Tetsuya Yamagami, an unemployed 41-year-old, has been identified by police as the suspect who approached Abe and opened fire during a campaign speech on Friday.
Yamagami believed Abe had promoted a religious group to which his mother made a “huge donation”, Kyodo news agency has said, citing investigative sources.
The suspect told police his mother subsequently went bankrupt, the Yomiuri newspaper and other media have reported.
Tomihiro Tanaka, president of the Japanese branch of Family Federation for World Peace and Unification, known as the Unification Church, confirmed to reporters in Tokyo that the suspect’s mother was a church member. He declined to comment on her donations.
Neither Abe nor the suspected killer were members, Tanaka said. Nor was Abe an adviser to the church, he said.
The Unification Church was founded in South Korea in 1954 by Sun Myung Moon, a self-declared messiah and strident anti-communist.
It has gained global media attention for its mass weddings where it marries thousands of couples at a time.
The church’s affiliates include daily newspapers in South Korea, Japan and the United States. Moon ran a business empire and founded the conservative Washington Times newspaper.
Reuters was not able to contact Yamagami’s mother and could not determine whether she belonged to any other religious organisations.
Abe, who held conservative views, appeared at an event hosted by an organisation affiliated with the church last September and delivered a speech praising the affiliate’s work towards peace on the Korean peninsula, according to the church’s website.
Critics have for years said the church is a cult and questioned what they say are murky finances. The church rejects such views and says it is a legitimate religious movement.
Police have confirmed that the suspect said he held a grudge against a specific organisation, but they have not named it.
Reuters visited the home of Yamagami’s mother in Nara on Monday. The white house is tucked away at the end of a quiet cul de sac in a well-to-do neighbourhood one stop on the train from where Abe was gunned down. She did not appear to be at home. Two uniformed policemen sat outside in an unmarked car.
A next door neighbour, a woman who only gave her surname Ishii, said she did not know the family and had only ever greeted the mother.
“I don’t see her around much, I say hello, but that is all,” she said, adding that the mother appeared to live a quiet life.
Another neighbour, an 87-year-old woman who only gave her surname Tanida, said the mother had lived alone for a long time.
Yamagami’s mother first joined the church around 1998 but stopped attendance between 2009 and 2017, Tanaka said. About two to three years ago she re-established communication with church members and in the last half year or so has been attending church events about once a month, he said.
Tanaka said the church learned of the mother’s financial difficulties only after talking to those close to her. He said he did not know what caused those difficulties.
Nara police on Monday said they found apparent bullet holes at a facility run by the church, and that the suspect told them he had fired practice rounds at the facility the day before he shot Abe.
