Hotel

Capsule Hotel refers to a type of hotel invented in Japan. A guest lies down in an extremely small "capsule" room, which only has enough room to sleep. Although they usually don't feature any luxuries like Onsen, they are popular with tourists and business people who just need a place to sleep. Shinjuku city of Tokyo has a lot of them, and you can find one in many other cities like Osaka and Kyoto too.
