Aum Shinrikyo was a Japanese new religious movement and apocalyptic cult founded by Shoko Asahara in 1987. It became internationally notorious for the 1995 Tokyo subway sarin attack and other violent crimes, and later split into successor groups including Aleph and Hikari no Wa.

Origins and beliefs

Aum Shinrikyo began as a spiritual movement in Japan in the 1980s and adopted an apocalyptic worldview. It was founded by Shoko Asahara, also known as Chizuo Matsumoto. The group's beliefs combined elements of Buddhism, Hinduism, and Christianity, with an emphasis on millenarian and apocalyptic themes.

Violent crimes and attacks

Aum Shinrikyo carried out the 1995 Tokyo subway sarin attack, which killed 13 people and injured thousands. It was also linked to the 1994 Matsumoto sarin attack and other violent crimes. These attacks made the group one of the most notorious modern examples of religiously framed terrorism.

After the Tokyo subway attack, Japanese authorities cracked down on the organization and prosecuted its leaders. The original group lost its official religious status in Japan, and later legal successor groups such as Aleph and Hikari no Wa appeared.

Successor groups

After Aum Shinrikyo's collapse, its members reorganized into groups such as Aleph and Hikari no Wa. These groups have sought to distance themselves from the violence associated with Asahara's leadership. The original organization was dismantled, but successor groups continued to exist in Japan.
