A FHIR server, 'FRUCtoS,' supporting Japan-specific profiles, is provided and being implemented in medical institutions through two versions: single-tenancy and multi-tenancy. The product aims to promote the utilization of Japanese medical information, realizing a world where it can be easily accessed.
This article explains 'HL7 FHIR,' an international standard for safely exchanging patient information between medical institutions. FHIR acts as a common language allowing different vendor systems to communicate, positioning it as the core technology for both electronic medical record sharing services and standardized EHRs.
This paper, featuring researchers from various universities and companies, summarizes the activities and outcomes of the FHIR Study Group. It provides the latest research findings in medical informatics, expected to contribute to future data utilization infrastructure development.
The standardized electronic medical record is redefined not as a single product, but as a connected healthcare information infrastructure. It requires a design philosophy that utilizes cloud SaaS and standards like HL7 FHIR to achieve flexible linkage from minimal core functions to external services.

This study aimed to establish methodologies for effective healthcare data utilization, addressing technical and systemic challenges associated with FHIR adoption. By referencing USCDI, the research proposed multi-faceted approaches, including resolving discrepancies between diagnostic and insurance diagnoses, and integrating standards (Standard) with AI.
A group associated with the Japan Association of Medical Informatics (JAMI) has published a FHIR ValueSet based on ICHI, an international classification for health interventions. This enables standardized handling of procedure codes within Japanese electronic medical record systems.
The JAMI Standards Committee has established the 'ePath HL7 FHIR Study Group.' This group aims to create a FHIR specification based on existing JAMI standard specifications, with the goal of achieving JAMI standardization and applying for HELICS guidelines.
JCHO Hokkaido Hospital has launched a pilot program utilizing standard smartphones and on-premise generative AI to automatically draft clinical notes. The goal is to reduce documentation time and mitigate physician burnout.
A FHIR ValueSet (jp-condition-severity-vs) for indicating Condition severity in Japan has been published. This provides a foundational structure for uniformly handling condition severity information across medical institutions and systems, promoting standardization in Japanese electronic health records and information exchange systems.
The Japan Association for Medical Data Utilization Infrastructure (IDIAL) will hold a specialized modeling training seminar starting November 2025. The seminar aims to teach practical skills, including information model construction using UML and mapping to HL7 FHIR.
The activities of the FHIR Domestic Implementation Study Group 2 (Diagnostics and Observation) were presented at a medical informatics conference. This abstract summarizes the group's efforts, indicating progress toward standardization and practical application within Japanese healthcare information systems.
The Japan HL7 Association and the Japanese Society of Medical Informatics have published FHIR CodeSystem specifications defining 'Encounter Category' for health checkup reports. This provides a standardized code system for electronic exchange of health screening data.
A FHIR specification and implementation guide are provided for handling specific health checkup results. This aims to offer a standardized data structure for medical information exchange, thereby enhancing interoperability between systems.
The Japan Society for Medical Informatics has released the FHIR implementation guide, 'JP-CLINS,' concerning electronic health record information sharing services. This guide provides technical specifications for handling patient summaries and document data, contributing to the standardization of data linkage in Japanese medical institutions.
The Japan Society for Medical Informatics presents a concrete example of sharing allergy information (saba/mackerel) within the electronic medical record service using FHIR format. This technical specification defines how specific allergen data (fish) should be recorded based on the JP-CLINS guidelines.
The FHIR Japanese implementation research working group in Japan Association of Medical Informatics (JAMI) has released the specification (v1.2.0) for the NamingSystem 'jp-medicationunitmerit9-namingsystem'. This system aims to standardize medication unit abbreviations, providing a foundational standard based on the FHIR specification for use in Japanese healthcare settings.
The Japan Society for Medical Informatics has published a new NamingSystem (jp-medicationsubstitutionnotallowedreason-namingsystem) defining the 'Reason that Medication Substitution is Not Allowed' for electronic medical record information sharing. This contributes to standardizing clinical information and improving interoperability.
The FHIR Japanese implementation research working group (JAMI) has released the HL7 FHIR Japan Core ImplementationGuide v1.2.0. This guide provides diverse resources, including local development builds, definitions (JSON/XML), sample data, and list data (CSV/Excel), establishing a foundation for standardization and implementation in Japanese healthcare IT systems.
A working group from the Japanese Association of Medical Informatics (JAMI) has released an implementation example for body measurement data, such as weight, based on the HL7 FHIR standard. This serves as a technical guideline for standardized healthcare data exchange within Japan.
