In Japan, an AI system has been introduced in approximately 40 train stations and commercial buildings to prevent people from jumping and committing suicide, and it has been reported that the system has been able to save the lives of at least two people.
The system, developed by Tokyo-based Asilla Inc., continuously monitors people's movements through security cameras and can immediately distinguish whether suspicious behavior such as pacing back and forth on the platform edge or building roofs, or lingering for extended periods, indicates suicidal intent or not.
When the AI system detects such suspicious behavior, it simultaneously sends alerts to security personnel and issues warnings, and in some locations, audio announcements are made through loudspeakers.
In one life-saving incident, the AI detected a man in a restricted area of a commercial building, allowing security personnel to arrive in time to intervene. The man later admitted he was preparing to jump from the building and take his own life.
In another alarming case, the AI noticed a child lingering for an extended period on the rooftop railing of a building. When security personnel investigated, they were able to prevent the child from completing a suicide note that was already being written.
Since 2022, Asilla Company has been training the AI system in detail using over 7 million security camera records from partnerships with approximately 200 commercial buildings.
As a result, this system is capable of not only detecting suicide indicators but also monitoring sudden falls, health emergencies, and violent incidents such as assaults.
Currently, the AI system is installed and operational in approximately 30 commercial buildings and 10 train stations within Tokyo and the neighboring Kanagawa Prefecture.
