From Wikipedia, the free encyclopedia
A one room mansion(ワ) is a Japanese apartment style in which there is only one small room (10 m² (109 ft² or 10 ft by 11 ft) in many cases) and usually a compact bathroom. These styles of units are most often rented by single individuals due to their extremely small size which make 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 in size) are more common, especially in Japan's suburbs.
