The former Taiwanese comfort women were forced to go to the battlefield and sexually abused by the Japanese government during the World War II. This extraordinary sexual abuse experience they suffered causes both serious lifelong physical and psychological traumas. This research utilized the framework of drama-therapy and the guidance of interpretive and action research approach to study the contents of drama-therapy groups of Taiwanese comfort women through the view of historical background. This article is written based on the historical background research, contents of the group progress, and related literature reviews of this subject. The comfort women are victims of sexual abused under special historical situation. The authors will focus on the understanding process of trauma recovery in the literature review. Since the problems of comfort women are extensively complicated, this study will focus on the psychotherapy in the late years of life of these comfort women. The drama therapy groups used drama ceremony to create a space for them to express their feelings. The group process is divided into four stages, includes warm-up stage, main activity stage I: the experience with Japanese, main activity stage II: self-dialogue, and final activity stage: symbolized treatment ceremony. In the scenes of drama groups, they can forgive themselves through self-dialogue to their younger selves. In addition, the participants grief for them self during the drama therapy and then develop the ability to start self-integration which is the first step for their recovery. This argument is supported by the fact that they changed their attitude toward their trauma and past after the group drama-therapy.
