Cyberattack Disrupts Asahi Group Holdings' Operations in Japan

Asahi Group Holdings, Japan's largest brewing company, has suspended all domestic operations following a cyberattack that began on September 30, 2025. The attack has led to significant disruptions in order processing, shipping, and customer service across its 30 breweries in Japan. Asahi, known for its flagship Asahi Super Dry beer and other beverages, confirmed that there has been no leakage of personal or customer data to external parties.

The cyberattack has halted production at all of Asahi's domestic factories, affecting the company's ability to meet regional demand. As a result, the launch of 12 new products has been postponed, and operations are being handled manually at some locations. The disruption has raised concerns about potential shortages of popular products, including Asahi Super Dry, Nikka Whisky, and Mitsuya Cider, as the beer industry is particularly sensitive to supply chain interruptions due to freshness requirements.
