Japan Enhances Healthcare Cybersecurity as Hospitals Designated Critical Infrastructure
Japan’s Health, Labor and Welfare Ministry has announced plans to enhance cybersecurity measures for hospitals, driven by the increasing frequency of cyberattacks targeting medical facilities.
What Drives the Enhanced Cybersecurity Measures for Hospitals in Japan?
Medical institutions face significant challenges in implementing robust cybersecurity frameworks due to the complexity of interconnected medical devices and IT systems.
Many hospitals operate with multiple vendors managing different technologies, creating numerous external network entry points. These connections complicate monitoring and response efforts, increasing exposure to threats. The ministry’s strategy focuses on reducing these external connections to streamline network management and enable faster isolation of compromised systems during attacks.
How Will the ₹826 Crore Budget Be Allocated?
The budget will fund initiatives to secure hospital networks and deploy cybersecurity professionals.
A key component involves encouraging hospitals to consolidate their external connections, which will be supported through a government-led framework aimed at strengthening national resilience. Institutions may contract private firms for this work, with subsidies determined by factors such as hospital size, including bed capacity. The funding aligns with broader national goals to enhance cybersecurity across critical sectors.
What Cybersecurity Threats Have Targeted Japanese Hospitals?
Ransomware attacks have become a persistent threat to Japanese healthcare providers.
In 2022, Osaka General Medical Center experienced a cyberattack that disrupted its electronic health record system, leading to restricted surgical and outpatient services. More recently, in February 2026, Nippon Medical School Musashikosugi Hospital suffered a breach exposing the personal data of 130,000 patients. These incidents highlight the urgency of strengthening defenses to prevent similar disruptions.
What Role Will Cybersecurity Specialists Play in Hospital Protection?
The ministry plans to establish a system for deploying cybersecurity experts to hospitals during incidents.
Given the limited resources of medical institutions to maintain in-house specialists, the initiative will connect facilities with external professionals when needed. These experts will be assigned based on the specific requirements of each hospital, ensuring timely intervention during cyber incidents.
Will Staff Training Be Part of the Cybersecurity Strategy?
In addition to technical measures, the plan includes funding for staff training programs.
The goal is to improve hospital personnel’s ability to recognize and respond to cyber threats. By combining direct support from specialists with ongoing education, the ministry aims to build long-term resilience against evolving attack methods.
Why Has Healthcare Been Classified as Critical Infrastructure?
Japan’s revised economic security law now categorizes healthcare as critical infrastructure, emphasizing the need for heightened protection.
This designation reflects the sector’s vital role in national stability and public safety. The government’s broader cybersecurity strategy now prioritizes safeguarding medical systems, ensuring continuity of care during cyber incidents.
Which Hospitals Will Benefit From the New Measures?
The initiative targets 88 advanced treatment hospitals with 400 or more beds, as defined by the amended law.
These facilities will receive dedicated cybersecurity resources, including specialist personnel and network upgrades. Under the fiscal 2027 budget, approximately 20 hospitals will undergo inspections to assess their readiness and implement necessary improvements.
