Living in cities has its perks and downs at the same time. But if you're eyeing to live in a city like Tokyo without a substantial budget, you may be facing one of the surprising downs of urban lifestyle: the coffin apartments.

According to Kotaku, there are now share houses that put a whole new twist to the word "extreme" living. Instead of a small, cramped apartment, where you barely have any space for an extra table, here you may not even have the space to stretch your legs.

What's the outrageous of all is the fact that these spaces are rented out at $600 to even $1,000 every month.

According to CNN, this amount is considered to be cheap, especially when the night rate is still below $50, supposedly the going rate for a housing bargain in main Tokyo.

Built similarly in the same way lockers are stacked up on top of one another-they do look like lockers from the outside-these Japanese coffin apartments would challenge your creativity in packing the space with your things, without getting buried in them (literally).

Japan has long battled the problem of overpopulation, which is why "coffin" apartments like these has been attracting students and the working population who need easy access to urban lodgings for sleeping, but spend the rest of their time outdoors, reports CNN.

In fact, given the population and the area that can be occupied by housing developments, the problem of overcrowding has already pushed the more innovative thinkers and developers to resort to other means of offering housing solutions.

JapanProbe reports narrow housing has become a good way to build your own house without the challenge of shelling out too much.

In one resident's experience, he had a house built with less than 2 meters in width-narrower than the space between two houses in other countries.
