Tokyo subway sarin attack

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.

[10] In August 1989, the group was granted official religious corporation status by the Tokyo Metropolitan Government, giving it privileges such as tax breaks and freedom from governmental oversight.

In the year preceding its recognition by the Tokyo government, a member of the cult – Terayuki Majima – had accidentally drowned during a ritual; his body was cremated, with the remaining bones ground up and scattered over a nearby lake.

[18] Simultaneously, Asahara announced that the coming apocalyptic war could not save people outside of the cult, and that members should attend a three-day seminar in Ishigakijima in order to seek shelter.

[citation needed] After the destruction of the illegal weapon stockpiles, the cult relied on 'mainstream' methods to attract other members – this included frequent television appearances by Asahara, as well as the setting up of the 'Aum Shinrikyo broadcasting' radio station in Russia in April 1992.

However, starting in late 1992, Asahara's mental health deteriorated further – he began to complain of hallucinations and paranoia,[10] and he withdrew from public appearances (except on Aum Shinrikyo Broadcasting), claiming society was preventing him from fulfilling his destiny as Christ.

[19] He outlined a doomsday prophecy, which included a Third World War, and described a final conflict culminating in a nuclear Armageddon, borrowing the term from the Book of Revelation 16:16.

Under the oversight of Endo, the biological weapons division of the cult resumed – this time pursuing not only botulinum toxin, but also anthrax, using improved 200-litre (53 US gal) drum fermenters at their Kameido facility.

[citation needed] In the summer of 1993, Endo attempted a different strategy – by desiccating the slurry, the B. anthracis spores could be spread as a powder, rather than through spraying – this was achieved with a crude hot air dryer.

At the same time, in September 1993, Asahara and 24 other cult members traveled from Tokyo to Perth, Australia, bringing generators, tools, protective equipment (including gas masks and respirators), and chemicals to make sarin.

After repurchasing chemicals confiscated by customs, the group chartered aircraft from Perth to Banjawarn Station, where they searched for uranium deposits to make nuclear weapons and may have tested the efficacy of the synthesized sarin on animals.

[24] Despite the safety features and often state-of-the-art equipment and practices, the operation of the facility was very unsafe – one analyst would later describe the cult as having a "high degree of book learning, but virtually nothing in the way of technical skill.

[citation needed] By December, Tsuchiya had accumulated in total about 3 kilograms (6.6 lb) of sarin – from this, two separate assassination attempts were made on Daisaku Ikeda, leader of Soka Gakkai (a rival Japanese religious movement), in mid-1994.

This evidence was left unacted on, but was leaked to the Yomiuri Shimbun in January 1995, alerting Asahara and the cult, and causing Nakagawa and Endo to begin the process of destroying and/or hiding all nerve agents and biological weapons, which lasted until the end of February.

[citation needed] Fingerprint evidence for an Aum member linked to an earlier kidnapping, in addition to the sarin-contaminated soil samples, caused the police to set a raid date for 22 March.

On the way to Sendagi Station, Niimi purchased newspapers to wrap the sarin packets in—the Japan Communist Party's Akahata and the Sōka Gakkai's Seikyo Shimbun.

[31] As the train approached Ochanomizu Station, Hirose dropped the newspapers to the floor, repeated an Aum mantra and punctured both sarin packets with so much force that he bent the tip of his sharpened umbrella.

When they arrived at the station, Yokoyama put on a wig and fake glasses and boarded the fifth car of the Ikebukuro-bound 07:39 Marunouchi Line train number B801 (02 series set 50).

After purchasing a copy of Hochi Shimbun and wrapping his two sarin packets, Toyoda arrived at Naka-Meguro Station where he boarded the first car of northeast-bound 07:59 Hibiya Line train number B711T (Tobu 20000 series set 11).

Prior to the attack, Hayashi asked to carry a flawed leftover packet in addition to the two others in an apparent bid to allay suspicions and prove his loyalty to the group.

[34] After Sugimoto escorted him to Ueno Station, Hayashi boarded the third car of southwest-bound 07:43 Hibiya Line train number A720S (03 series set 10) and dropped his sarin packets to the floor.

Noticing the large, liquid-soaked package on the floor and assuming it was the culprit, one passenger kicked the sarin packets out of the train and onto Kodenmachō Station's subway platform.

The judge also highlighted his self-righteous motive for his crimes and pronounced the sentencing saying that: Though the defendant knew the deadliness of the nerve gas, he took part without hesitation, believing the attack was an "act of salvation"[41]After the verdict was read, his lawyer said that Kitamura was still under Asahara's spell which made him a victim of the cult as well.

[39] Hayashi's getaway driver was 36-year-old Shigeo Sugimoto, whose lawyers argued he played only a minor role in the attack, but the argument was rejected and he was sentenced to life in prison.

Due to fears that armed cult members might resist the raid, the 1st Airborne Brigade of the Japan Ground Self-Defense Force was stationed nearby to provide support if needed.

The cause of the incident was not immediately understood, and many hospitals received information on diagnosis and treatment only because a professor at Shinshu University's school of medicine happened to see reports on television.

[57] A Christian anti-cult Web site called Apologetic Index quoted the Washington Post article and implied that Melton had spoken in the press conference.

[61] Reader concluded that, "The visit was well-intentioned, and the participants were genuinely concerned about possible violations of civil rights in the wake of the extensive police investigations and detentions of followers."

In 1999, the Diet gave the commission broad powers to monitor and curtail the activities of groups that have been involved in "indiscriminate mass murder" and whose leaders are "holding strong sway over their members", a bill custom-tailored to Aum Shinrikyo.

The Tokyo High Court postponed its decision on the appeal until results were obtained from a court-ordered psychiatric evaluation, which was issued to determine whether Asahara was fit to stand trial.
