On Monday, Asahi Group Holdings, Japan’s largest brewery and a global beverage company, experienced a significant cyberattack that caused a system-wide failure in its domestic operations. While the company has not officially confirmed ransomware encryption, investigative authorities have reported it as an apparent ransomware attack. Asahi has stressed that the incident is limited to its operations in Japan, with no impact on its international branches in Europe, Oceania, and Southeast Asia. At present, there is no confirmed leakage of personal or customer data.
About Asahi
Asahi Group Holdings, founded in 1889 in Osaka, is Japan’s largest beer manufacturer, holding about one-third of Japan’s beer market. Known for its flagship Asahi Super Dry, the company produces a wide range of alcoholic and non‑alcoholic beverages, including beer, whisky, soft drinks, cider, and mineral water under brands such as Nikka Whisky, Mitsuya Cider, Peroni, Pilsner Urquell, Grolsch, and Fullers. Employing around 30,000 people, Asahi operates in Japan, Europe, Oceania, and Southeast Asia, producing approximately 100 million hectoliters annually, with 2024 revenues of about $20 billion USD, reflecting its global stature in the beverage industry.
The Cyberattack
The Asahi Group experienced first noticed the cyberattack on the 29th of septemver. The attack led to a system-wide failure affecting its operations in Japan. The company has not officially confirmed that the attack involved ransomware encryption, and no external party has taken responsibility for the incident. The company is actively investigating the cause of the attack and working to restore operations, though it has not provided an estimated timeline for recovery. At present, there is no confirmed leakage of personal or customer data, and the incident is limited to operations within Japan.
Operational Impact of the Attack
The cyberattack has resulted in widespread disruption across Asahi’s domestic business. Approximately 30 factories throughout Japan have halted production, affecting the manufacture of beer, beverages, and food products. Order processing and shipment systems have been suspended nationwide, and all call centers and customer service desks have gone offline. In some locations, employees have reverted to manual operations, taking orders by telephone and processing data without access to normal IT systems. The attack has caused operational glitches rather than isolated shutdowns, meaning that some processes are intermittently affected, further complicating recovery efforts.
Product Launches and Market Concerns
The attack has forced Asahi to postpone the October launch of twelve new beverage and food products, with no new release date announced. These delays will affect the earliest planned release date of October 6. Liquor wholesalers and retailers have expressed concern about shortages, noting that competitors would find it difficult to quickly fill the gap created by this disruption. Japan accounts for roughly half of Asahi’s profits, making these domestic disruptions particularly costly and raising concerns about broader supply chain impacts in the beverage market.
Company Response and Investigation
Asahi has publicly acknowledged the incident, issuing an apology to customers and business partners for the inconvenience. The company is actively investigating the cause of the cyberattack and working to restore operations, though it has not provided an estimated timeline for recovery. Under Japan’s Active Cyber Defense Law, Asahi has reported the incident to investigative authorities. The attack has also disrupted external communications, as the company is currently unable to receive outside emails, further complicating order processing and recovery efforts.

Prolonged downtime could impact not only Asahi but also wholesalers, retailers, and consumers across Japan.

The company also added that they have no timeline on when the operation will resume. It was confirmed that the systems failure was only limited to their Japanese operations.
