Yes, the numbers are a bit skewed by the fact that more people live alone in Tokyo than Paris or NYC, but it's definitely true that you get more square meters per $ in Tokyo. Also, it is true that people on Tokyo on average earn less than NYC, London and Paris, but they also spend a smaller percentage of their total income on housing, so housing is cheaper in PPP terms too. I'll dig out the exact numbers tomorrow if anyone is interested, but now I'm out in one of Tokyo's extremely cheap bar districts having skewers and beers for less than $10
