Major security incidents announced in July 2026 included a disruption caused by unauthorized access to NICHIREI's internal systems. The company announced that the incident affected refrigerated warehouse receiving and dispatch operations and Nichirei Foods' frozen food shipments. It was also reported that the incident may have affected the servers and customer data of multiple companies, underscoring the need for companies to strengthen their information security measures.
Nihon Kotsu confirmed an external malware infection on its internal systems in the early hours of 11 July. Its chauffeur-service web order and reservation management system and some internal systems were temporarily unavailable. The company disclosed the scope of the damage and the period of impact and is working to prevent a recurrence.
Around 15 July, Sagawa Express confirmed a display issue on Smart Club, its member-only web service. Names, email addresses and inquiry numbers different from the customers' actual information were displayed. Unauthorized access by a third party was ruled out, and an investigation continued amid the possibility that the personal information of approximately 70,000 people had been affected.
