Under the “Medical DX Vision 2030,” Japan is advancing EHR standardization and data coordination. At its core are the government-provided standard EHR and the Electronic Health Record Information Sharing Service. This article maps out the big picture and where a hospital's cloud migration fits.
What is the standard EHR?
The standard EHR is developed and provided by the government (MHLW) as a type of EHR that can connect to the information-sharing service. Operationally, the comprehensive portal of the Japan Health Insurance Claims Review & Reimbursement Services acts as the gateway. Development targets primarily medical clinics without an EHR, and an alpha version began in March 2025.
The information-sharing service and the 3 documents / 6 data items
The Electronic Health Record Information Sharing Service is a mechanism for sharing clinical information between medical institutions. The scope of sharing is defined as the “3 documents and 6 data items.”
- 3 documents: referral letter / discharge summary / health-checkup result report
- 6 data items: diagnoses, allergies, infections, contraindicated drugs, test results, and prescriptions (confirm exact names in official notices)
These data are standardized using the international HL7 FHIR specification so they can be exchanged between systems. Nationwide full-scale operation is expected to proceed in stages during FY2026 after model-project validation and refinement.
The adoption goal toward 2030
The government has set a goal of “achieving roughly 100% EHR adoption by 2030.” This trajectory pushes EHRs, once largely on-premise, toward standardization and cloud adoption.
Relationship to hospital cloud migration
Conforming to standards and participating in data sharing favors systems that update continuously. A cloud-based EHR keeps up more easily with regulatory changes and new sharing requirements, aligning well with the medical-DX trajectory toward 2030.
Summary
The standard EHR and the information-sharing service underpin the Medical DX Vision 2030. Details will be updated through future notices, so official confirmation is a prerequisite — but the direction toward standardization and cloud is clear. Sakigake Platform supports migrating a hospital's systems as a whole onto a cloud foundation in line with this trend.
