The Nichirei cyberattack has disrupted food deliveries across Japan after the frozen food and logistics provider confirmed its servers were compromised in a cybersecurity incident involving unauthorized access. The attack affected logistics operations supporting KFC Japan, forcing temporary service disruptions while the company investigates the incident and works to restore systems.
Nichirei Corporation said it detected system failures on July 13 and established an emergency response headquarters the same day. “Nichirei Corporation (the “Company”) experienced system failures on July 13, 2026, and has since been investigating its cause. The Company hereby announces the facts identified through the investigation to date and the measures it plans to take going forward,” reads notice issued by Nichirei.
An investigation later confirmed that company servers had been targeted in a cyberattack. While the company has not disclosed technical details to prevent further damage, it said recovery efforts are underway with the support of an external cybersecurity specialist.
Nichirei Cyberattack Disrupts Logistics and Food Shipments
Following the attack, Nichirei disconnected systems across the Nichirei Group to protect customer and business partner data. The decision disrupted inbound and outbound operations at Nichirei Logistics refrigerated warehouses and halted frozen food shipments handled by Nichirei Foods.
The company said it plans to gradually resume affected operations from July 17 after implementing additional security measures.
Nichirei also confirmed that some affected servers contained personal information. As a precaution, it submitted an initial report to Japan’s Personal Information Protection Commission regarding the possibility of a personal information leak.
The company emphasized that, as of its latest update, there is no confirmed evidence that personal information or customer data has been exposed externally. Investigations remain ongoing, and Nichirei said it will notify relevant parties if any data leakage is confirmed.
Nichirei Cyberattack Impacts KFC Japan Store Operations
The incident quickly spread beyond Nichirei’s own operations, affecting KFC Japan, which relies on Nichirei Logistics to deliver ingredients to stores nationwide.
According to KFC Japan, deliveries have been disrupted since July 14 following the unauthorized access at its logistics partner. As inventory levels fluctuate, customers may experience product shortages, limited menu availability, shortened operating hours, or temporary store closures.
The restaurant chain also temporarily suspended mobile orders, delivery services, coupons, and online ordering through its official website and mobile application.
KFC Japan said it is working closely with Nichirei Logistics and other partners to restore normal operations as quickly as possible. However, it has not provided an estimated timeline for full recovery.
Investigation Continues Into Japan Cyberattack
Nichirei said the financial impact of the incident is still being assessed. The company expects to release its first-quarter financial results for the fiscal year ending December 31, 2026, on August 7 as scheduled unless further developments require additional disclosure.
The company added that it will continue investigating the cyberattack on Nichirei and release additional information if material findings emerge.
The incident follows a series of recent Japan cyberattack disclosures involving major organizations.
Earlier this week, The Cyber Express reported that Nihon Kotsu experienced a malware-related security incident that disrupted taxi dispatch services after portions of its IT infrastructure were taken offline.
Earlier this month, The Cyber Express also reported cyber incidents involving Aflac Japan, KDDI, Sapporo Holdings, and Nidec. While those cases affected different industries, attackers frequently gained access through subsidiaries, overseas operations, or third-party infrastructure rather than directly compromising corporate headquarters.
Separately, Asahi Group Holdings continues recovering from a ransomware attack that significantly disrupted online ordering and shipment operations, forcing the company to rely on manual processes.
Supply Chain Risks Remain in Focus
The Nichirei cyberattack highlights how attacks on logistics providers can quickly evolve into broader supply chain disruption affecting downstream businesses and consumers.
Although Nichirei has begun restoring operations, investigations into the incident remain active. Authorities are also continuing to examine whether any personal information was compromised while the company works to return logistics services and KFC Japan operations to normal.
With multiple high-profile cyber incidents affecting Japanese organizations in recent weeks, the latest disruption highlight he growing operational impact of attacks targeting critical logistics and supply chain infrastructure.
