The man suspected of assassinating Shinzo Abe targeted the former Japanese Prime Minister because he believed Abe’s grandfather – another former leader of the country – had helped the expansion of a religious group he held a grudge against, according to public broadcaster NHK.
Abe’s grandfather Nobusuke Kishi, who served as Prime Minister from 1957 to 1960, was targeted for assassination in the final year of his premiership, though he survived after being stabbed six times.
“I thought that former Prime Minister Nobusuke Kishi contributed to the expansion of (the religious group), and I thought about killing his grandson, former Prime Minister Abe,” the suspect, 41-year-old Tetsuya Yamagami, told investigators, NHK reported.
“I had a grudge against a particular religious group, and I thought that former Prime Minister Abe had a close relationship with this group,” Yamagami reportedly said. “My mother got into a group and made a large donation and my family life was messed up.”
Yamagami has not been formally charged, but is being investigated on suspicion of murder after admitting to shooting Abe last Friday in the city of Nara, where the former leader had been delivering a campaign speech.
CNN has not been able to independently confirm what group Yamagami was referring to, or any links between Abe and any group the suspect harbored hatred towards.
However, on Monday, the Japan office chairman of the Family Federation for World Peace and Unification, widely known as the Unification Church, said Yamagami’s mother had been a member who attended its events about once a month.
But Yamagami himself was never a member of the church, its chairman, Tomihiro Tanaka, said in a statement.
In a news conference later Monday, Tanaka said he had learned the suspect’s mother was having financial difficulties around 2002, but added: “We don’t know what the causes were or how they affected the family circumstances.”
CNN has not been able to locate Yamagami’s mother for comment, nor determine whether she has legal representation, nor to confirm whether she was affiliated with the church – a group that was founded in South Korea and gained fame worldwide for its mass weddings, including in New York’s Madison Square Garden.
Tanaka said he was “confused” by reports of Yamagami’s alleged “resentment” toward the church.
“There is a big distance between having resentment toward our association and killing former Prime Minister Abe. We struggle to understand why this happened. We will cooperate fully with the police to reveal his motive,” Tanaka said.
He also denied that Abe’s grandfather had any role in expanding the Unification Church, saying Kishi did not take “any special measures or have any special influence on the spread of the religion at all.”
The church had received a message of support from Abe at an event it organized, but the former Prime Minister was not a registered church member, nor did he sit on its advisory board, Tanaka said.
The Unification Church, originally known as the Holy Spirit Association for the Unification of World Christianity, was founded by Moon Sun-myung in 1954. It rose to prominence in the late 1950s and early 1960s, an era of upheaval in South Korea, which at the time was transforming from a poor country torn apart by civil war to one of the world’s most modern economies.
By the 1980s the church had a global reach and it remains prominent in parts of Asia today. It continues to make international headlines for its mass weddings, in which thousands of young couples tie the knot at the same time, with some brides and grooms meeting each other for the first time on their wedding day.
Moon, known by followers as “Father Moon,” died in South Korea in 2012 at the age of 92.
Details of the killing continue to emerge as Japanese authorities investigate the suspect. Yamagami told investigators he had “made up his mind” to kill Abe a year ago, according to NHK, citing “investigative sources” on Monday.
Yamagami had used a homemade weapon, which he practiced shooting in the mountains days before the killing, according to NHK. The firearms “suited his goal of killing Abe without fail,” Yamagami said, according to NHK.
Nara police said Monday that Yamagami may have carried out a test shooting in the early hours of Thursday morning, a day before Abe’s assassination, against the building of “a certain group” in Nara prefecture.
CNN visited the building on Monday, where the entrance was clearly marked with a sign that read, “Family Federation for World Peace and Unification.”
The building was covered by blue tarpaulin and guarded by two police officers, who confirmed it had been the site of a “dangerous” incident involving gunshots, which is under investigation.
CNN was unable to view the gunshot marks on the building’s facade and did not receive explicit confirmation from police on site that Yamagami was involved in the incident under investigation.
On Monday, Nara police investigators told CNN that Yamagami is being cooperative but has not shown any remorse.
Asked whether the suspect was working alone, police said they are investigating all possibilities.
Abe’s funeral was hosted by his widow Akie Abe at a temple in Tokyo on Tuesday, with attendance limited to family members and people who were close to the former prime minister, NHK reported.
