While Asahi reports that all of its Japanese facilities, encompassing six breweries, have partially resumed operations, computer systems remain compromised. This has drastically reduced the volume of shipments leaving its factories. Sakaolath Sugizaki, owner of Ben Thai restaurant in Tokyo, noted that she is receiving substantially fewer deliveries, with larger clients prioritized, leaving only four bottles of Asahi Super Dry on her shelves.
The repercussions extend beyond bars and restaurants. Convenience stores and supermarkets across Japan, including locations in Tokyo and Hokkaido, are reporting dwindling stocks of Asahi products, spanning not only beer but also bottled water and other beverages. Hisako Arisawa, a Tokyo liquor store owner, fears prolonged shortages, anticipating at least another month of limited supply.
Ransomware Group Claims Obligation
The Qilin ransomware group has asserted responsibility for the attack,a notorious entity known for targeting major organizations and operating an attack-for-hire platform. While Asahi has not publicly disclosed the specific nature of the cyberattack,they confirm that data suspected of being compromised has surfaced online. This incident joins a growing list of recent cyberattacks that have impacted global firms,including Jaguar Land Rover and Marks and Spencer,as well as disruptions to European air traffic and a port terminal in Nagoya,Japan in 2024.

Japan’s Cybersecurity Challenges
Experts point to a combination of factors contributing to Japan’s vulnerability to cyberattacks. Despite its reputation for technological advancement, the nation faces a shortage of skilled cybersecurity professionals and comparatively low levels of digital literacy within businesses. A striking example of this was the government’s continued use of floppy disks for official documents until recently.
Cartan McLaughlin from Nihon Cyber Defense Group argues that Japan’s reliance on older systems and a high degree of trust make it an attractive target for hackers. Many organisations lack robust preparedness and are more inclined to pay ransoms, further incentivizing attacks.
Government Response & New Legislation
The Japanese government acknowledges the issue and is taking steps to enhance its cybersecurity capabilities. Chief Cabinet Secretary Yoshimasa hayashi affirmed that the Asahi attack is under examination. Earlier this year, Japan enacted the Active Cyber Defense law (ACD), granting authorities expanded powers to share information with companies and proactively counter cyber threats by neutralizing attackers’ servers.
| Area Affected | Impact |
|---|---|
| Asahi Production | Reduced to manual processes, significantly lowered output. |
| Retailers (Bars, Restaurants, Stores) | Shortages of Asahi products, including beer, water, and soft drinks. |
| Cybersecurity Infrastructure | Exposed vulnerabilities,highlighting the need for investment. |
Pro Tip: For businesses, regularly backing up data to offline storage and implementing multi-factor authentication can significantly mitigate the impact of ransomware attacks.
Despite these efforts, concerns remain as businesses like Ben Thai and consumers across Japan brace for continued disruptions. Owner Sakaolath Sugizaki expressed uncertainty regarding future deliveries, echoing the anxieties of many awaiting the full restoration of Asahi’s operations.
Understanding the Rise of Ransomware
Ransomware attacks have surged globally in recent years, evolving from opportunistic attacks to complex, targeted campaigns. The average ransomware payment increased to over $1 million in 2024, and the healthcare and manufacturing sectors have been particularly vulnerable. (Source: SonicWall Ransomware Report 2024). The financial motivation behind these attacks continues to drive their proliferation.

What specific operational areas within Asahi Shuzo were most substantially impacted by the shift to paper-based processes?
Brewing Giant Asahi Reverts to Paper-Based Processes After Cyber Attack Compromise
The scope of the Cyberattack & Initial Response
Asahi Shuzo, the renowned Japanese brewer behind Asahi Super Dry, has taken the drastic step of reverting significant portions of it’s operations to paper-based systems following a sophisticated cyberattack. The incident, confirmed on october 10th, 2025, compromised key IT infrastructure, impacting production planning, inventory management, and distribution logistics. While the company hasn’t publicly disclosed the full extent of the breach, sources indicate a ransomware attack was likely involved, though no ransom demands have been confirmed.
The immediate response focused on isolating affected systems to prevent further spread of the malware. However, the complexity of the attack and concerns about lingering vulnerabilities led Asahi to implement a temporary, but considerable, shift back to manual processes. This decision, while disruptive, prioritizes maintaining production and fulfilling orders during a critical period. This incident highlights the growing threat of cybersecurity in manufacturing and the potential for significant operational disruption.
