OSAKA — 2021 · Major Tragedy

The Kitashinchi Psychiatric Clinic Arson

ClosedSources: ALast updated: 14 October 2026

On the morning of 17 December 2021 a deliberately set fire broke out in a psychiatric clinic on the fourth floor of the Dojima Kita Building in Osaka's Kitashinchi district. A counselling session for patients preparing to return to work was under way, and many people were inside. Twenty-six people were killed, most from carbon monoxide poisoning. Security footage showed a 61-year-old former patient carrying bags of flammable liquid into the clinic. The suspect was also badly injured and died on 30 December. With the suspect dead, the investigation was closed in 2023 without an indictment. The attack renewed debate about buildings with only a single escape route.
