A witness told NHK on Thursday that a woman fell while being chased by the suspect, who then stabbed her with a knife and shot at two police officers as they arrived at the scene in a patrol car.
The woman and the two police officers were pronounced dead at a hospital. An older woman, who was injured but could not be rescued because she was near the suspect, was found dead early today, police said.
During the standoff, TV footage showed police wearing bulletproof vests and carrying shields, with an ambulance nearby. Police sealed off a 300-metre radius around the house, and city officials urged people in the quiet farming neighbourhood to stay home.
Violent crimes are rare in Japan. It has strict gun control laws and only a handful of gun-related crimes annually. But in recent years, there have been some high-profile cases involving random knifings on subways and arson attacks, and there is growing concern about homemade guns and explosives.
