This study reports on 82 unduplicated cases of violence against women and children after the Great East Japan Disaster of March 2011. Data were collected using a structured questionnaire from informants who worked with the disaster-affected populations. In addition to domestic violence, reported cases involved sexual assault and unwanted sexual contact, including quid pro quo assault perpetrated by nonintimates. Perpetrators often exploited a sense of fear, helplessness, and powerlessness and used threats to force compliance with sexual demands in exchange for life-sustaining resources. Findings point to the urgent need to develop measures to prevent and respond to postdisaster gender-based violence.
