In this study, participants (623 students) were examined using two scenarios whether justifiability evaluation of anger expression would be affected by the differences in victim's position or perpetrator's position, the magnitude of damage, and perpetrator's responsibility. As a result, against the prediction, perpetrators tended to evaluate victim's anger expression as being more justifiable than victims. However, since the magnitude of damage and responsibility had significant influences on justifiability evaluation, and these influences were stronger in perpetrators than in victims, the other hypotheses were supported. Moreover, in the specific situation, it was suggested that expressing anger was evaluated as being more justifiable than suppressing anger.
