The purpose of this study was to develop Japanese version of the Adolescent Time Attitude Scale (ATAS-J). The ATAS was originally developed by Worrell et al. (2013) and consists of six subscales assessing two valences (positive and negative) with each three time periods (past, present, and future). This scale have been translated and used in various countries. In this study, the ATAS was translated into Japanese, and the reliability and validity of ATAS-J was confirmed in samples of Japanese high school students aged 15-18 years old. Internal consistency estimates for scores on the ATAS-J were over .70. To examine structural validity, four models were compared by confirmative factor analysis. Results indicated that a 6 factor model yielded the best fit for score. With comparing previous study, Japanese adolescents seemed to look more negatively to present and future.
