Japan’s most popular beer is running low after cyberattack disruptions at Asahi Breweries forced critical systems offline. Asahi, the company behind the world-famous Super Dry beer, has been struggling to restore normal operations five days into the outage.

The company confirmed that its order, shipment, and call center systems were suspended due to the cyberattack, which has been linked to a ransomware incident. While Asahi has begun manually processing some orders, large-scale shipments are still delayed, leaving Japan on the brink of a nationwide beer shortage.

Asahi Struggles To Restore Beer Supply

Asahi Group released a statement explaining that system-based orders and logistics remain disrupted, with no clear timeline for recovery. The company acknowledged it was targeted by ransomware but withheld further details “to prevent additional damage.”

Customers and distributors are already reporting delays, raising concerns as Asahi Super Dry — Japan’s best-selling beer — becomes harder to find on store shelves. The outage is confined to Japan, but it highlights how cyberattacks can disrupt supply chains in industries beyond tech.

Ransomware Attack Raises Data Security Concerns

In its latest update, Asahi confirmed signs of a potential unauthorized data transfer linked to the attack. Investigators are now working to determine whether sensitive information may have been compromised.

“We took immediate action to contain and respond to the incident,” Asahi said. “Traces suggest a possible transfer of data, and we are continuing to investigate the scope of the impact.”

What This Means For Consumers

For now, Asahi is relying on manual order processing to keep beer flowing, but production and delivery remain slow. If system recovery takes longer, Japan’s most popular beer shortage could worsen — especially with demand surging during the fall festival season.

This incident not only disrupts everyday consumers but also underscores the rising risks of ransomware attacks on global food and beverage companies. Asahi has not confirmed when its systems will be fully operational again.
