The article argues that 20 TSE-listed stocks at the intersection of medical DX and security should be monitored from now, citing the cyberattack at Nara Municipal Nara Hospital and the government's digitalization initiatives.
The article details an incident at Nara Municipal Nara Hospital in Nara City, where a network monitoring device detected suspicious external communications late at night on 21 April 2026. Servers, including the electronic medical record system, were disconnected from the network, temporarily halting emergency and outpatient admissions before normal medical services resumed 3 days later. It also refers to a university-affiliated hospital where a ransomware attack resulted in the leakage of personal information belonging to approximately 130,000 people, citing it as a real-world example of how a cyberattack can bring hospital functions to a halt.
Regarding government policy, the article explains that amendments to the Medical Care Act and related legislation enacted in December 2025 legally stipulate a target of nearly 100% electronic medical record adoption by the end of 2030. It also says that the FY2026 medical fee schedule incorporates cybersecurity measures into its requirements, including the Electronic Medical Information Sharing System Development Add-on. In addition, it characterizes this as a period in which investment in digitalization, including security measures, is being supported through medical fee reimbursements.
