Early Life and Childhood
Tetsuya Yamagami was born in Mie Prefecture, Japan, in 1980. His family initially lived a comfortable life. His father was an engineer and ran a construction business, which provided financial stability. However, tragedy struck early. In 1984, when Yamagami was just four years old, his father died by suicide. This left the family shaken and vulnerable.
His mother soon became deeply involved with the Unification Church, a religious group founded in South Korea. She donated huge amounts of money to the church, eventually bankrupting the family. This devotion to religion meant that Yamagami and his siblings often lacked basic support. The family’s financial ruin created a lasting impact on him, shaping his anger and resentment.
Education Journey
Yamagami attended Nara Prefectural Koriyama Senior High School. He was intelligent but struggled with personal issues at home. His dream was to become a firefighter, but poor eyesight prevented him from pursuing that career. This was another disappointment in a life already filled with setbacks.
After high school, he tried to continue his studies. His uncle, a lawyer named Tōichirō Yamagami, supported him financially because his mother had given away most of the family’s money to the church. Despite this help, Yamagami’s education was unstable. He enrolled in vocational courses but often had to pause due to financial and emotional difficulties. His mother’s donations to the Unification Church continued to affect his life.
Family Background
Yamagami’s family story is central to understanding his actions. His father’s suicide left the family without a strong figure of support. His mother’s devotion to the Unification Church consumed much of the family’s wealth. Reports suggest she donated more than 100 million yen, leaving the family bankrupt.
His brother faced serious health problems, including lymphoma. Sadly, he died by suicide in 2015, adding another layer of tragedy to the family’s history. Yamagami also had a sister, though little is publicly known about her. His uncle, Tōichirō, played an important role in his life, helping him financially and later serving as an advisor during his trial.
Military Career
After finishing high school and struggling with his education, Tetsuya Yamagami decided to join the Japan Maritime Self-Defense Force (JMSDF) in 2002. He served for about three years, until 2005. His rank was Leading Seaman, which is a junior enlisted position. During this time, he received basic training in handling weapons and military discipline.
Reports suggest that Yamagami attempted suicide during his service because of the heavy burden he carried from his family’s financial problems. His mother’s donations to the Unification Church had left the family bankrupt, and he felt responsible for supporting his siblings. This emotional weight made it difficult for him to focus on his duties.

Career After Military Service
After leaving the Self-Defense Force, Yamagami tried to live a normal life. He worked in more than ten different companies over the next 17 years. His jobs included surveying, forklift operation, and temporary staffing. However, he never stayed long in one place. He often resigned or was dismissed because of personal issues, health problems, or dissatisfaction.
This unstable career path reflected his inner struggles. He was intelligent and capable, but his anger toward the Unification Church and his family’s financial ruin kept him from building a stable future. He lived in small apartments and often moved from one job to another. His colleagues described him as quiet and reserved, someone who did not share much about his personal life.
Connection with the Unification Church
The Unification Church played a central role in Yamagami’s life story. His mother became a devoted follower after his father’s death. She donated more than 100 million yen to the church, which eventually led to the family’s bankruptcy in 2002. This left Yamagami and his siblings without financial support.
Yamagami believed that the church had destroyed his family. He saw his mother’s devotion as blind faith that ignored the needs of her children. His brother’s illness and later suicide in 2015 added to his anger. He felt that the church had taken away not only money but also the stability and happiness of his family.
Assassination of Shinzo Abe (2022)
On July 8, 2022, Yamagami carried out the act that made him infamous. Abe was giving a campaign speech in Nara, a city in western Japan. Yamagami approached the crowd with a homemade shotgun. He fired two shots, and Abe collapsed. Despite efforts to save him, Abe died later that day.
The weapon Yamagami used was built from metal pipes and parts he purchased online. He had tested similar weapons in advance to make sure they worked. His ability to build such a gun came from his military training and his careful study of online resources.
Criminal Proceedings and Trial
After his arrest in July 2022, Tetsuya Yamagami was charged with multiple crimes, including murder, illegal weapon manufacturing, explosives control violations, and property damage. His case quickly became one of the most closely watched trials in Japan. Authorities ordered a psychiatric evaluation to determine whether he was mentally fit to stand trial. This evaluation lasted for months, reflecting the seriousness of the case.
In October 2025, his trial officially began. The courtroom was filled with media, legal experts, and members of the public who wanted to witness the proceedings. Prosecutors argued that Yamagami had carefully planned the assassination, building weapons and testing them in advance. They emphasized that his actions were deliberate and calculated. On January 21, 2026, the court sentenced him to life imprisonment.
