Optimizing the Most
In the big cities with good nightlife in Japan, such as Osaka (among many others), there is a very special type of hotel called "capsule hotels". They are made to optimize the most, and the client, instead of having a room, has a "capsule" that is, a carrier which fits one person laying down, with radio and television incorporated inside. Upon entering they give you a locker, where you leave your clothes and luggage (restricted amounts) and you wear a yakata inside (like a robe). Once inside, there is a TV room, vending machines for hot and cold drinks and communal showers. Sometimes there is also a sauna and computers to access the internet.
