Shiobara, who claims to live near the scene, is accused of attempting to murder the 70-year-old man by slashing his face and wrist with a knife. A nearby office worker said a colleague witnessed the attack. "He had two or three long-bladed weapons and was wearing goggles. He was chasing someone when a man called out, 'What are you doing?' and then the attacker turned and stabbed him." Another witness said Shiobara was wearing a survival mask and had a survival knife about 30 centimeters long hanging from his waist. "I took off the belt, removed the knife, and threw it aside," the witness recalled. The attack occurred during the evening rush hour, and aerial footage showed bloodstains on the sidewalk and police investigators examining the area. One of the recovered weapons was found in a brown case, with several others nearby. An eyewitness recounted the frightening scene: "The knife was quite long. He was swinging it around. When one man fell, he got up and was attacked again. Even when he tried to crawl away, the attacker came after him. It was terrifying."
