Overview
- The footage shows a customer pouring a liquid kept in a dishwashing‑detergent container onto ordered tuna at a Hama Sushi in Saitama on May 27 and uploading the clip to social media.
- The post generated dozens of public inquiries to Hama Sushi by June 2, forcing the company to respond and prompting police to open an investigation.
- Saitama Prefectural Police arrested a 43‑year‑old unemployed man from Moroyama Town on June 2 and publicly announced the arrest on June 3; officers say he admitted he did it to increase SNS view counts.
- Authorities charged the suspect with 威力業務妨害, obstruction of business, on the basis that the online post caused operational and reputational harm, and Hama Sushi says it is fully cooperating with the probe while considering its next steps.
- The case underscores how incentives for viral content can drive deliberate harmful stunts and signals that police and companies may pursue both criminal and civil responses to similar acts.
