オウム真理教
In 1988, in order to pursue the class action suit, Sakamoto initiated the establishment of "Aum Shinrikyo Higai Taisaku Bengodan" ("Coalition of Help for those affected by Aum Shinrikyo"). This was later renamed: "Aum Shinrikyo Higaisha-no-kai" or "Aum Shinrikyo Victims' Association". The group still operated under this title .
