For a data point: (admittedly, barely) inside Tokyo 23 wards, 15 min walk to nearest station, 70 sqm (753 sqft) 3LDK (3 bedrooms and a living-dining-kitchen). 140000 jpy / month. (945 usd at the current rate.) I think it's a reasonable deal. Less or similar than I would pay for a similar flat in my native Helsinki, Finland.
