More than 20 people are reported to fall ill after an unknown substance is allegedly sprayed in Tokyo’s Ginza shopping area on Monday. Multiple outlets say the incident occurs near a luxury department store and around the Ginza Six shopping complex. Victims report sudden symptoms, including sore throat and throat pain, shortly after the spraying. Japanese fire department officials say the substance is not identified and that a suspect is involved, though details of the person and the material are not described in the reports. Authorities take the affected people to hospital for assessment, with some sources characterizing the number as “more than 20” or “dozens.” The reports consistently describe the location as Ginza, a central and upscale district, and emphasize that the substance remains unknown as emergency services respond. Investigations are ongoing to determine what was sprayed, who is responsible, and the cause of the symptoms. The reports do not provide information on specific injuries beyond throat irritation or the current condition of those hospitalized.
