Autonomous a2z Deploys ROii Level 4 Shuttle in Japan's Hyogo

South Korea's Autonomous a2z has begun a month-long trial of its driverless ROii shuttle in Toyooka, Hyogo, its first run on public roads abroad.

Autonomous a2z, a South Korean physical AI company, started a Level 4 autonomous bus trial on 9 November in the Kinosaki hot spring district of Toyooka, Hyogo Prefecture, using its in-house ROii platform. It is the first time the company has put ROii on public roads outside South Korea.

ROii is designed without a driver's seat as a pure Level 4 driverless shuttle and carries up to 11 passengers, including standing riders. For Japan, a2z converted the vehicle to right-hand drive for left-side traffic, obtained local regulatory-relaxation certification, and passed the requirements for a regular license plate and a driver qualification test. During the trial the interior has been adjusted to accommodate a safety driver, and large sliding doors have been fitted with tourists in yukata and elderly riders in mind. The company's fleet management system (FMS) and on-site technicians will handle monitoring, emergency response and driver training.

Route and schedule

The shuttle covers about 1.8 km one way, from Kinosaki Onsen Station to near the Kinosaki International Arts Center. It runs from 9 November to 4 December, on weekdays only, three times a day and free of charge. Toyooka, which faces shrinking bus services and a driver shortage because of depopulation and ageing, is launching its first autonomous driving trial. The city will test how a shuttle copes with roads shared by pedestrians and cars, and whether it can improve mobility for residents and visitors.

Consortium and next steps

The project is run by a consortium of Japanese partners. Trading house Kanematsu leads it and handles vehicle introduction and maintenance. Local operator Zentan Bus drives the vehicle in service. Sompo Japan supplies autonomous-driving insurance and its SOMPO ALCS risk assessment solution, while KDDI and KDDI Smart Mobility build the communications and remote monitoring infrastructure.

A2z, Kanematsu and Sompo Japan plan to use the trial data to explore a full Level 4 service in Toyooka and to extend the model to other Japanese municipalities with mountain areas and tourist sites that lack transport options.

The move follows a memorandum of understanding with Kanematsu in August 2025 and a participation in an autonomous taxi trial in Naruto, Tokushima, in February this year. CEO Han Ji-hyung said the trial lets the company verify ROii's performance and stability in a different traffic environment, and that it will build a foundation for commercial Level 4 services in Japanese regional transit.
