A 43-year-old man was arrested in Saitama for allegedly interfering with Hama-Sushi business operations.
The suspect recorded himself touching a soy sauce bottle spout and shared the video on social media.
The individual had previously received a 500,000 yen fine in June for a separate sushi-related incident.
Hama-Sushi management expressed frustration and committed to maintaining a strict stance against such malicious activities.
