Coffin Hotel in Tokio

Capsule hotels in Japan are popular with local businessmen who miss the last subway home at night, or are too drunk to make it home on their own.
Gangsters, students use them, and low-budget travellers use them too.
One night sleepover? Just pay around US$30. Tiny sleeping capsule with flat-screen televisions inside.

This style of hotel accommodation was developed in Japan and has not gained acceptance outside of the country. The Japanese capsule hotels vary widely in size, some having only fifty or so capsules and others over 700. They are often used primarily by men. There are also capsule hotels with separate male and female sleeping quarters. Clothes and shoes are sometimes exchanged for a yukata and slippers on entry. A towel may also be provided. The benefit of these hotels is convenience and price, usually around ¥2000-4000 a night ($25–34, €21-29, £15–20). Such hotels are not necessarily regarded as only an option for those with lower incomes— a typical customer would be a business salaryman, someone looking for a place to stay after drinking, or a someone who missed the last train and doesn't want to waste money just for an overnight sleep. Some capsule hotels offer low daytime discounts for those needing an afternoon nap or other mid-day hotel accommodations.
These rooms can be seen in the movies The Fast and the Furious: Tokyo Drift and Gung Ho. They were also used as a basis for sets in the film The Fifth Element. They also appear in the cyberpunk novel Neuromancer under the name of "coffin hotel."
