Police officers fired shots on Tuesday at a knife-wielding man on a street in the city of Saitama north of Tokyo, with one of the bullets hitting him in the abdomen.
The 68-year-old man was arrested at the scene on suspicion of obstructing officers from performing their duty. He was taken to a hospital and confirmed dead, police said.
At around 2 p.m., a woman in the neighborhood made an emergency call reporting that a man was lying on the street.
As two police officers approached him, the man suddenly picked up a knife beside him and charged at them, according to the police.
Following a warning shot, the officers each fired once with one of the bullets hitting him, they said.
