Japan's Fujitsu Demonstrates 'Social Digital Twin' Technology: Simulates 250,000 Individual Behaviors, Targets FY2027 Transport Application
Japanese tech giant Fujitsu demonstrated its 'Social Digital Twin' technology at CEATEC 2026, which combines AI and behavioral economics to simulate individual evacuation behaviors for 250,000 people, with plans to commercialize it for transport sectors by fiscal year 2027.
Japanese electronics giant Fujitsu demonstrated its 'Social Digital Twin' technology at the CEATEC exhibition held from October 13 to 16, 2026. The technology combines artificial intelligence with principles of behavioral economics to reproduce the specific behavior patterns of every individual in a city within a digital space.
A live demo at the event featured a fictional disaster scenario based on Toho's 'Godzilla' IP: approximately 250,000 people, including local residents, tourists, and non-Japanese speakers, were gathered around Kawasaki Station. The system simulated their evacuation process one hour before Godzilla's arrival. Participants could choose strategies such as multilingual guidance and traffic control to observe changes in crowd flow among different demographic groups.
According to Fujitsu staff, the core of the technology lies in building probability models for populations with different attributes using public data (such as census records) and movement statistics, thereby generating high-precision social simulations. Although the demo focused on disaster prevention, the company stated that its primary application scenario is public transportation planning, such as bus route reorganization.
Fujitsu noted that pilot experiments have been conducted with some municipalities to verify the alignment between simulation results and actual pedestrian flow data. The company plans to apply this technology to the transport sector by fiscal year 2027 to address challenges in maintaining public transit due to Japan's aging population and labor shortages.
