A police officer shot and wounded a 21-year-old man who allegedly robbed a convenience store in Koshi, Kumamoto Prefecture, before advancing on officers with a kitchen knife on the evening of 22 July. Video from the scene showed the man facing an officer who had drawn a handgun while still holding the knife. The officer fired, apparently hitting him in the leg, but he continued to brandish the weapon. Police repeatedly ordered him to drop the knife before moving in to restrain him. Another officer then used a baton to knock the knife from the suspect's hand, allowing officers to take him into custody. The suspect was identified as 21-year-old Shion Maeda, who lives nearby and is unemployed. He was arrested at the scene on suspicion of obstructing the performance of official duties.
