As trial opens, Tetsuya Yamagami admits murdering Japan’s longest serving leader three years ago.

The man accused of killing former Japanese Prime Minister Shinzo Abe in 2022 has pleaded guilty to murder.

Forty-five-year-old Tetsuya Yamagami admitted all charges read out by prosecutors as his trial opened on Tuesday, according to the Japanese broadcaster NHK.

Yamagami was charged with murder and violations of arms control laws for allegedly using a handmade weapon to shoot Japan’s longest serving leader.

“Everything is true,” the suspect told the court, according to the AFP news agency.

Abe was shot as he gave a speech during an election campaign in the western city of Nara on July 8, 2022. Yamagami was arrested at the scene.

The assassination was reportedly triggered by the suspect’s anger over links between Abe’s Liberal Democratic Party (LDP) to the Unification Church.

Yamagami held a grudge against the South Korean religious group due to his mother’s donation of 100 million yen ($663,218). The gift ruined his family’s financial health, Japanese media reported.

Long the subject of controversy and criticism, the Unification Church, whose followers are referred to disparagingly as “Moonies”, has since faced increased pressure from authorities over accusations of bribery.

The church’s Japanese followers are viewed as a key source of income.

The shooting was followed by revelations that more than 100 LDP lawmakers had ties to the Unification Church, driving down public support for the ruling party.

After Tuesday’s initial court session, 17 more hearings are scheduled this year before a verdict is scheduled for January 21.

The trial opened the same day as two of Abe’s former allies, LDP leader and Prime Minister Sanae Takaichi and visiting United States President Donald Trump, held a summit in Tokyo.

Abe, who served as Japan’s prime minister for almost nine years, is regularly mentioned by both during public events.

On Tuesday, Takaichi gave Trump a golf putter owned by Abe and other golf memorabilia during their meeting at the Akasaka Palace.
