Description
On July 13, 2026, Nichirei, a Tokyo‑headquartered frozen food producer that also operates cold storage warehousing and maintains a global presence through 80 subsidiaries, reported a cyberattack on its systems. The company responded by disconnecting its information networks on the same day to contain the incident. This action halted operations at Nichirei Logistics Group’s refrigerated warehouses and at Nichirei Foods’ shipping operations. The disruption extended to multiple restaurant chains, retailers, and delivery services that rely on Nichirei’s logistics, as noted in local media coverage. Nichirei stated that the attack was directed at its servers and that some of the affected systems contained personal information.
On the following Thursday, Nichirei issued a statement (PDF) indicating that it would begin a gradual restoration of the impacted operations starting the next Friday, though it did not specify when full service would be resumed. The firm’s investigation confirmed that hackers had targeted its servers as part of the attack. Because personal data may have been stored on the compromised systems, Nichirei submitted an initial report to the Personal Information Protection Commission regarding the possibility of a data leak. The company said it would continue its investigation and, should any leakage be confirmed, would promptly notify the relevant parties. Nichirei also noted that it is withholding further details of the cyberattack as a precautionary measure, so it remains unclear whether the incident involved a known ransomware or data‑extortion group. In parallel, the company is assessing the potential impact of the incident on its consolidated financial results and has stated that it will disclose any material impact once the assessment is complete.
