As cities turned into metropolises and metropolis became megalopolises, space became incredibly valuable. It is no small wonder that some travelers are deciding that they don't want to pay extra for a walk-in closet in a room they'd use for one night. The logic is sound even if the results can be quite confining.
The world's most famous tiny rooms are, without a doubt, the cubbies offered by Japan's capsule hotels. Though they make the list, what may be more interesting is the rooms they've inspired, which seek to combine their efficiency with the comfort of decor less reminiscent of the inside of a toaster oven. These are the next wave of micro-suites:
Nakagin Capsule Tower, Tokyo, Japan
The Nakagin Capsule Tower in Tokyo's Ginza district is notable not only for its tiny rooms but for its unsettling, distopian facade.
The Jane Hotel, New York, U.S.
New York's Jane Hotel combines cozy with compact by offering travelers "cabins" reminiscent of rooms on a yacht, with wood panelling, dark interiors and bunk beds.
Capsule Ryokan, Kyoto, Japan
Kyoto's Capsule Ryokan combines the relaxation of the spa experience with the anxiety that comes from sleeping in a toaster oven. On the plus side, it looks like a futuristic prison.
Yotel, Heathrow, London, UK
Heathrow's Yotel is designed to help travel weary fliers get some sleep before the next leg of their trip. The lighting and compartmentalization might lead travelers to believe they've been placed in a refrigerator.
Sleepbox, Moscow, Russia
Installed in a Moscow airport, the "Sleepbox" is a modular dorm room designed to help travelers get a little shut eye while waiting for the final boarding call.
CitizenM, Amsterdam, Netherlands
The rooms at CitizenM, a hotel within Amsterdam's Schiphol International Airport, are slightly larger than the other rooms on the list, but notable because they make use of every last inch of space.
Snooze Cube, Dubai, United Arab Emirates
Like several other tiny hotels, Dubai Airport's Snooze Cubes are built around the needs of travelers. However, they lack the charm of some of other tiny habitations. Probably better to sleep in the terminal.
