Japan AI Award 2026: Hakuhodo DY, Daihatsu's Mugen Tako win

The Japan AI Award 2026 is explicitly designed around a different question from most tech prizes: not what AI tool was built, but what the organization or person set out to achieve with it. That framing is visible in the winners. Hakuhodo DY Corporate Initiative did not produce a single flagship model; it built an internal movement in which employees from 13 head-office divisions made AI apps for each other, chosen for their "osekkai" spirit of noticing colleagues' burdens. By end-June, 132 development plans had been submitted, and cross-department connections in the AI promotion chat grew 3.5x year on year.

The individual grand prize went to Daihatsu's Mugen Tako, recognized for taking AI knowledge outside the company. He expanded a study group started by three people into a company-wide organization, has taught at universities since 2019, and his five online courses published over the year from November 2025 reached 6,587 learners. A member of his internal technical study group won world No.1 at Tableau Conference 2026.

The rest of the winner list shows the same breadth: Yokosuka City for a nationwide-first citywide generative AI rollout, Endo Farm for a five-employee operation that used AI for administration to run four businesses, and Toyota City Waterworks for AI-based leak and vacant-house prediction. The through-line is AI applied to everyday operational problems rather than flagship technology, which is likely why the judges emphasized vision, practice, and shared value alongside uniqueness.
