The first capsule hotel to open was the Capsule Inn Osaka, designed by Kisho Kurokawa and located in the Umeda district of Osaka. It opened in 1979. The guest room is a modular plastic or fiberglass block roughly 2 by 1 by 1.25 m. 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. 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.
