Tokyo, Japan – Asahi Group, Japan’s largest brewer and beverage producer, has been unable to resume operations across its domestic factories following a cyberattack that disrupted its order, shipping and support systems.
The firm operates 30 factories in Japan, manufacturing beer, beverages, and food products. While some production remains suspended, the full extent of the disruption—whether all factories have been affected—is still under investigation.
Asahi previously announced the suspension of order processing, shipment services and call centre functions due to a system outage caused by the attack. The company has confirmed that no personal data breaches have been detected so far.
At this stage, Asahi has not provided an estimate for when normal production might resume.
With roots dating back to 1889, Asahi has since expanded into a major global beverage company. Its portfolio includes Asahi Super Dry, Nikka Whisky, Mitsuya Cider, and various non-alcoholic brands, as well as international labels such as Peroni, Grolsch and London Pride.
The group continues investigating the cause of the breach while working to restore the affected systems and services across its network.
Further updates are expected once Asahi provides additional information.
Updated on October 06, 2025, Asahi Group Holdings has confirmed that the disruption to its domestic operations resulted from a ransomware attack.
The company has established an Emergency Response Headquarters and engaged external cybersecurity experts to manage the incident and restore affected systems. Initial investigations have found signs of a potential unauthorised data transfer, with efforts underway to determine the nature and scope of any compromised information.
While system-based order and shipment processes remain suspended, Asahi has initiated partial manual operations to maintain product supply and plans to gradually resume call centre services during the week of 6 October.
Atsushi Katsuki, president and group CEO of Asahi Group, stated that the company continues its investigation to further deterimine the nature and scope of the potential unauthorised data trasnfer and prevent further threats.
“We are making every effort to restore the system as quickly as possible, while implementing alternative measures to ensure continued product supply to our customers,” Atsushi commented.
