Tokyo subways are attacked with sarin gas
Several packages of deadly sarin gas are set off in the Tokyo subway system killing twelve people and injuring over 5,000 on March 20, 1995. Sarin gas was invented by the Nazis and is one of the most lethal nerve gases known to man. Tokyo police quickly learned who had planted the chemical weapons and began tracking the terrorists down. Thousands of checkpoints were set up across the nation in the massive dragnet.
The gas attack was instituted by the Aum Shinrikyo (which means Supreme Truth) cult. The Supreme Truth had thousands of followers all over Japan who believed in their doomsday prophecies. Because it claimed the personal assets of new cult members, the Supreme Truth had well over a billion dollars stashed away. Shoko Asahara, a forty-year-old blind man, was the leader of the cult. Asahara had long hair and a long beard, wore bright robes, and often meditated while sitting on satin pillows. His books included claims that he was the second coming of Jesus Christ and that he had the ability to travel through time.

Japanese authorities raided the Supreme Truth compounds across the country, but could not find Asahara. At one camp at the base of Mt. Fuji, police found tons of the chemicals used to produce sarin gas. They also found plans to buy nuclear weapons from the Russians. The police eventually located Hideo Murai, one of the cult’s other top leaders, but when he was being taken into custody he was stabbed to death by an assassin who blamed Murai for the poison gas attack.
Shortly after, the police found a hidden basement at the Mt. Fuji compound where other cult leaders were holed up, including Masami Tsuchiya, a chemist who admitted making the sarin gas. Still, Asahara remained at large and the Supreme Truth made four more gas attacks on the subways, injuring hundreds more. Another potential deadly chemical bomb was defused in a subway restroom.The nation’s top police officer was shot by a masked terrorist, adding to the country’s unrest.
Finally on May 16, Asahara was found in yet another secret room of the Mt. Fuji compound and arrested. Along with scores of the other Supreme Truth leaders, Asahara was charged with murder. Their doomsday predictions had finally come true, albeit on a much smaller and more personal scale than they had envisioned.
