At least two victims, including a schoolgirl, were injured in a knife-cutting operation near Tokyo on Tuesday morning.
The Japanese TV station NHK quoted officials as saying that a man with knives attacked a group of elementary school children when they boarded a school bus at 7:44 local time in Kawasaki town.
The suspect should have stabbed himself in the neck before his arrest. According to the broadcaster, he has since died of his injuries.
An eyewitness told the police that the suspect was armed with two knives on the school bus and stabbed children in succession, said NHK.
A city official said 16 people, most of them schoolgirls at a local Catholic school run by Canadian nuns, had not suffered life-threatening injuries, Associate Press reported.
"One man stabbed them," Dai Nagase, spokesman for the Kawasaki Fire Department, told AFP. "We received an emergency call at 7:44 am, killing four elementary students."
The motive for the attack is unknown.
The deadly incident occurred during the visit of President Donald Trump on the occasion of the beginning of the new reign of Emperor Naruhito.
