Japan | From Ruin to Retribution: Unpacking the Motive Behind Abe's Assassination

Tetsuya Yamagami
Tetsuya Yamagami, the 45-year-old man who assassinated former Japanese Prime Minister Shinzo Abe on July 8, 2022, has consistently stated that his motive was rooted in deep-seated resentment toward the Unification Church (now known as the Family Federation for World Peace and Unification, often called the "Moonies"). 

He blamed the church for destroying his family through coercive financial donations and emotional manipulation, and he targeted Abe as a prominent political figure he viewed as a key enabler of the church's influence in Japan due to longstanding ties with the ruling Liberal Democratic Party (LDP). 

Yamagami has described his act not as political assassination but as a desperate response to personal ruin, telling investigators, "I had no choice but to choose Mr. Abe as a murder target." 


Yamagami was born in 1980 in Nara Prefecture into a relatively affluent family; his father was a construction company executive, and his mother, Ako, came from wealth.

His maternal grandmother died in a car accident when he was 1, shattering his mother's mental health. At age 4, his father died by suicide, leaving Ako to raise Yamagami and his two siblings alone. Around the same time, his older brother (one year his senior) was diagnosed with childhood brain cancer, losing sight in one eye after grueling treatments.

Devotion's Cost: Donations and Downfall


Vulnerable and grieving, Ako joined the Unification Church around 1991 after a recruiter offered a "prayer healer" to exorcise "ancestral evil spirits"—a common tactic targeting bereaved families. 

 She believed the church's teachings, which blend Christian elements with Korean nationalism and claims of resolving spiritual debts from Japan's colonial history, "saved" her. 

 Ako became deeply devoted, attending events in South Korea, volunteering extensively, and donating over 100 million yen (approximately $660,000–$700,000) from her late husband's life insurance, family assets, and inheritance.

This included funds earmarked for the children's education, leading to the family's bankruptcy by the mid-1990s amid Japan's economic downturn. 

The home became chaotic with empty fridges and piled dishes, forcing the kids to beg neighbors for food. Yamagami, then a teenager, learned of the donations around age 14, later writing on Twitter (now X) in 2020 that this was when "my family fell apart." 

Family tensions escalated; his grandfather once attacked Ako with a knife in frustration, and his older brother clashed violently with her over the church. 

Yamagami tried to mediate, studying church doctrine to empathize with his mother but never converting. 

In 2015, his brother died by suicide amid ongoing poverty and illness, an event that deepened Yamagami's rage; he broke down at the funeral, partly blaming his mother. 

Yamagami's grievances focused on the church's exploitative practices, which he said coerced his mother into ruinous donations via guilt over "ancestral purgatory" and overpriced spiritual items. 

This left him and his siblings in poverty, forcing him to abandon university dreams despite attending a top high school. He joined Japan's Maritime Self-Defense Force in 2002 to escape but attempted suicide in 2005, attempting to secure life insurance for his siblings.

A Life of Isolation and Online Outcries


 Years of menial jobs, isolation, and despair followed—no marriage, no children, and a sense of a "distorted" life, as he posted on Twitter from 2019–2021 to a tiny audience. 

He vowed never to forgive the church or its "Japanese allies," viewing it as the root of his father's and brother's suicides, family fractures, and lifelong hardship. 

Initially, Yamagami tried supporting his mother but grew suffocated by her prioritization of the church, mixing resentment with lingering love and unfulfilled hope for her "awakening." 

Post-2015, his anger became "uncontainable," evolving into a plan for revenge: He built homemade guns and even fired at a local church building days before the assassination to signal his intent.

Pivot to a Political Target


Shinzo Abe
Yamagami shifted from targeting church leaders (like Hak-ja Han, whom he couldn't access in 2019) to Abe after seeing a 2021 video of the former PM praising a church-affiliated group, the Universal Peace Federation. 

He viewed Abe as the most influential "sympathizer" in a corrupt LDP-church alliance dating to Abe's grandfather, Nobusuke Kishi, who protected the group in the 1960s for anti-communist organizing and campaign volunteers. 

To Yamagami, Abe symbolized a "blood-soaked lineage" shielding the church's abuses, allowing it to extract billions from Japanese families like his to fund overseas operations. 

Yamagami pleaded guilty on October 28, 2025, at Nara District Court, expressing remorse but reiterating his church-driven motive; prosecutors seek the death penalty, with a verdict expected January 21, 2026. 

The trial has exposed "religious abuse" and LDP ties, with his mother testifying as a defense witness—she remains a member but has apologized in prison letters, feeling parental responsibility. 

This comes amid broader fallout: A March 2025 court ordered the church's dissolution (under appeal), and surveys show over 70% of Japanese view it negatively. 

A Symbolic Tribute to Abe


PM Takaichi gifts President Donald Trump a golf bag signed by Hideki Matsuyama and Prime Minister Abe’s putter.
Japanese Prime Minister Sanae Takaichi presented President Donald Trump with a putter once used by the late Shinzo Abe during their first meeting in Tokyo on Oct. 27, invoking the assassinated leader's close friendship with the U.S. president to strengthen bilateral ties. 

The symbolic gift, displayed in a glass case, was part of a suite of golf-themed presents, including a gold leaf-decorated golf ball and tee set, and a bag autographed by Japanese pro golfer Hideki Matsuyama. 

Abe, who served as Japan's prime minister for nearly eight years until his 2022 assassination, frequently golfed with Trump during his presidency, forging a personal bond that Takaichi referenced to rekindle alliances amid global uncertainties.

Takaichi, who assumed office last month, aims to build on Abe's "Abenomics" policies and security initiatives while navigating Trump's tariff threats and demands for defense spending increases.

The exchange highlighted golf's role in diplomacy, with world leaders increasingly turning to the sport to woo the golf-enthusiast president.

Will the US Supreme Court end nitrogen gas executions?

When President Donald Trump returned to office in January 2025, he directed his administration to “ restor[e] the death penalty .” His embrace of capital punishment helped fuel a surge in executions at the state level last year, as I previously reported , and led the Justice Department to produce a report on “strengthening” the federal death penalty, which was released late last month. In the report, the Justice Department defended the use of pentobarbital – a powerful sedative – for lethal injections, criticizing the Biden administration’s determination that it may cause “unnecessary pain and suffering.” Nevertheless, citing ongoing legal challenges to pentobarbital use and related problems obtaining the drugs used in lethal injections, the DOJ recommended expanding the list of federal execution methods by adding firing squads, electrocution, and lethal gas.

20 Minutes to Death: Witness to the Last Execution in France

The following document is a firsthand account of the final moments of Hamida Djandoubi, a convicted murderer executed by guillotine at Marseille’s Baumettes Prison on September 10, 1977. The record—dated September 9—was written by Monique Mabelly, a judge appointed by the state to witness the proceedings. Djandoubi’s execution would ultimately be the last carried out in France before capital punishment was abolished in 1981. At the time, President Valéry Giscard d'Estaing—who had publicly voiced his "deep aversion to the death penalty" prior to his election—rejected Djandoubi’s appeal for clemency. Choosing to let "justice take its course," the President allowed the execution to proceed, just as he had in two previous cases during his term:   Christian Ranucci , executed on July 28, 1976 and Jérôme Carrein , executed on June 23, 1977. Hamida Djandoubi , a Tunisian national, was sentenced to death for killing his former lover, Elisabeth Bousquet. He was execu...

South Dakota | Latest appeal from state's lone death row inmate denied

SIOUX FALLS, S.D. (KELO) — The U.S. Court of Appeals for the 8th Circuit has rejected the latest appeal from Briley Piper, the only person on death row in South Dakota. In March 2000, Briley Piper, along with co-defendants Elijah Page and Darrell Hoadley, conspired to burglarize the Lawrence County home of 19-year-old Chester Poage before abducting and murdering him by beating, stabbing, and stoning in a remote area.  Piper was subsequently arrested, convicted of murder, and sentenced to death, while his accomplices received either a death sentence—carried out against Page in 2007—or a sentence of life imprisonment without parole. 

South Carolina | Inmate who believes he’s died repeatedly can’t be executed, judge rules

SPARTANBURG — A 59-year-old man sentenced to death for killing a state trooper in Greenville County in 2000 can’t be executed because of a mental illness that’s left him incoherent and believing he’s immortal, a Circuit Court judge has ruled. John Richard Wood is the first condemned inmate in South Carolina found not competent to be executed since the state restarted capital punishment in September 2024. The seven executions since then include three men who chose to die by firing squad — the latest in November. Wood, convicted 24 years ago, was among death row inmates in line to receive a death warrant after exhausting their regular appeals.

American Fugitive Flees to Italy hoping to Escape the Death Penalty

American Murder Suspect Cut Off His Ankle Bracelet and Fled to Italy to Escape the Death Penalty Lee Mongerson Gilley Flew From Houston to Milan on Two False Identities. He Was Caught the Moment He Landed. It reads like the opening of a thriller. A man under electronic surveillance in Houston, suspected of killing his pregnant wife, cuts off his ankle bracelet, boards a flight to Canada under a false identity, transfers to a second flight to Italy under a second false identity, and lands at Milan Malpensa with a single objective: to place himself beyond the reach of Texas justice and its death penalty. The plan failed at the first step on Italian soil. Lee Mongerson Gilley, 39, an American software engineer wanted in the United States on suspicion of murdering his ex-wife in October 2024, was identified and detained the moment he arrived at Malpensa. He had cut off his electronic monitoring bracelet in Houston, flown first to Canada using one set of false documents, and then to Italy u...

Former FedEx driver sentenced to death for killing 7-year-old girl after delivery at her Texas home

DALLAS (AP) — A former FedEx driver was sentenced to death on Tuesday after he pleaded guilty to killing a 7-year-old girl he took from her Texas home while delivering a Christmas gift. Jurors in a Fort Worth courtroom decided on Tanner Horner's punishment after hearing about a month of testimony and evidence that included audio of Athena Strand's last moments from inside his delivery van. Horner, 34, pleaded guilty to capital murder last month in the 2022 killing just as his trial began. Athena's body was found two days after she was reported missing from her home in the rural town of Paradise, near Fort Worth.

Arizona | Man who murdered pastor crucifixion style requests plea deal after parents killed in plane crash

Adam Sheafe, the California man who admitted to killing a New River, Arizona, pastor in a crucifixion-style attack, has asked prosecutors to offer him a plea deal that would result in a natural life sentence rather than the death penalty he had previously sought. Advisory council attorneys representing Sheafe sent a formal plea offer to prosecutors this week, about two weeks after his father and stepmother died in a plane crash at Marana Airport on April 8, according to 12 News. Sheafe, 51, is charged with first-degree murder in the death of William Schonemann, 76, pastor of New River Bible Church, who was found dead inside his home last April.

China | Man sentenced to death for murder executed in Yunnan

Tian Yongming, who was initially sentenced for a series of violent crimes and then had his sentence changed to death early this year, has been executed in Yunnan province following approval from China's top court. The execution was carried out by the Intermediate People's Court in Yuxi, Yunnan, on Tuesday, with local prosecutors supervising the process. Before the execution, Tian was allowed to meet with his family members. The case dates back to September 1996, when Tian was sentenced to nine years in prison for the rape and attempted murder of his sister-in-law. After his release on July 15, 2002, he plotted revenge against the woman. On the night of Nov 13, 2002, he broke into her home armed with a knife.

Idaho eyes restart of death row executions as firing squad draws near

BOISE, Idaho — Idaho’s prison system has nearly completed execution chamber upgrades to carry out the death penalty by firing squad as the state’s lead method and will have a team of riflemen ready to go by the time a state law takes effect this summer. As part of the transition, the Idaho Department of Correction hopes to limit participation by its officers as the shooting of condemned people in prison to death is prioritized over lethal injection. Toward that effort, prisoner leadership sought to implement a push-button technology to avoid needing IDOC workers to pull the triggers.
