• One room mansion
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 m2/3.0 tsubo; 110 sq ft in many cases) and usually a compact bathroom. It is a functional equivalent of the Western-style studio apartment. These styles of units are most often rented by single individuals due to their extremely small size which makes it hard for more than one person to reside in them. Most of Japan's city apartments have rooms such as these although family units (around 60 to 90 m2/18 to 27 tsubo; 650 to 970 sq ft in size) are more common, especially in Japan's suburbs. Also, One Room Mansions contains more goods than other houses.
