I live in New York City and pay about $1000 a month for literally a 100 sq ft apartment. I have a very small room, and a roughly 4 ft x 4 ft kitchen (mini-fridge)which connects to a bathroom. I live in a very nice and convenient area of Brooklyn, so it's worth it because alot of people pay alot more for less, especially in Manhattan.
But what are rent prices like in Tokyo? The Japanese have a well earned reputation for being minimalist space-wise, so I imagine apartments as small as mine are not uncommon.
Also, what is the disparity in neighborhoods? In Brooklyn, for example, there are neighborhoods that you simply would NOT want to live in, on the basis of crime and, with gentrification pushing the poor farther and farther away from Manhattan, commute inconvenience.
Does Tokyo have its "bad" but cheaper districts? Could I, an outsider, live in them safely?
