Land in Tokyo is a much prized possession, and as such, people have to pay a pretty penny to purchase some. A situation that means even the most meagre amount of land is likely to be built upon, making monolith-like lodgings a must.

have a certain sense of style,
and conveniently boast just enough space for a suitably sized car.
