Aleph (Japanese: アレフ, Hepburn: Arefu), formerly Aum Shinrikyo (オウム真理教, Oumu Shinrikyō, literally 'Supreme Truth'), is a Japanese doomsday cult and terrorist organization founded by Shoko Asahara in 1984. It carried out the deadly Tokyo subway sarin attack in 1995 and was found to have been responsible for the Matsumoto sarin attack the previous year. The group says that those who carried out attacks did so secretly, without being known to other executives and ordinary believers. Asahara insisted on his innocence in a radio broadcast relayed from Russia and directed toward Japan.
