KDDI and 9 Sponsor Companies'' Digital City, Citizens Changing 2030s Social Problem Simulation

At the Osaka-Kansai Expo (opened April 13, 2025), KDDI''s "Virtual Future City" project was unveiled through KDDI''s Web3-based metaverse platform "αU (AlphaU)" — accessible anytime from anywhere to experience a near-future 2030s city. The project is the core exhibition of Japan''s government-led future society showcase "Future Life Expo," attempting citizen participatory digital experience beyond simple virtual space construction. Urban design supervised by fantasy cartographer Imaizumi Takayuki — dual structure of urban and regional city areas. Nine participating companies: Hitachi, Kubota, Kawasaki Heavy Industries, Kobe Steel, IHI, Komatsu, Kansai Electric Power, Aoki Asunaro Construction, Mitsui O.S.K. Lines — each presenting technology solutions for complex 2030s social problems (environment, population decline, labor shortage). Interactive structure: participants directly explore problems and experience solutions through embodied participation; "what if" scenarios where individual citizen choices affect urban systems in real-time simulation. The αU platform significance: KDDI''s bet that Web3 social infrastructure (persistent identity, digital ownership, community governance) creates fundamentally different engagement than Web2 virtual experiences — the Virtual Future City is simultaneously a technology demonstration, a public engagement platform for social issues, and a proof-of-concept for KDDI''s metaverse strategy. Broader significance: Japan''s industrial leaders using metaverse infrastructure for civic engagement around concrete social challenges represents a different vision of metaverse value than entertainment or retail — positioning it as democratic infrastructure for collective problem-solving.
