A major cyberattack on Japan’s top brewer Asahi has disrupted production nationwide, highlighting how vulnerable even large corporations remain to growing cyber threats. The ransomware incident serves as a warning for both industry leaders and government agencies to reinforce their digital defenses.
The ransomware group Qilin claimed responsibility for the cyberattack, halting operations at nearly 30 factories and freezing shipments of Asahi Super Dry beer and other beverages. Although brewing has restarted, full recovery is expected to take weeks. Qilin said it stole 27GB of sensitive company data, including contracts, budgets, and personal information.
Experts say this cyberattack underscores the lack of preparedness across Japan’s corporate sector. While Japan is known for advanced robotics, it struggles with a shortage of cybersecurity experts and aging digital infrastructure. Government data shows ransomware incidents rising sharply in 2025, with recovery costs also increasing.
Chief Cabinet Secretary Yoshimasa Hayashi vowed to strengthen defenses after the Asahi data breach. Japan’s new cybersecurity law, enacted in May 2025, empowers agencies to coordinate better responses to future cyberattacks. Experts also warn that advances in artificial intelligence make ransomware automation more efficient and widespread.
Analysts describe the Asahi cyberattack as a wake-up call for Japan’s private sector. Businesses must not only invest in prevention but also build strong recovery strategies and cooperate with incident response providers.
