Aleph (Japanese: アレフ, Hepburn: Arefu), better known by their former name Aum Shinrikyo (オウム真理教, Ōmu Shinrikyō; lit. 'religion of Aum Supreme Truth'), is a Japanese new religious movement and doomsday cult founded by Shoko Asahara in 1987. It carried out the deadly Tokyo subway sarin attack in 1995 and was then found to have been responsible for the Matsumoto sarin attack the previous year.
The group says that those who carried out the attacks did so secretly, without their plans being known to other executives and ordinary believers. Asahara insisted on his innocence in a radio broadcast relayed from Russia and directed toward Japan.
On 6 July 2018, after exhausting all appeals, Asahara and six followers on death row were executed as punishment for the 1995 attacks and other crimes. Six additional followers were executed on 26 July. At 12:10 AM, on New Year's Day 2019, at least nine people were injured (one seriously) when a car was deliberately driven into crowds celebrating the new year on Takeshita Street in Tokyo. Local police reported the arrest of Kazuhiro Kusakabe, the suspected driver, who allegedly admitted to intentionally ramming his vehicle into crowds to protest his opposition to the death penalty, specifically in retaliation for the execution of the aforementioned Aum cult members.
Aum Shinrikyo, which split into Aleph and Hikari no Wa in 2007, had already been formally designated a terrorist organization by several countries, including Russia, Canada, Japan, France, Kazakhstan, and the European Union. It was previously designated by the United States as a terrorist organization until 2022, when the State Department determined the group to be largely defunct.
The Public Security Intelligence Agency considered Aleph and Hikari no Wa to be branches of a "dangerous religion" and it announced in January 2015 that they would remain under surveillance for three more years. The Tokyo District Court canceled the extension to surveillance of Hikari no Wa in 2017 following legal challenges from the group, but continued to keep Aleph under watch. The government appealed the cancellation, and in February 2019, the Tokyo High Court overturned the lower court's decision, reinstating the surveillance, citing no major changes between Aum Shinrikyo and Hikari no Wa.
The movement "evolved out of a yoga school founded by Asahara Shoko in the Shibuya district of Tokyo in February 1984". The movement was known as Ōmu Shinsen no Kai (オウム神仙の会, "Aum Heavenly Sage Association") and steadily grew in the following years. Its original teachings were based on doctrines derived from Nichiren-based sects such as Nichiren Shōshū and Soka Gakkai. They gained official status as a religious organization in 1989 and attracted a considerable number of graduates from Japan's elite universities, thus being dubbed a "religion for the elite".
Aum was controversial in Japan from the start but wasn’t linked to serious crimes at first. It was during this period that Asahara became obsessed with Biblical prophecies. Aum's public relations activities included publishing comics and animated cartoons that attempted to tie its religious ideas to popular anime and manga themes, including space missions, powerful weapons, world conspiracies, and the quest for ultimate truth. Aum published several magazines including Vajrayana Sacca and Enjoy Happiness, adopting a somewhat missionary attitude.
Isaac Asimov's science fiction Foundation Trilogy was referenced "depicting as it does an elite group of spiritually evolved scientists forced to go underground during an age of barbarism to prepare themselves for the moment...when they will emerge to rebuild civilization". Lifton posited that Aum's publications used Christian and Buddhist ideas to impress what he considered to be the more shrewd and educated Japanese who were not attracted to boring, purely traditional sermons.
Advertising and recruitment activities, dubbed the "Aum Salvation plan", included claims of curing physical illnesses with health improvement techniques, realizing life goals by improving intelligence and positive thinking, and concentrating on what was important at the expense of leisure. This was to be accomplished by practicing ancient teachings, accurately translated from original Pali suttas (these three were referred to as "threefold salvation"). These efforts resulted in Aum becoming one of the fastest-growing religious groups in Japan's history.
David E. Kaplan and Andrew Marshall claim that its practices remained secret. Initiation rituals often involved the use of hallucinogens, such as LSD. Religious practices often involved extremely ascetic practices claimed to be "yoga". These included everything from renunciants being hung upside down to being given shock therapy.
In the early days, Aum was able to recruit a variety of people ranging from bureaucrats to personnel from the Japanese Self-Defense Forces and the Tokyo Metropolitan Police.
The cult started attracting controversy in the late 1980s with accusations of deception of recruits, holding cult members against their will, forcing members to donate money, and murdering a cult member who tried to leave in February 1989.
In October 1989, the group's negotiations with Tsutsumi Sakamoto, an anti-cult lawyer threatening a lawsuit against them, which could potentially bankrupt the group, failed. In the same month, Sakamoto recorded an interview for a talk show on the Japanese TV station TBS. The network then had the interview secretly shown to the group without notifying Sakamoto, intentionally breaking protection of sources. The group then pressured TBS to cancel the broadcast. The following month, Sakamoto, his wife and his child went missing from their home in Yokohama. The police were unable to resolve the case at the time, although some of his colleagues publicly voiced their suspicions of the group. It was not until after the 1995 Tokyo attack that they were found to have been murdered and their bodies dumped in separate locations by cult members.
Kaplan and Marshall allege in their book that Aum was also connected with such activities as extortion. The group, authors report, "commonly took patients into its hospitals and then forced them to pay exorbitant medical bills".
The cult is known to have considered assassinations of several individuals critical of the cult, such as the heads of Buddhist sects Soka Gakkai and The Institute for Research in Human Happiness. After manga artist Yoshinori Kobayashi began satirizing the cult, he was included on Aum's assassination list. An assassination attempt was made on Kobayashi in 1993.
In 1991, Aum began to use wiretapping to get NTT uniforms/equipment and created a manual for wiretapping.
In July 1993, cult members sprayed large amounts of liquid containing Bacillus anthracis spores from a cooling tower on the roof of Aum Shinrikyo's Tokyo headquarters. However, their plan to cause an anthrax epidemic failed, likely because they used a vaccine strain of Bacillus anthracis that is generally regarded as nonpathogenic. The attack resulted in a large number of complaints about bad odors but no infections.
At the end of 1993, the cult started secretly manufacturing the nerve agent sarin and, later, VX. Aum tested its sarin on sheep at Banjawarn Station, a remote pastoral property in Western Australia, killing 29 sheep.
