Hitachi City and Hitachi, Ltd. (along with Hitachi Systems and Sawai Pharmaceutical) completed a smart city project verification involving health data of 70,000 citizens. Identifying a high prevalence of hypertension, they will launch data-driven health policies and AI-powered app features in 2026.

Hitachi City, Hitachi, Ltd., Hitachi Systems, and Sawai Pharmaceutical have announced the results of two health-focused verifications conducted in FY2025 as part of their 'Next-Generation Future City' (Smart City) co-creation project. The initiative aims to realize the 'A city where you become healthy if you live there' grand design through digital health and elderly care solutions.

Verification 1: Aggregation and Analysis of Health Data In collaboration with multiple insurers (National Health Insurance, Japan Health Insurance Association, etc.), the project aggregated statistical data from approximately 70,000 citizens, representing 75% of the local population aged 40 to 79. This large-scale analysis revealed a city-wide trend of high hypertension prevalence, providing a clear target for future intervention.

Verification 2: Promoting Health Consciousness via the 'SaluDi' App 305 citizens participated in testing the health management app 'SaluDi,' which features AI-based disease risk prediction and Personal Health Record (PHR) management. Post-verification surveys confirmed that the app is effective in improving health literacy and promoting healthy behaviors. The project will continue into FY2026 with the addition of personalized AI advice services.

Future Roadmap for FY2026 Based on these findings, Hitachi City will implement new Evidence-Based Policy Making (EBPM) measures, including support for groups at high risk of hypertension and expanded app functionalities. Through these efforts, the partners aim to align with national healthcare policies, promote PHR standardization, and extend the healthy life expectancy of citizens.
