The Tokyo subway sarin attack (地下鉄サリン事件, Chikatetsu Sarin Jiken, "Subway Sarin Incident") was an act of domestic terrorism perpetrated on 20 March 1995, in Tokyo, Japan, by members of the cult movement Aum Shinrikyo. In five coordinated attacks, the perpetrators released sarin on three lines of the Tokyo Metro (then Teito Rapid Transit Authority) during rush hour, killing 13 people,[1][2][3][4][5] severely injuring 50 (some of whom later died), and causing temporary vision problems for nearly 1,000 others. The attack was directed against trains passing through Kasumigaseki and Nagatachō,[6] where the National Diet (Japanese parliament) is headquartered in Tokyo.[7]
