Two women were killed and another person was injured in a stabbing incident at a shrine in Tokyo, with the male suspect appearing to have committed suicide, Japanese authorities said on Friday.
Shigenaga and the other woman, who was his girlfriend and believed to be in her 30s, apparently ambushed Nagako after she got out of a vehicle on the grounds of the shrine in Tokyo's eastern ward of Koto. The motive was unclear, though Japanese media reported there may have been a feud between the priest and her brother.
Police have been searching for the attacker.
The chauffeur of the shrine, who also got out of the auto, was chased by the woman who wielded a samurai sword.
Shigenaga's partner, meanwhile, chased down his sister's driver, who had tried to escape on foot, and attacked him about 100 meters away.
Police officers walk near the scene of a stabbing incident at Tomioka Hachimangu shrine in Tokyo Friday, Dec. 8, 2017. The driver's injuries were not life-threatening.
Police said the attacks had been captured by nearby security cameras and that two survival knives and two Japanese swords had been left at the scene.
According to an acquaintance of a family member, Shigenaga was the chief priest of the shrine until he was dismissed about 10 years ago.
He was arrested in 2006 after sending his sister letters with death threats, according to the Asahi daily.
Founded in 1627, Tomioka Hachimangu Shrine is located about 300 meters from Tokyo Metro's Monzen-Nakacho Station.
The almost 400-year-old Tomioka Hachimangu shrine is known for its close ties to sumo and holding one of Tokyo's three big Shinto festivals.
