Each room can be used by the hour with a minimum mandatory use of three hours.

Unlike conventional capsule hotels, the rooms have full-size beds as well as a shower. Prices vary from 7,000 won to 11,000 won ($5.95-$9.35) per hour, depending on the size and type of the room, with some big enough to accommodate a family of three.

"The capsule hotel Darak Hue has been developed to improve the convenience of transit and late-night passengers at Incheon airport, which operates 24 hours a day," the ministry said.

"The launch of the capsule hotel following an expansion of restaurants and stores that stay open overnight will greatly improve the convenience of transit passengers and those coming to the airport from the rural side of the country to travel, who may need a place to rest due to their late arrival or departure," it added.
