Asahi Group Holdings’ beer sales in Japan fell again in January as the fall-out from the cyberattack at the company continued.

Hit by a cyberattack at the end of September, Asahi has reported another month of lower domestic beer and soft-drinks sales.

However, sales from the group’s food business increased in January, the first month of growth since the breach.

In a brief filing today (12 February), the Super Dry brewer said sales of “beer-type beverages” from its domestic Asahi Breweries unit fell 11% year-on-year in January. The company said its Super Dry volumes were down 9% on January 2025.

Meanwhile, RTD sales dropped 14% and wine by 13%. However, sales of “whiskey and spirits” grew 16%.

The Asahi Soft Drinks division, home to brands including Mitsuya and Calpis, reported a 16% decrease in sales.

The group did not provide detailed figures for its food business but said the unit saw its sales increase at a “mid-single-digit” rate.

Asahi Group Holdings said its domestic logistics operations had “normalised” from this month, “enabling shipments of all products excluding certain discontinued items and the resumption of new product launches”.

When the company announced the cyberattack in September, it reported a “systems failure”, which affected production and distribution across its domestic business. Asahi’s factories in Japan resumed operations a week later.

In November, the Peroni beer brand owner said nearly two million people could have had personal data leaked in connection with the cyberattack in Japan.
