In a tragic incident, a mass stabbing occurred at a care facility for people with disabilities in Sagamihara, Kanagawa Prefecture, Japan, where nineteen individuals lost their lives. The perpetrator, Satoshi Uemura, entered the facility and assaulted residents with a knife during the early morning hours. It was reported that Uemura had previously been employed at the facility, which raised questions about safety protocols and mental health resources available to both staff and residents. The attack unfolded quickly, with authorities responding to the incident after receiving emergency calls.

Uemura's motivations were revealed in subsequent investigations; he expressed extremist views about people with disabilities, suggesting they should be put to death for the perceived burden they place on society. This statement sparked a nationwide debate regarding the treatment and rights of individuals with disabilities in Japan. Following his arrest, Uemura was charged with multiple counts of murder and attempted murder. The event prompted discussions about the societal perceptions of disabilities and mental health, as well as the adequacy of existing laws regarding knife attacks and mass violence.

In the aftermath, many in Japan mourned the victims and called for reform in mental health support and the treatment of the disabled community. The incident also led to increased discussions among advocacy groups seeking to raise awareness of the rights of individuals with disabilities, aiming to prevent any further violence and discrimination. Vigil services were held across the country in memory of the victims, emphasizing compassion and inclusion in society and the need for greater awareness and support.
