Why Japan is about to run out of its favorite beer

• Japan is running low on its fan favorite Asahi Super Dry beer.
• Asahi Group Holdings was hit with a cyberattack this week, which has halted its operations.
• Retailers like Family Mart and 7-Eleven have warned that their alcohol stocks may be in low supply.

Japan is slowly running dry of its favorite beer, Asahi Super Dry.

Asahi Group Holdings said in a news release on September 29 that it was “experiencing a system failure caused by the cyberattack, affecting operations in Japan.”

According to several news outlets, the attack halted Asahi’s production in a majority of its 30 production facilities in Japan, and the company has been unable to resume operations since September 29.

In the release, it added that while no leakage of customer data had been confirmed, its order and shipment operations in Japan had been suspended. Its call center operations, including customer service desks, were also paused.

“The system failure is limited to our operations within Japan,” it said in the release. The company said it had no estimated timeline for recovery.

Asahi Group Holdings, which is known for its Asahi Super Dry beer and also owns the Italian beer brand Peroni, is based in Tokyo. The company reported first-half 2025 sales of 1,360 billion yen, or about $9.24 billion.

Asahi’s stock price has been down more than 6.5% in the past five days and about 7% in the past year.

Japanese retailers like Family Mart have warned that Asahi alcohol stocks may be in low supply following the attack.

“Following the cyberattack that occurred on Monday, September 29, 2025, Asahi Group Holdings, Ltd. has temporarily suspended orders and shipments of Asahi Group products, with no prospect of resumption,” Family Mart said in a statement on Thursday.

It said that due to the suspension, its own private bottled beverages are expected to be in short supply in stores.

Bloomberg reported that shoppers in Japan’s 7-Eleven stores saw notices that shipments of the Super Dry beer and Asahi’s other products, such as Mitsuya Cider soda, had been suspended.

Representatives for Asahi did not respond to a request for comment from Business Insider.
