Claustrophobic apartments

Japan's itty-bitty-tiny spaces.

These coffin-sized apartments in Japan cost $600 a month to rent. For perspective, most cubicle spaces are larger, and definitely have more leg room. These tiny spaces are stacked on top of each other, without windows or doors, but are designed for professionals who spend most of the day (including meals) out and about. Think about these next time you complain about the size of your place.
