Asahi beer sales in Japan fall again in January as cyberattack impact persists
Asahi reports renewed declines in beer and soft drink sales as lingering cyberattack disruptions weigh on domestic performance.
JAPAN – Asahi Group Holdings reported another decline in beer sales in Japan in January, as the fallout from a cyberattack on the company’s systems continued to weigh on domestic performance.
In a statement, the Japanese beverage group, which also owns the Peroni brand internationally, said sales in its home market declined further across both beer and soft drink categories.
The company attributed the weakness to ongoing supply chain and distribution disruptions following the cyberattack.
The brewer said sales of “beer-type beverages” from its domestic unit, Asahi Breweries, fell 11% year-on-year in January. Volumes of its flagship Super Dry brand were down 9% compared with January 2025.
Other alcohol categories also recorded declines. Ready-to-drink (RTD) beverages saw sales fall 14%, while wine sales dropped 13%. In contrast, the company said sales of “whiskey and spirits” increased 16% during the month.
The Asahi Soft Drinks division, which manages brands such as Mitsuya and Calpis, reported a 16% year-on-year decline in sales. Asahi did not disclose detailed figures for its food business but said the segment posted sales growth at a “mid-single-digit” rate.
The group said domestic logistics operations “have returned to normal starting this month,” allowing the shipment of all products except some discontinued items and the resumption of new product launches.
The cyberattack, which occurred in September, caused system failures that disrupted production and distribution across Japan. Although plants resumed operations after about a week, Asahi said the impact on supply chains and sales extended into subsequent months.
In November, the company disclosed that nearly two million people “could have had personal data leaked” in connection with the cyberattack in Japan.
