Traffic psychological research has shown that driving anger leading to maladjusted driving behavior, e.g., risky or aggressive driving behavior, is a main contributor to traffic accidents. However, it is currently far from clear to what extent driving anger is experienced and expressed in Japan. So far, extensive and detailed studies on this critical issue as well as a cross-cultural comparison are lacking in Japan. Our current study aims to bridge this gap. We examined the reliability and validity of a Japanese version of the Driving Anger Scale (DAS; Deffenbacher et al., 1994). Results revealed a new Japanese culture-specific version of the Driving Anger Scale, i.e., a five factors structure with overall 22 items. Results of the study enlighten the experience of driving anger in Japan as well as additionally cross-culturally compared to other countries. Implications for further research and applied issues, e.g., increasing traffic safety, will be outlined.
