In regards to the mansion type personal housing that people are expecting:
A one-room mansion (wan rūmu manshon ワンルームマンション) is a Japanese apartment style in which there is only one small room (10 m[sup]2[/sup] or 3.0 tsubo or 110 sq ft in many cases) and usually a compact bathroom. It is the functional equivalent of the Western-style studio apartment. These units are most often rented by single individuals due to their extremely small size; it is hard for more than one person to reside in them. Most of Japan's city apartment blocks have rooms such as these although family units (around 60 to 90 m[sup]2[/sup] or 18 to 27 tsubo or 650 to 970 sq ft in size) are more common, especially in the suburbs.
Japan sees it differently.
