An artificial intelligence system designed to identify people at risk of taking their own lives has helped prevent at least two suicide attempts after being deployed at railway stations and commercial buildings across Japan.
Developed by Tokyo-based technology company Asilla, the system uses security camera footage to analyse human behaviour and detect warning signs associated with potential suicide attempts.
The AI monitors activities such as pacing, prolonged loitering and lingering near dangerous areas, including the edges of train platforms and rooftops.
When suspicious behaviour is detected, the system immediately alerts security personnel and station staff, allowing them to intervene before a tragedy occurs. In some locations, warnings can also be broadcast through loudspeakers.
According to Asilla, the technology is currently operating at around 40 railway stations and commercial facilities throughout Japan.
In one incident, the AI flagged a man who had entered a restricted area inside a commercial building. After receiving an alert, a security guard approached the individual and spoke with him.
The man later revealed that he had planned to end his life by jumping from the building.
In another case, the system detected a child spending an unusually long period near a railing on an upper floor of a facility.
A security officer was dispatched to investigate and later discovered that the child had been writing a suicide note.
The intervention allowed staff to step in before any harm occurred.
Beyond suicide prevention, the technology has also been developed to recognise other situations requiring urgent attention, including medical emergencies, individuals who have become immobile and incidents involving violence.
Asilla said the AI system has been trained using approximately seven million pieces of security camera footage collected through collaborations with around 200 commercial facilities and organisations since 2022.
The company believes the technology can play a significant role in improving public safety by helping staff identify vulnerable individuals and respond more quickly to potential emergencies.
The deployment of AI-powered monitoring systems continues to expand in Japan as businesses and transport operators explore new ways to enhance safety and prevent tragic incidents before they occur.
