Quick Takeaways
- Japan has defined a coordinated public–private roadmap to accelerate real-world deployment of Level-4 autonomous driving trucks on highways.
- The initiative prioritizes standardization, external support infrastructure, and live highway trials to enable scalable autonomous freight operatio
Japan moved a step closer to commercial deployment of Level-4 autonomous driving trucks as a national public-private initiative outlined its roadmap for real-world adoption. The program, known as Road to the L4, presented a structured approach focused on standardization, operational readiness, and highway logistics, aiming to enable scalable and safe autonomous freight transport.
Building a Unified Framework for Level-4 Autonomous Driving Trucks
The initiative is developing two core documents designed to support large-scale deployment. These include an autonomous truck implementation guidebook and a dedicated roadmap that defines how Level-4 autonomous driving trucks can be introduced into society. A central objective is to remove fragmentation by aligning technical specifications, operational rules, and support systems across stakeholders.
By promoting common standards, the program seeks to reduce barriers for logistics operators, manufacturers, and infrastructure providers while accelerating commercial adoption.
Industry Collaboration to Enable Highway Operations
Participation from commercial vehicle manufacturers and trading partners ensures that the roadmap reflects real operational needs. The project concentrates on highway freight transport, where autonomous driving offers strong efficiency and safety benefits. Insights gathered from multiple demonstration trials are being consolidated to identify technical challenges, regulatory gaps, and operational constraints.
This collaborative structure allows lessons from field testing to directly inform deployment strategies for Level-4 autonomous driving trucks.
External Support Systems Required for Autonomous Trucks
A major focus of the initiative is defining the external infrastructure and support mechanisms required for autonomous truck operations. These elements are being systematically organized to ensure consistency and reliability during real-world deployment.
Key areas under development include:
Together, these components form the backbone of a scalable ecosystem for Level-4 autonomous driving trucks.
Live Highway Trials Planned in the Kanto–Chukyo Corridor
In the second half of the current fiscal year, autonomous trucks are scheduled to operate on the Kanto–Chukyo highway corridor. These live trials will validate the framework under actual logistics conditions and help refine operational guidelines before broader rollout.
The results are expected to play a decisive role in shaping Japan’s approach to commercial autonomous freight transport and future regulatory alignment.

A major focus of the initiative is defining the external infrastructure and support mechanisms required for autonomous truck operations. These elements are being systematically organized to ensure consistency and reliability during real-world deployment.
Key areas under development include:
- Specifications for relay and transfer areas along highways
- Support systems for safe lane merging
- Predictive traffic and road information services
- Remote operational monitoring and oversight
