The trial of Shinzo Abe's killer has highlighted the influence of an Asian mega-church

The man who assassinated former Japanese Prime Minister Shinzo Abe in 2022 was sentenced to life in prison on Wednesday.

Tetsuya Yamagami, 45, was arrested at the scene of the crime in Nara, where the veteran politician and Japan's longest-serving prime minister had been campaigning for his Liberal Democratic Party (LDP). Yamagami admitted to the killing in court last October.

The trial at the Nara District Court underscored ties between the LDP and the Unification Church, a powerful South Korean-based religious group founded in 1954 by self-proclaimed messiah Sun Myung Moon, which critics label a money-making cult.

Media reports said Yamagami testified he held a grudge against the church, colloquially called the Moonies, after his mother donated the family's savings to it. The defendant said he targeted Abe because the former prime minister had supported an event organized by a group linked to the church.

An internal LDP investigation found more than a hundred lawmakers had connections to the Unification Church. Historically, the conservative Japanese party and the church shared common ground in opposing communism and other left-wing ideologies.

After Abe's assassination, then-Prime Minister Fumio Kishida was forced to publicly distance the LDP from the church. Last March, the Tokyo District Court ordered the dissolution of the organization's Japanese branch.

While Abe is considered a divisive figure domestically, many foreign leaders credited him for skilled diplomacy and an ability to forge good personal connections. Russian President Vladimir Putin hosted Abe's widow Akie at the Kremlin last May.
