Tetsuya Yamagami is a former member of the Japan Maritime Self-Defense Force. He is known for the assassination of Shinzo Abe, a former prime minister of Japan. This event took place on July 8, 2022, in the city of Nara. Yamagami was arrested at the scene of the crime. At the time of his arrest, he was 41 years old. He had no prior criminal history and was unemployed. His actions led to a major legal and political event in Japan.

Yamagami's early life was shaped by significant family changes. He was born on September 10, 1980, in Mie Prefecture. His parents ran a successful local construction business. However, his family faced many hardships starting in 1991. His mother joined a religious group called the Unification Church. She began making very large monetary donations to the organization. These donations were intended to bring salvation to her family. This included her husband and her eldest son.

The financial impact of these donations was massive. Yamagami's mother donated more than 100 million yen over many years. She used her late husband's life insurance to fund a 20 million yen donation. She also sold the family home for about 40 million yen in 1996. These choices eventually led to her declaring bankruptcy in 2002. This happened when Yamagami was 21 years old. The loss of wealth and stability deeply affected the family members.

Personal tragedies also shaped Yamagami's development. His father died by suicide in 1984 when Yamagami was four. His older brother suffered from a disease called lymphoma. Because of the family's financial situation, the brother could not afford medical treatment. The brother also died by suicide in 2015. Yamagami's uncle, Tōichirō, noted that these losses had a great impact. Yamagami's defense team stated he lived only to see his brother pass away.

Yamagami's career included a period of military service. He joined the Japan Maritime Self-Defense Force in August 2002. He was assigned to the destroyer Abe at the Kure Naval Base. During his service, he experienced deep personal distress. In 2005, he attempted suicide to provide insurance money for his siblings. He stated that the Unification Church had ruined his life. He was discharged from the navy in August 2005 as a leading seaman.

After leaving the military, Yamagami had a difficult professional life. He worked for at least 10 different companies over 17 years. Most of these were short-term part-time jobs or temporary labor. He often left jobs after only about six months. In 2020, he worked as a forklift operator in Kyoto Prefecture. He quit that job in May 2022 because he felt unwell. He then worked briefly for a staffing firm in Osaka before the assassination.

The assassination occurred at 11:30 am near Yamato-Saidaiji Station. Shinzo Abe was delivering a campaign speech for a political candidate. Yamagami approached Abe from behind using a homemade shotgun. He fired two rounds, and Mr. Abe collapsed from his injuries. Bodyguards immediately restrained Yamagami at the scene. He was arrested by the Nara Prefectural Police. He was described as being calm during the arrest.

The legal process following the event was very long. Yamagami underwent a psychiatric evaluation to check his mental competence. This assessment lasted nearly half a year, which is unusual in Japan. He faced four different criminal charges. These included murder and violations of firearm laws. His trial began in Nara on October 28, 2025. Yamagami admitted to the killing during his first hearing. On January 21, 2026, he was sentenced to life imprisonment.
