This study focused on issues of relative importance to the work and family life of married men. The work was carried out to determine, when men are in any category, how to increase their satisfaction with their work and family life. Data from 896 married men with their youngest children under 18 years of age was collected and analyzed. Cluster analysis was performed to classify the categories depending on the relative importance of work as compared to family life. I obtained four types relating to the relative importance of work compared to family life. The results are as follows. First, the score of subjective balance which was perceived by the men was slightly higher than the normal range, at 3.27 points. Second, work-family negative spillover is bigger than family-work negative spillover. On the other hand, family-work positive spillover is bigger than work-family positive spillover. Third, in the category in which the difference is largest between the relative importance of work and family life, the men crave the value of nonwork. It seems that in order to bring a particular gravity to work, there is a possibility that the areas outside of work will be suppressed. Also, in this category, both the satisfaction of family life and job satisfaction were low; this will be a point to consider when discussing the problem of the balance of work and family.
