There's a new hotel in Kyoto (Japan) that's based on the concept that you only need 9 hours to rejuvenate. Guests at the new 9H Hotel check in, shower, sleep in a pod, refresh, and then leave. Presumably, all within 9 hours.
Each guest is allotted one hour to shower, seven hours to sleep and a final hour to rest. Each pod is equipped with Panasonic control panels for setting the ambiance. The building itself wis 9 stories tall, hosts 125 capsules, locker rooms, showers, and a lounge.
