The Tokyo subway sarin attack (Subway Sarin Incident (地下鉄サリン事件 Chikatetsu Sarin Jiken)), was an act of domestic terrorism perpetrated on March 20, 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 present-day Tokyo Metro (then part of the Tokyo subway) during rush hour, killing 12 people, severely injuring 50 and causing temporary vision problems for nearly 5,000 others. The attack was directed against trains passing through Kasumigaseki and Nagatachō, home to the Japanese government.
