is a Zainichi Korean member of , an (impersonated-)uyoku organization, and the Mie Prefecture-based Hane-gumi branch of Yamaguchi-gumi, a Yakuza organization. Jo assassinated Hideo Murai, a member of Aum Shinrikyo, on April 23, 1995. Charges that Kenji Kamimine (上峯憲司), a former leader of Hane-gumi, ordered Jo to kill Murai were dismissed by the Tokyo High Court. Jo had claimed Kenji had ordered him to kill any Aum Shinrikyo leaders that he could. It is believed that this was done out of fear of the Yakuza's connections to the cult being made public. Jo was sentenced to 12 years in prison for the murder.
