Exactly, just like Tokyo, one of the most expensive cities in the world

Cost to rent a typical 2br apartment vs. population density.

* City A: $1,903/mo, 6,158 persons / km²

* City B: $3,685/mo, 6,659 persons / km²

Can you guess which is Tokyo (prefecture), and which is Hong Kong?

Another fun data point: Seoul is ~16,000 persons/km² with rent around $1100/mo.

I’ve been searching all over and I can’t find any evidence that any Japanese cities are among the most expensive, when looking at housing costs.

Can you please share your sources?
