Capsule hotel (カプセルホテル, kapuseru hoteru), also known as "pod hotels" or more humorously referred as "coffin hotels" (term coined from cyberpunk novel, Nueromancer) are white compact fiberglass pods that are about 2m by 1m by 1.25m providing relatively comfortable sleeping room for travelers, businessmen, or people who are too drunk to get home.The size is a minimalistic design similar to airplane cockpits meant to preserve space but retain comfort. The idea was designed and used on February 1, 1979 in Capsule Inn Osaka by Kisho Kurokawa, the initial room rate was ¥1,600. Nowadays, the Kotobuki Corporation makes most of the pods and to rent a room today would cost from ¥2000 to 5000 ($15 to $45). Although Capsule Hotels are not popular outside Japan, variation have recently caught on and are starting to be used worldwide, such as in London, New York, Amsterdam, Lumpur, and Kuala.The hotels are usually opened 24/7 and are mostly broken down into two sections. The public sections are divided by the lobby, shower, sento bath, lockers, TV lounge with Wi-Fi, stores, vending machines and at times a restaurant or bar. The private sections are rows of pods stacked side-by-side on two rows which forms a maze of hatchets. The number of capsules varies from hotel to hotel where some may have about fifty and others may have over seven-hundred.When you first enter the hotel, you will find a small ticket vending machine. On the upper left hand side of these machines, third button over is usually in English. Second, insert the money and confirm your booking. The buttons will be labeled, "Short rest", "breakfast", and "clothes to keep". A ticket comes out and you would need to bring it over to the front desk. If there is no machine, then just walk over to the front desk and ask for a room. If you want, you can store your luggage behind the counter at the lobby or in your temporary locker. After handing in the ticket, a small yukata (similar to pajamas that you wear around the hotel), slippers, locker number, key, and sometimes a wristband, toothbrush, and a towel will be given to you. Walking down the dark corridor, you will find your capsule. Depending if it is on top or bottom, you can use a small ladder to climb on to the top one. Many noticed that it’s surprisingly more spacious than they first thought. With enough room to sit up and read, you can look around to see the pillow, blanket, and the thin mattress underneath you. To your right, you will notice a small control panel with quite a few knobs (or touchscreen). One button turns on the light, a knob nearby controls how dim the light is, another sets the alarm (which rings by default from 7 AM to 9 AM to remind people to check out), the one over controls the radio, and sometimes the capsule comes with a big red button that turns on adult entertainment, it’ll cost on average an extra ¥300. A little higher is a small shelf for extra stowing. Near the capsule’s entrance, at the upper right corner is a small TV hangs slightly above your knees. For some privacy, you may pull down a thin curtain above the fiberglass window.One major drawback is that most Capsules Hotels do not allow women for security reasons. The few hotels that do will generally partition a separate floor for them, such as the one in Akihabara district in Tokyo. Another drawback that people found is that they would like to have some control over the temperature. It may be hotter or colder than what they are used to. Nevertheless, these hotels are meant for short stays and every year they are booming more in popularity.
