The construction process of a Japanese version of the MPI was described. An attempt was made to construct a test which was adequate for Japanese populations on the basis of item analysis and factor analysis. Normative data were reported concerning the Japanese version of the MPI. The test was found to have a satisfactory reliability. Correlations between 2 MPI scales and some Japanese representative inventories showed high validities of these scales. The extraversion scale was found to be independent of the neuroticism scale and lie scale. On a group of college students a Japanese translation of the EPI was compared with the Japanese version of the MPI and high correlations between corresponding scales were found.
