A 60m^2 apartment just around the periferies of the center of tokyo (I'm talking 10 minute train to Shinjuku) costs about 700k in dollar terms[0] if you want to buy it, and between 1500 to 2000 per month if you want to rent it.
Move further away from the center, and the cost drops dramatically. A house near a station that's 30 minutes from Shinjuku the same size above costs half the price (~350k).
[0] If you think about a 100 Japanese Yen as 1 "Japanese Dollar". It's not equivalent to 1 US dollar, but if you adjust for typical salaries and cost of living it comes out about the same, when you are considering the price of housing, etc.
