Editing Tetsuya Yamagami (section)

=== Before assassination ===
Yamagami's mother had become infatuated with the [[Wikipedia:en:Unification Church|Unification Church]] in the 1991 after the suicide of her husband in the 1984, and by 1998 had made dozens of large donations to the church. In addition to the funds, this donation also included land formerly owned by her father. As a result, the Yamagami family went bankrupt in 2002, and Yamagami, thinking that the church was responsible for this, planned to take revenge against the church. At first, he planned to assassinate a senior church official, but later decided it was impossible, and switched his target to members of the [[Wikipedia:en:Liberal Democratic Party (Japan)|Liberal Democratic Party]] (LDP) with the church as its base support. Although Abe was not a member of the church, he had some contact with the church through the UPF, an organization friendly to the church. Yamagami took notice of this and determined that Abe was a member of the Church. He switched the target of the assassination to Abe.

Yamagami had initially planned to kill using small dynamite, but after experimentation found it impossible because it could involve others the explosion, and the weapons used were switched to firearms. In spring 2020, he had already created some guns based on a video posted on YouTube about how to make guns. Also, the day before the incident, a surveillance camera in Nara with recording recorded what sounded like explosions late at night.
