Japan's Saitama holds station riot drill

The video shows an actor playing the gangster wearing a black coat and sunglasses waving a knife in his hand, and then the police and staff came on stage and used tools to subdue the "gangster". According to reports, about 70 police officers and station staff at the scene participated in the drill.
In recent months, there have been repeated violent attacks in stations and trains in Japan. Just yesterday (15th) afternoon, a stabbing incident occurred at Fukushima Railway Station in northeastern Japan. The victim was a woman in her 80s, and her life was not in danger.
On the evening of October 31, a man set fire to a knife in a train on the Keio Line in Tokyo, Japan, injuring 17 people, one of whom was seriously injured and unconscious. The man, dressed in the "Joker" costume from the "Batman" series of comics, first stabbed a 72-year-old passenger in the seat with a knife on the train, then poured out the oil in the lighter and set it on fire. The carriage caught fire. The Tokyo Metropolitan Police Department has arrested a 24-year-old suspect on suspicion of attempted murder and is investigating the details of the case.
On November 8, local time, a 69-year-old man set fire on the seat of the "Sakura No. 401" train of the Kyushu Shinkansen, claiming to imitate the "clown case". No casualties were caused, but more than 50 trains were still affected.
In August this year, a stabbing incident occurred on a Tokyo train, injuring nine people, one of them seriously. The suspect surrendered after fleeing the scene. It also happened in August this year, when a man poured a suspected sulfuric acid liquid on pedestrians at a Tokyo subway station, injuring two people.
