The guest room is a modular plastic or fiberglass block roughly 2 by 1 by 1.25 m (6 ft 7 in by 3 ft 3 in by 4 ft 1 in). Facilities differ, but most include a television, an electronic console, and wireless internet connection. The capsules are stacked side-by-side, two units high, with steps providing access to the second level rooms, leading to comparisons to corpse drawers in amorgue. The open end of the capsule can be closed, for privacy, with a curtain or a fibreglass door. Luggage is stored in a locker; and washrooms are communal. Guests are asked not to smoke or eat in the capsules. Some hotels also provide restaurants (or at least vending machines), pools, and other entertainment facilities. Capsule hotels vary in size, from fifty or so capsules to 700, and they are used primarily by men. Some capsule hotels offer separate sections for male and female guests. 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 low price, usually around ¥2000-4000 (USD 19-38) a night. They provide an alternative for those who (especially on weeknights) may be too drunk to return home safely, or too embarrassed to face their spouses. With continued recession in Japan, as of early 2010, more and more guests - roughly 30% at the Capsule Hotel Shinjuku 510 in Tokyo - were unemployed or underemployedand were renting capsules by the month. This style of hotel has not gained wide popularity outside Japan, although Western variants known as "pod hotels" have been developed, with larger accommodations and often private baths.
