This study examined the circumplex structure of Japanese interpersonal trait words based on a psycho-lexical approach. Seven hundred and nineteen undergraduate students rated 259 interpersonal trait words in regard to how accurately these words described their personality; the data were analyzed using principal component analysis. The trait words were plotted on a two-dimensional space according to their conceptual similarity, which showed a circumplex structure with two orthogonal axes—Dominance and Affiliation—suggesting the cross-cultural validity of the circumplex structure of the interpersonal trait words. Extraversion trait words were located at almost the same position as in previous studies using languages other than Japanese. Agreeable trait words were located near the Affiliation axis, which requires further research. In conclusion, trait words may be useful for constructing an item pool of interpersonal traits in Japan.
