Former Japanese prime minister Shinzo Abe (pictured) was shot and killed with an improvised firearm due to resentment against the Unification Church.

Shinzo Abe was a Japanese politician who served as Prime Minister of Japan and President of the Liberal Democratic Party (LDP) from 2006 to 2007 and again from 2012 to 2020. He was the longest-serving prime minister in Japanese history, serving for nearly nine years in total.

On 8 July 2022, Shinzo Abe, a former prime minister of Japan and serving member of the Japanese House of Representatives, was assassinated while speaking at a political event outside Yamato-Saidaiji Station in Nara City, Nara Prefecture. Abe was delivering a campaign speech for a Liberal Democratic Party (LDP) candidate when he was fatally shot by 41-year-old Tetsuya Yamagami with an improvised firearm. Abe was transported via medical helicopter to Nara Medical University Hospital in Kashihara, where he was pronounced dead.

Improvised firearms are firearms manufactured by an entity other than a registered firearms manufacturer or a gunsmith. Improvised firearms are typically constructed by adapting existing materials to the purpose. They range in quality, from crude weapons that are as much a danger to the user as the target, to high-quality arms produced by cottage industries using salvaged and repurposed materials.

The Unification Church is a new religious movement, whose members are called Unificationists or sometimes informally Moonies. It was founded in 1954 by Sun Myung Moon in Seoul, South Korea, as the Holy Spirit Association for the Unification of World Christianity ; in 1994, the organization changed its name to the Family Federation for World Peace and Unification. It has a presence in approximately 100 countries around the world. Its leaders are Moon and his wife, Hak Ja Han, whom their followers honor with the title "True Parents".
