A 42-year-old man in Hamamatsu, Shizuoka Prefecture, was arrested early Friday morning for allegedly stabbing a woman to death on a street, police said.
Kenichi Matsuzaka turned himself in shortly after the stabbing, which took place in Hamamatsu at around 10:20 p.m. A passer-by witnessed the attack and reported it to the police.
Investigators are trying to identify the victim, who appeared to be in her 40s. She had been stabbed more than 10 times in the breast and neck, leading the police to believe the suspect had clear intent to kill. The woman was pronounced dead at a hospital.
The male witness who reported the crime told investigators he heard a woman cry out in a loud voice. When he rushed toward her, he saw her covered in blood.
When Matsuzaka turned up at the police station, he also had bloodstains on him, police said.
The stabbing took place some 300 meters southeast of Saginomiya Station on the Enshu Railway in western Shizuoka. The area is dotted with rice paddies and residences.
