Kitakyushu tests GAMA physical AI on public roads

Kitakyushu's test sits at the intersection of a buzzword and a practical problem. Physical AI — AI with a physical body that moves in the real world — is among the candidates for Japan's new-word and buzzword awards, and the city is trying to turn that attention into something operational. The demonstration, run since October 26 in the Tobata district of Yahatahigashi Ward, uses GAMA, a robot built by local startup Yamato Infra Robotics, to check whether it can safely cover about 4 kilometers of public road. In the test, GAMA recognized the color of a crossing signal and waited for green before proceeding, and when reporters approached it spoke a request to yield the path, avoiding contact.

The city frames the effort around efficiency and labor shortages, and the developer's president, Yamato Fukuzuka, describes a role in which GAMA gathers data on how far bridges and other structures have deteriorated and what repairs they need, then analyzes it to support decisions. The near-term milestone is whether GAMA can be confirmed safe without human supervision; if so, Kitakyushu wants to use it for infrastructure inspections within the next fiscal year.

Scale is part of the story: the city says 100 physical AI demonstrations are planned through fiscal 2030, suggesting this single road test is one step in a longer program rather than a one-off trial.
