A former priest wielding a samurai sword killed his Shinto priestess sister and another woman in an apparent family vendetta at a historic Tokyo shrine, before turning the blade on himself, police told AFP Friday.
Police said that Nagako Tomioka, the 58-year-old head of Tomioka Hachimangu shrine, was attacked as she got out of her vehicle Thursday night.
While Shigenaga was assaulting his sister, another woman - reportedly the attacker's wife - pursued Nagako's driver with a sword. The motive was unclear, though Japanese media reported there may have been a feud between the priest and her brother. He received injuries not considered life-threatening, police said.
Nagako Tomioka's driver, 33, was also seriously injured in the attack.
The brother is then believed to have killed the woman before committing suicide.
The two attackers then moved to the shrine premises, where the Shigenaga Tomioka stabbed his accomplice in the chest and stomach and then stabbed himself in the left side of the chest multiple times.

Mr Nicholls took to Twitter to announce both his concession and that he will "not seek to continue as LNP leader". A total of 50 seats have been declared in the Queensland election so far, with Labor winning 28 of those seats.
The driver escaped but suffered deep cuts to his shoulder, arm, and chest, police said.
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.
Also, a woman aged in her 30s who was with Shigenaga Tomoika attacked and stabbed the driver of the auto with a Japanese sword, police said.
Shigenaga Tomioka was arrested some 10 years ago for blackmailing his sister.
The shrine, established in 1627, is known for its annual Fukagawa Hachiman festival, one of Tokyo's three major festivals from the Edo period.
