“Only 15 minutes” What happened on the train
The incident happened shortly thereafter.
While driving between Chofu Station and Fuda Station, a 72-year-old man who was in the third car, which is the eighth car from the beginning, was suddenly stabbed with a knife.
Regarding the situation at this time, the suspect stated that "I immediately took out the knife from the bag and stabbed the man's right chest while sitting".

It took only 15 minutes from the time the suspect boarded the limited express train to his arrest.
Suspect “Refer to the case of Odakyu Line in August”
This incident is very similar to the one that happened inside the train on the Odakyu Line in August.
First of all, the time zone is about 8:30 pm for the Odakyu Line incident and about 8 pm for this incident, which changes only about 30 minutes.
In each case, the scene was on the train heading to the city center.
In particular, the rapid express and limited express trains, which have few stations to stop, were aimed at.
The same is true for attacking passengers with a knife, moving around the train, sprinkling the oil brought in, and igniting the fire.
According to investigators, Hattori responded to the investigation by saying, "I wanted to kill a person and be sentenced to death. I was thinking of mass murder, but the Odakyu Line incident occurred in August, so I will try to refer to it. I thought, "he said.
"I thought that passengers couldn't escape because the limited express train had a long stop. In the case of the Odakyu Line, cooking oil was used and it didn't catch fire, so I prepared oil for lighters this time." It means that you are making a statement.
Suspect's acquaintance “gentle and unobtrusive”
According to an acquaintance man who was in the same class as Hattori in elementary and junior high school, he belonged to the track and field club in junior high school and was a shot put player.
His personality is quiet and unobtrusive, and he tends to lose contact after entering a public high school in Fukuoka Prefecture.
Many of the elementary and junior high school classmates last met the suspect at the coming-of-age ceremony four years ago, and there was nothing unusual at that time.
An acquaintance man said, "When I met him a few years ago, he said,'I'm working as a long-term care worker.' After that, I sent a message on SNS, but I didn't get a reply. I didn't know it at all. I was really surprised to hear about the incident because I wasn't the type to go out to the city during Halloween because it was quiet. "
A passenger at the station where the suspect was arrested "I'm scared to get on the train"
Kokuryo Station on the Keio Line where the limited express train stopped urgently and the suspect was arrested.
On the morning of the day after the incident, there were many people who used to commute to work or school.
A woman in her 50s who uses the station for commuting said, "I thought it would be scary to get on the train because the incident had just happened, so I thought about using a bicycle, but it would take time, so I couldn't do it. I was shocked by the Odakyu Line incident, but I never thought that this would happen on the route I use. " rice field.
Also, a mother in her thirties with a baby living nearby said, "I learned about the incident from an acquaintance. I sometimes take a train with my child, so if I get involved in the incident at that time I'm scared when I think about it. In the future, I'll never take my eyes off my child in the train. "
SNS post “How do you get away from the window with your child?”
In response to the incident, posts such as "I'm afraid to get on the train" are being posted on SNS one after another.
Some of them say, "It's a closed room in the train and you can't escape. If you're on a limited express, you won't stop for a long time and you're scared." It seemed that many people were running away from the window, but how should I run away with my child? "
Reasons for "platform doors that did not open"
As pointed out on SNS, passengers were seen escaping from the window.
Why did this happen?
According to Keio Electric Railway, just before stopping the train at Kokuryo Station, passengers used a cock to open the door in an emergency, so acceleration was automatically controlled and the train stopped as a safety measure.
For this reason, the train stopped before the normal stop position, and the train door and the platform door of the station were out of alignment.
The conductor did not decide to open all the doors because passengers could not safely go down to the platform if the doors opened in this situation, and the station staff also took measures such as opening the platform doors for the same reason. It means that it wasn't.
The use of the "emergency notification device" could not be immediately grasped.
According to the Ministry of Land, Infrastructure, Transport and Tourism, in this case, the "emergency notification device" was used in about 1 minute after leaving Chofu Station.
The "emergency notification device" is a device that allows passengers to notify the conductor of an emergency from inside the train, and is installed at the front, rear, and next to the door of many trains in the Tokyo metropolitan area.
By using this device, the driver and conductor noticed an abnormality in the car, and one minute later, they stopped at the next Kokuryo station.
However, because the passenger who pressed the button on the device left the site for evacuation, the driver, conductor, and station staff could not grasp the situation until they heard from other passengers what was happening in the car.
Also, according to the Ministry of Land, Infrastructure, Transport and Tourism, the train that had this incident did not have a security camera installed inside the train.
Chief Cabinet Secretary Matsuno “Instructed to take all possible measures to ensure railway safety”
At a press conference on the morning of the 1st, Chief Cabinet Secretary Matsuno said, "We recognize that this is an extremely vicious and vicious incident. I am aware that I have instructed the prefectural police to strengthen cooperation with business operators and take all possible measures to ensure the safety of railways. "
He added, "We would like to further strengthen cooperation between railway companies and related ministries and agencies so as not to allow recurrence, and continue to promote efforts to prevent illegal activities."
Chief Cabinet Secretary Matsuno said, "In order to ensure the safety of public transportation, we are steadily advancing efforts such as installing security cameras and properly operating emergency notification devices, and at the same time, we are taking appropriate evacuation measures for passengers, which has become an issue this time. We would like to create an environment where people can use public transportation with peace of mind by securing the above. "
Strict management with the new corona What are the safety measures for railway operators?
The Ministry of Land, Infrastructure, Transport and Tourism has put together measures for railway operators in response to the incident in which passengers were cut off on the Odakyu Line in August, but the railway companies, which continue to be harsh due to the effects of the new coronavirus, have responded. The adjustment was difficult due to the opinion that it was difficult.
Many of the security cameras installed on trains do not have a mechanism to check the images in real time, so the Railway Bureau of the Ministry of Land, Infrastructure, Transport and Tourism responds by making it possible to check the images inside the train even outside the train when an abnormal situation occurs. I asked you to consider speeding up.
According to the people concerned, some railway companies have shown their understanding of the necessity and effectiveness, but "Large-scale capital investment cannot be made while the large deficit continues due to the corona wreck" and "The government takes measures. Will you pay for it if you press for it? "
For this reason, the summary was limited to the expression "using smartphones and tablets to share information in real time among related parties including commands," and did not require in-depth measures such as networking of security cameras.
In addition, it is difficult for everyone to carry out baggage inspection at ticket gates, which has been controversial for some time, on the railroads used by many people, and there are problems with the accuracy of inspection equipment, so it is included in the measures. did not.
As a result, measures such as strengthening patrols by security guards at stations and trains were shown, but measures such as extension so far were shown, but this incident occurred just over two months later, and the country And railway operators will be forced to review their measures.
