■About the “FY2023 Supplementary Budget Project for Acceleratinng the Social
Implementation of PHR(Survey and Demonstration Project for Issues and Points of Discussion
In Creating PHR Use Cases through information Collaboration Infrastructure)”＜Background and Purpose＞
In recent years, various services using Personal Health Records (PHR)—which include information fromhealth checkup results such as weight, blood pressure, and blood sugar levels, as well as health andmedical information obtained from wearable devices and sensor equipment, such as diet, exercise, andsleep—have been provided by private businesses. As Japan faces the challenges of a declining birthrate,
an aging population, and population decline, the importance of utilizing PHR for prevention and healthpromotion is increasing. From the perspective of extending healthy life expectancy and addressing presymptomatic illness, there are expectations for the creation of new industries and the improvement ofexisting products and services.
As part of a broader government initiative, the Medical DX Promotion Headquarters, led by the Prime
Minister, was established in October 2022. Discussions on promoting medical digital transformation (DX),including the utilization of PHR, have begun, and measures to realize medical DX are being steadily
implemented in cooperation with relevant ministries and agencies. Additionally, in July 2023, the PHR
Service Business Association, a cross-industry organization, was established, indicating a growing
momentum for PHR utilization not only within the government but also in the private sector.
In this context, the Ministry of Economy, Trade and Industry is promoting the "FY 2023 Supplementary
Budget Project for Accelerating the Social Implementation of PHR (Survey and Demonstration Project forIssues and Points of Discussion in Creating PHR Use Cases through Information CollaborationInfrastructure)." This project aims to further accelerate the social implementation of PHR. The findings
from this demonstration project will be presented to the public at the 2025 Osaka-Kansai Expo
(hereinafter referred to as "the Expo") to raise public awareness of PHR. Additionally, the project willaddress and clarify the challenges and key points related to the actual social implementation of PHR
services and products.

＜Project Overvies and Schedule＞
Through this demonstration project and the Expo, themed "Designing Future Society for Our Lives,"
which will be held starting in April 2025, we aim to connect various PHRs and services in an environment
open to both businesses and the public. This initiative will lay the foundation for a future where businesses
create new products and services, and citizens use them with confidence, leading to richer lives andexperiences. We will work towards realizing a "society where people can naturally become healthier"through the utilization of PHR.
During the project period, we will empirically implement mechanisms to provide use cases utilizing PHR
through an information collaboration platform. This will be done in cooperation with PHR providers andservice providers across various themes such as exercise, sleep, and diet.

Project Concept Diagram
We will proceed with the concretization of use cases and their connection to the information collaboration
platform. In February 2025, we plan to hold a demonstration event where participants can experience andevaluate these use cases. Additionally, starting from April 2025, we aim to expand the number of PHR
service users by providing opportunities for the public to experience the created use cases at the Expo.
