Fujitsu and IBM Japan partner on sovereign cloud platform for medical data integration

Fujitsu and IBM Japan have formalised a healthcare collaboration to develop a sovereign cloud platform for medical use and jointly utilise medical AI solutions. The partnership will run electronic health record solutions on Fujitsu's sovereign cloud, enabling data integration across multiple institutions while ensuring data sovereignty within Japan.

Fujitsu and IBM Japan have formalised a collaboration within the healthcare domain, promoting the development of a sovereign cloud platform for medical use and joint utilisation of medical AI solutions, according to an official announcement. The two companies will run their electronic health record solutions on Fujitsu's sovereign cloud platform, enable data integration across multiple medical institutions, and facilitate AI utilisation based on healthcare providers' needs in Japan. The collaboration aims to provide healthcare institutions with a cloud-based medical information system option that ensures data sovereignty by allowing control over technologies used within Japan.

Fujitsu is a Japanese information and communications technology company, while IBM Japan is the Japanese subsidiary of American technology company IBM. Japan's healthcare system faces increasing medical demand due to a rapidly aging society, with medical expenses exceeding 48 trillion yen annually. Challenges include sustainability of social security funding, decreasing medical personnel, and financial difficulties for medical institutions. Medical data required for advanced clinical research and development is still in the process of standardisation and structuring, yet to be sufficiently integrated and effectively utilised.

This development matters for Japan's healthcare industry, where addressing structural challenges requires burden reduction for healthcare professionals from administrative and indirect tasks, enabling them to focus on clinical duties. Medical data must be appropriately utilised across multiple institutions with careful consideration of data sovereignty, security, and operational continuity. The collaboration builds on considerations first announced in September 2025.

For the healthcare technology industry, the partnership combines Fujitsu and IBM Japan's strengths to provide effective solutions to healthcare providers. Stakeholders including medical institutions, healthcare professionals, and patients stand to benefit from improved data integration and AI-driven clinical research capabilities, while ensuring data sovereignty within Japan's regulatory framework.
