The founder of Agon Shū is
Seiyū Kiriyama (birth name, Masuo Tsutsumi) born in 1921 in
Yokohama. His poor health prevented him from serving in the army, and he survived through several odd jobs. In 1953, he was accused of producing alcohol illegally and arrested. He prepared to commit suicide in jail but changed his mind at the last minute. Later, he attributed this to an intervention of the
bodhisattva of compassion
Juntei-Kannon, who entrusted him with a religious mission. He developed friendly relations with the
Jōdo Shinshū Yōgen-in temple in Kyoto, and established the headquarters of its society near the temple. In 1978, Kiriyama announced the "discovery" that the Agamas are the keys to Buddha's teachings, and that Buddhist groups that do not recognize this mislead their followers. In 1980, Kiriyama visited the holy Buddhist site of
Sahet Mahet in
India and reported that the Buddha had appeared to him and passed to him the mantle of leader of universal Buddhism. These events led Kiriyama to establish and promote Agon Shū, founded in 1978, as a new global Buddhist movement and build a "new Sahel Mahet" in
Yamashina-ku, Kyoto. In 1995, the
Tokyo subway sarin attack perpetrated by
Aum Shinrikyo led to a hostile attitude in Japan towards new religious movements in general, and particularly affected Agon Shū when it became known that Aum Shinrikyo's founder,
Shoko Asahara, had been for a short time a member of Kiriyama's movement. Scholars, Ian Reader and Erica Baffelli, suggested that to dissociate himself from Asahara, Kiriyama in his later years emphasized Japanese nationalism and devoted several rituals to pacify the souls of Japanese soldiers who died during
World War II. ==After Kiriyama's death==
