In this study, we hypothesized that the psychological Ibasho, which arises in relationships with others, is a sense of unconditional affirmation of one’s true self and an adaptive sense of being needed by others. The purpose of this study was to examine the effects of individual desires and behaviors on Ibasho in order to obtain an understanding of how they functioned. We measured Ibasho, over-adaptation, rejection–avoidance need (desire not to be rejected by others), and interpersonal dependency in 146 university students.We then examined the validity of the model using covariance structure analysis. The results showed that affectional dependency and sense of self-inadequacy predicted the sense of role through an orientation to others. In addition, instrumental dependency predicted role sense through an orientation to others. On the other hand, comfort was not significantly related to excessive external adaptation and rejection–avoidance need. These results suggest a difference in the nature of two aspects of Ibasho: role sense and comfort. The sense of role was a concept that depended on external criteria and was predicted by orientation to others, which is excessive external adaptation. Based on these results, we recommend adaptive Ibasho.
