Fujitsu Limited and IBM Japan, Ltd. have officially formalized their healthcare-sector collaboration following discussions first disclosed in September 2025, with the companies planning to jointly advance cloud infrastructure and AI-driven healthcare services in Japan. The partnership will focus on developing a sovereign cloud platform designed for medical use while enabling broader utilization of healthcare data across institutions. Through the initiative, both companies intend to operate their electronic health record systems on Fujitsu’s sovereign cloud environment, supporting secure cross-institutional data integration and expanding the application of AI technologies based on the operational requirements of healthcare providers. The companies said the effort is intended to provide healthcare institutions with cloud-based systems that maintain data sovereignty while supporting operational continuity and stronger security standards. The initiative also seeks to address mounting structural pressures within Japan’s healthcare system and improve long-term sustainability. Medical AI is expected to support a range of hospital operations under the collaboration.
Japan’s healthcare sector continues to face growing strain as the country’s aging population increases demand for medical services. Medical costs have risen beyond 48 trillion yen annually, while healthcare providers are dealing with staffing shortages, financial pressures, and broader sustainability concerns within the social security system. At the same time, medical data required for advanced clinical research remains insufficiently standardized and fragmented across institutions, limiting broader utilization. Fujitsu and IBM Japan said easing the administrative burden on healthcare workers and enabling more efficient use of medical data across organizations will be essential for improving care delivery. Under the collaboration, the companies will jointly promote operational efficiency initiatives while supporting medical DX measures encouraged by the Japanese government. Their sovereign cloud platform will serve as a common foundation for healthcare applications provided by both companies, enabling medical institutions to adopt cloud-based systems with stronger control over data management and security.
The companies also plan to integrate and jointly utilize their AI technologies for the healthcare industry. With consent from healthcare providers and patients, Fujitsu and IBM Japan aim to securely combine data from multiple medical institutions in Japan to improve clinical and operational workflows. Planned use cases include AI support for preparing clinical and nursing reports as well as streamlining DPC coding processes linked to medical fee claims. The collaboration is also exploring initiatives connected to drug discovery and clinical development, including identifying patients eligible for clinical trials and improving research efficiency. By expanding cooperation with university hospitals, national centers, and other medical institutions, the companies intend to validate healthcare data and AI applications before phased deployment. Medical AI will also support future patient-centric services covering appointment booking, treatment processes, and post-care follow-up.
