In this Monday, Oct. 29, 2012 photo, manager Akiyoshi Kaneko stands by the rooms at the Capsule & Sauna Century Shibuya in Tokyo. The capsule concept has been around for at least 30 years, starting out as lodging for businessmen working or partying late who missed the last train home and needed a cheap place to crash. But budget travelers and other folks curious about a unique lodging experience use them too. (AP Photo/Shizuo Kambayashi)
