There is a pressing need for more evidence from regions from Western countries to draw conclusive outcomes concerning psychological sciences. Hence, the study intends to develop the Japanese version of the short form of the Five-Factor Narcissism Inventory; (FFNI-SF) to assess reliability and validity, and to explore the psychometric adaptation of a broad range of narcissistic personalities in relation to the Japanese people. Altogether, 449 Japanese undergraduate students took part in this study. The findings denoted that FFNI-SF had an acceptable level of reliability and correlated well with existing Japanese scales. Based on the exploratory factor analysis, the lack of empathy was excluded from grandiosity, yielding an isolated factor. However, the exploratory factor analysis revealed that the lack of empathy had nothing to do with Japanese narcissism.
