A cyber attack has hit a Japanese refrigerated logistics provider that serves major food chains, including Kentucky Fried Chicken (KFC) Japan, threatening store closures and menu restrictions.
With approximately 140 distribution centers, Nichirei is Japan’s largest cold storage warehousing company with about 5,000 clients and a market value of about $3.2 billion or 525 billion Japanese Yen.
Nichirei learned of the cyber attack on July 13, 2026, after experiencing system failures and launched an investigation that determined unauthorized access had occurred.
Cyber attack on logistics provider disrupts Japanese food chains
Nichirei has warned that the cyber attack could disrupt its subsidiaries’ and clients’ operations. KFC Japan has also confirmed that the cyber attack could lead to temporary store closures or the removal of some menu items due to ingredient shortages. The popular food chain says all 1,300 restaurants could be affected. It also suspended mobile ordering and delivery as a result of the cyber attack.
Nichirei also provides refrigerated logistics services to other food establishments, including supermarkets. Kura Sushi Inc., a popular sushi chain operating in over 700 locations across Japan, has also warned of potential shortages that could lead to closures.
Renowned snack vendor Ezaki Glico has also disclosed that its ice cream business depends on Nichirei’s logistics. According to local sources, Nichirei’s cyber attack could affect up to 20% of its deliveries. However, the snack giant said it was seeking alternative delivery partners to mitigate the impact of the cyber attack. Japanese restaurant chain Colowide has also reported shipment delays as a result of the Nichirei cyber attack. Other affected chains include Hotto Motto, Yayoi Ken, Aeon, and TableMark.
According to Donald McFarlane, Advisory Board Member, Xcape, one logistics provider’s cyber risk could have cascading effects on thousands of businesses and their customers.
“Had the disruption been broader, the consequences could have extended far beyond limited menus. Critical infrastructure security must follow a simple discipline: find material exposure before an adversary does, fix it, and prove the risk actually went down,” McFarlane noted.
Meanwhile, Nichirei has assured its customers that it was working to restore impacted systems with the assistance of external cybersecurity forensics experts.
So far, Nichirei has not disclosed the identity of the threat actor or whether it had received ransom demands. Similarly, the attack vector exploited remains unknown at the time of publication. Nichirei also said it was withholding some technical details for safety reasons. However, phishing, stolen or compromised authentication credentials, and the exploitation of security vulnerabilities remain the most common initial access methods.
Nevertheless, the refrigerated logistics provider has disclosed that the breached servers stored personal information and has notified the Personal Information Protection Commission. However, an investigation to determine whether the cyber attack leaked personal data was still ongoing, and the company would notify impacted individuals. For now, the logistics provider has disconnected the affected servers to protect personal information from unauthorized access.
“This incident highlights how cyberattacks against operational technology and logistics providers can have immediate real-world consequences,” warned Phil Wylie, Senior Consultant & Evangelist, Suzu Labs. “While many organizations focus on protecting customer data, attacks that disrupt the availability of critical business systems can be just as damaging. In this case, the ripple effects extended from a single refrigerated logistics provider to thousands of restaurants, retailers, and food manufacturers that depend on timely deliveries.”
Japan’s supply chain targeted
The cyber attack on Japan’s logistics provider Nichirei adds to a growing list of incidents affecting the country’s supply chains.
In 2025, a ransomware attack hit Japan’s beverage producer Asahi, resulting in widespread shortages. In the same year, online retailer Muji was forced to suspend operations following a ransomware attack that impacted its logistics provider Askul.
In July 2023, the Japanese Port of Nagoya was hit by a ransomware attack that disrupted cargo distribution, forcing auto giant Toyota to suspend operations at an export packaging facility.
“As attackers increasingly target supply chains to maximize disruption, resilience has become just as important as prevention. The organizations that recover the fastest are those that have already planned for the possibility that a critical partner will be temporarily offline,” concluded Wylie.
