Overview

• A customer at a Sukiya branch in Tottori, Japan, discovered a dead mouse in their miso soup on January 21, 2025.
• Sukiya temporarily closed the branch for hygiene inspections and reopened two days later but did not publicly address the incident until March 22, 2025.
• The delay in acknowledging the issue fueled public criticism, especially after the image of the mouse went viral on social media.
• Zensho Holdings, Sukiya's parent company, experienced a 7.1% drop in stock value, its largest decline in over a month.
• Sukiya has introduced new hygiene protocols, including employee training and regular inspections, to prevent similar incidents and rebuild customer trust.
