Abstract
In this study, the relationship between the type of sleeping arrangement for couples and their marital relationship was discussed in connection with private space. The first procedure was to quantitatively examine the data (301 cases) which was obtained from questionnaire surveys. The second procedure was to qualitatively investigate 22 cases. Distinctive styles and requirements of dwelling or their marital relationship were examined for similar cases of sleeping arrangement. The results were as follows: 1) When couples have space and time for communication, their desire for private space appears to be reduced, but if it is lacking, private space is desired as shelter from trouble. 2) A master bedroom where intimate relations can be built up is important especially when children are being brought up.
