Abstract
This paper reviews the studies on personality in Japanese psychological research. The trends in personality research during the last year are reviewed, and the following problems, which should be investigated, are presented. First, almost all studies are using scales or are developing scales, and there are few theoretical studies that examine personality concepts or offer frameworks for understanding personality. This research gap needs to be addressed. Second, clarifying the features of each scale and organizing them becomes necessary as many scales are similar. Third, it is necessary to present the reasons for using a specific scale to prevent their random use. Fourth, many personality concepts are proposed based on factor analysis, and the differences between each concept are not examined theoretically. Finally, statistical significance is overestimated, so developing a guideline that gives meaning to the obtained data is a must.
