Capsule hotel, also known in the Western world as a pod hotel, is a type of hotel developed in Japan that features many small bed-sized rooms known as capsules. Capsule hotels provide cheap, basic overnight accommodation for guests who do not require or who cannot afford larger, more expensive rooms offered by more conventional hotels.
Located in Kita within a 5-minute walk of HEP Five Shopping Mall, Capsule inn Osaka is within a 15-minute stroll of Hankyu Umeda Main Store. This 415-room capsule hotel welcomes guests with conveniences like a restaurant, a full-service spa, and free in-room WiFi.
The first capsule hotel in the world, Capsule Inn Osaka (New Japan Umeda), opened in 1979 and has been enticing guests ever since.
Designed by architect Kurokawa Kisho, the Capsule Inn Osaka is the world’s first capsule hotel, a form of lodging now widely regarded as no less quintessentially Japanese than the ryokan. At that point Kurokawa had already been advancing capsule as an architectural unit for years, contributing a “capsule house” and capsule-based corporate pavilions to the Osaka World Expo 1970.
The sleeping capsules at Osaka Capsule Inn are placed side-by-side in a common area. Each has curtain for sake of customers’ privacy, an alarm clock and a TV. Bathrooms and toilets are shared, with free toiletries and shared-use hairdryers. Only men can stay at this property.
