This study aims to understand housing situation of Single Mother Households who are divorced or widowed in Japan. Recently, the greater rate of divorce or separation caused by changes in lifestyles and social status for women have been contributing to the growing number of Single Mother Households. However, these families are facing difficulties in seeking to be economically and socially independent As their income is just a fraction of the general households, under the profit-oriented housing provision, it is hard for many of them to own or rent housing because housing expenses for housing are still much of a burden for single mother households to bear.
