 The Japan Housing Corporation (JHC), now known as the Urban Renaissance Agency (UR), was founded in 1955.During the 1950s, 60s, and 70s, the JHC built many "danchi" in suburban areas to offset the housing demand of the then-increasing Japanese population.A traditional Japanese house does not have a designated use for each room aside from the entrance area ("genkan," 玄関), kitchen, bathroom, and toilet.
