This paper considers the situation of the family in contemporary Japanese society through an analysis of change in the unilieal continuity which characterized ie, the traditional form of family structure in Japan.
The change in unilineal continuity of family tradition is measured in terms of the following three characteritics; (1) consciousness of the unilineal continuity of family tradition, (2) consciousness of the successor to family tradition (atotsugi), and (3) the role of the successor to family tradition as related to the division of labour and the decisionmaking process within the family.
The following results were obtained. First consciousness of unilineal continuity remains strong on the whole, and especially from the view point of ancester worship, a symbolic cornerstone of family tradition. However from other perspectives, the consciousness of unilineal continuity has been changing subtly toward the modern pole. Secondly, with regard to the consciousness of the successors to family tradition, there are remarkable differences between the elder and younger generations. In the parents' generation the status of successor to family tradition is considered to be combined with the unilineal continuity of family tradition,but it is inclined to be conceived of in the conext of filiation by the childrens' generation. There are many more chances for the elder brother than the younger brother to become the successor to family tradition. In this, traditional characteristics continue to be shown. Thirdly as for the diviaion of lavour and the power to make decisions in the .family, it was found that the role behavior of the successor to family tradition is not much different from the traditional pattern. As for the division of labor in the domestic domain , the successor to family tradition does very few household chores and the division of labour by sex is clearly dominant. As for the power -to make family decisions, the asssignment of power by generation between the head of the household and the successor to family tradition is dominant.
