IBM, Fujitsu, SMBC & Softbank: Japan's Agentic Health Plan

Japanese technology firms are deploying sovereign cloud infrastructure and AI platforms to digitise the country's healthcare sector.
Fujitsu, IBM Japan, Sumitomo Mitsui Financial Group and SoftBank are building systems that prioritise data sovereignty, interoperability standards and cloud-native architectures.
The initiatives focus on creating scalable technology platforms that can integrate medical and personal health data across institutions.
According to the companies, this kind of infrastructure will be able to meet domestic data governance requirements while also supporting AI-driven applications for clinical documentation, research collaboration and personalised health services.
Sovereign cloud architecture deployment
Fujitsu and IBM Japan are constructing a sovereign cloud platform engineered specifically for healthcare institutions operating in Japan.
The platform will host electronic health record solutions from both companies while maintaining data residency and operational continuity standards.
The infrastructure creates a common technology layer for medical data utilisation across multiple institutions. Hospitals and healthcare providers can then access cloud-based medical information systems that comply with domestic data governance frameworks.
The platform architecture supports administrative workflow automation and data interoperability between systems. According to the companies, the technology could reduce operational overhead while improving access to patient information across institutional boundaries.
The initiative aligns with Japan's digital transformation strategy by establishing shared infrastructure for healthcare data management. Implementation of the platform requires integration with existing hospital IT systems and legacy EHR databases.
AI integration for clinical workflows
The partnership includes deployment of AI-powered tools for hospital operations and clinical support functions.
Fujitsu and IBM Japan plan to implement AI systems for clinical documentation generation, nursing report preparation and diagnosis procedure combination (DPC) coding automation for medical fee claims.
The AI technologies use natural language processing to automate administrative tasks that currently require manual input from healthcare staff. According to the companies, the tools could reduce documentation workloads and free up time for clinical decision-making.
The firms are also developing advanced use cases for pharmaceutical research and clinical trial management.
The technology platform will enable cross-institutional research collaboration by securely integrating healthcare data with patient consent protocols.
AI-driven systems could identify suitable candidates for clinical trials through pattern recognition across aggregated health records.
Fujitsu and IBM Japan are working with university hospitals and national medical centres to test the technology and expand deployment of AI applications for drug development and personalised medicine services.
Nationwide platform for data integration
Fujitsu has formed a technology alliance with SMBC and SoftBank to build a Japan-based healthcare platform using domestic data centres and cloud infrastructure.
The partnership focuses on data sovereignty by ensuring all medical data and personal health information remains within Japanese territory.
The platform architecture enables secure interoperability between healthcare institutions, government systems and private sector services. According to the companies, the technology could support more efficient data exchange and improve access to medical and preventive care services.
The plan of the alliance is to build an ecosystem that connects data across the patient journey, from wellness management and preventive care through to treatment and follow-up. AI-powered applications will run on the platform to provide disease risk assessment and reduce duplicate testing and interrupted treatments.
"I am truly delighted by this announcement," says Takashi Kitayama, Vice President, Head of SMBC Group Unit, Global Account Director, on LinkedIn.
"The collaboration in the healthcare sector between the SMBC Group, Fujitsu and SoftBank is a historic initiative.
"We are taking a new step forward for the future of healthcare in Japan. I've been involved in this project from the very beginning, so it's very moving for me."
AI agents and digital services
The three companies are developing app-based AI agents designed to function as personalised health partners. The AI services will utilise medical and personal health data through consent-based access controls to provide health recommendations and care management support.
The technology platform integrates with government systems including the Nationwide Healthcare Information Platform and My Number Portal. According to the companies, the integration promotes data standardisation and interoperability across public and private healthcare networks.
Each company contributes specific technical capabilities to accelerate deployment and scale. SMBC Group will integrate healthcare services with financial platforms through digital channels such as Olive, expanding payment infrastructure and wellness service delivery.
Fujitsu will develop the healthcare data platform, sovereign cloud infrastructure and AI technologies. The company is applying its expertise in healthcare-focused large language models and medical data governance frameworks.
SoftBank will build user-facing applications and domestically operated AI services. The company plans to use platforms like LINE, Yahoo Japan and the PayPay ecosystem to distribute the technology and drive adoption.
According to the alliance, the infrastructure is designed to scale to approximately 60 million users and 4,000 medical institutions, supporting both improved healthcare quality and long-term system sustainability in Japan
