Tokyo, October 3, 2025 — Japan’s largest brewer, Asahi Group Holdings, is grappling with a severe beer shortage following a crippling ransomware attack that began in late September 2025. The cyberattack has forced the suspension of production, order processing, and shipments across most of the company’s domestic operations, threatening supply chains nationwide.
Cyberattack Brings Production to a Halt
According to Asahi Group, the ransomware attack targeted its core IT systems, crippling ordering and distribution processes across its network of 30 factories in Japan. While the physical brewing operations remain intact, the inability to manage orders and shipments has effectively halted deliveries to retailers.
Retail giants such as 7-Eleven, Lawson, and FamilyMart have already reported dwindling stocks of Asahi Super Dry — the company’s flagship beer — with some outlets posting notices to inform customers of the shortage. “We expect stock to run out within days unless operations are restored,” said a Lawson spokesperson.
Impact on Consumers and Retailers
The shortage is expected to impact beer sales nationwide, particularly as Asahi Super Dry is one of Japan’s most popular beer brands. Convenience stores, supermarkets, and izakaya pubs — where Asahi Super Dry is a staple — are preparing for potential shortages in the coming days.
Asahi is currently prioritizing essential products, including food and soft drinks, for distribution. However, alcoholic beverages have been placed on hold due to logistical constraints caused by the cyberattack. This prioritization has fueled concerns among businesses reliant on Asahi’s beer supplies.
A Tokyo-based bar owner said, “Our orders for Asahi Super Dry have been delayed indefinitely. Customers who come in expecting it may be disappointed.”
Asahi’s Response and Recovery Efforts
The brewer has confirmed it is working closely with cybersecurity experts to contain the attack and restore systems. “We are making every effort to resume normal operations as quickly as possible,” the company stated in a public announcement. However, no definitive timeline has been provided for a full recovery.
Experts note that ransomware attacks on major manufacturing companies are on the rise globally, with attackers exploiting vulnerabilities in IT networks. “This incident highlights the critical importance of robust cybersecurity in manufacturing and logistics,” said cybersecurity analyst Hiroshi Tanaka.
Economic and Market Implications
The shortage comes at a challenging time for Japan’s beverage industry, which is already facing rising costs and supply chain disruptions. Analysts predict that prolonged production stoppages could significantly affect Asahi’s revenue and market share, potentially benefiting competitors such as Kirin and Sapporo.
Consumers may also face higher prices for beer if the shortage continues, as supply constraints push retailers to adjust pricing. In addition, the incident may lead to a broader reevaluation of cybersecurity investments in the Japanese manufacturing sector.
The Asahi Group ransomware attack underscores the vulnerability of critical production systems to cyber threats. As recovery efforts continue, consumers and businesses alike face uncertainty over the availability of one of Japan’s most iconic beers. The coming weeks will be crucial in determining whether Asahi can restore operations quickly enough to avoid a long-term shortage.
