Abstract
A drastic decline of fertility has alarmed Japanese society and it also means reducing housing market. In this paper it is assumed that preparing comfortable living environment for child realing family becomes one solution to solve declining fertility. Thus making a comfortable living environment for child realing family is a big task not to reduce a housing market. And to do that, it is necessary to introduce marketing concept to urban planning process. The concept is that customer's needs are different depending on sex, ages, living conditions and etc. and it is necessary to check their own needs.
In this paper, it is examined that own needs of child realing families are not checked through urban planning process. And then a new method of urban planning is proposed which encourages to check own needs of child realing families and also confirms acceptability of the proposed method.
