The purpose of this study is to examine the factors that determine whether the married women with an infant will continue full-time employment or not. Though most of existing studies on the career choices of married women focused on the different tendencies among districts, each found different explanation variables (hypothesis). We use every explanation variables (hypothesis) to decide which really has influence on their career choices. The explanation variables (hypothesis) are the rate of cohabitation of three generations, the sufficiency in capacity of nurseries, and separation of home from work explanation. According to the rate of commuters'outflow, we classified the metropolitan areas into three groups : the central, the suburbia, and the other areas. Among married women in the metropolitan areas, just one out of ten continue full-time employment as a whole. Binomial logistic regression analysis yields that living with parent (s) is the only effective way for the married women to coincide full-time employment and childbearing. In other words, social support for child-care centers and their personal strategy have no effect on increasing continuous full-time employment of married women.
