Hitachi City and Hitachi Ltd. to Promote New Health Policies Based on Large-Scale Data Analysis of 70,000 Citizens and AI App Verification

Hitachi City (Mayor: Haruki Ogawa), Hitachi, Ltd. (President & CEO: Toshiaki Tokunaga), Hitachi Systems, Ltd. (President: Takehiko Watanabe), and Sawai Pharmaceutical Co., Ltd. (President: Toshiomi Nakate) conducted two verification projects in FY2025. These projects were part of a co-creation initiative to realize a 'smart city where living makes you healthy.'

In Verification 1, the partners collaborated with five major health insurers in Hitachi City to aggregate statistical data for approximately 70,000 people, covering about 75% of the population aged 40–79. This large-scale analysis revealed a significant local trend toward hypertension across the city.

In Verification 2, 305 citizen volunteers used 'SaluDi,' a health management app integrating AI-based disease risk prediction and Personal Health Record (PHR) management. Post-use surveys indicated an improvement in health literacy and confirmed the app's potential to encourage healthy behaviors.

For FY2026, the project will continue with the addition of an AI-based personalized advice service to the app. Based on the data, the partners will formulate new policies, including support for those at high risk for hypertension, aligning with national EBPM and PHR standards to extend citizens' healthy life expectancy.
