A major emergency operation was launched at the Ginza Six shopping complex in Tokyo on Monday after at least 19 individuals required hospitalization due to an unidentified chemical irritant. Authorities were alerted to the scene after shoppers and staff reported a sudden, strong smell permeating the ground floor of the luxury retail center.

Preliminary investigations suggest that a man deliberately sprayed an irritant substance near an ATM located within the building. Law enforcement officials believe the chemical involved likely contains capsaicin, the active component found in chili peppers, which is known to cause immediate respiratory and skin irritation. Witnesses described experiencing intense discomfort, including scratchy, painful throats and a numbing sensation upon entering the affected area.

Emergency responders, including police, firefighters, and medical personnel, arrived quickly to secure the site. Specialized teams in hazmat suits were deployed to assist those affected and ensure the area was decontaminated. While the building was cordoned off to facilitate the investigation and cleanup, authorities confirmed that they are actively searching for the suspect responsible for the incident. No arrests have been made at this time, and the investigation remains ongoing.
