Japan Pushes AI-Based Autonomous Driving Framework with New Level 2++ Certification Plan

Japan is accelerating efforts to establish a stronger policy and regulatory foundation for autonomous driving technologies as the country seeks to expand intelligent transport systems and artificial intelligence-based mobility solutions. The Research Commission for the Promotion of Intelligent Transport Systems and Highways under the Liberal Democratic Party held a meeting on May 26 to finalize recommendations focused on enabling the large-scale realization of autonomous driving technologies across the country.

The recommendations were prepared in response to the rapid development of end-to-end autonomous driving technologies that utilize AI for vehicle decision-making and operational control. The commission plans to request that the government introduce a dedicated safety evaluation methodology capable of assessing increasingly advanced autonomous systems. Authorities are also considering targeted support measures for successful autonomous driving businesses whose operational models can be replicated across multiple industries and regions.

A major element of the proposal involves the establishment of a certification framework for “Level 2++” advanced driver assistance systems. The proposed category is intended for systems that require minimal driver involvement during operation while still remaining below fully autonomous driving classifications. Policymakers believe that a dedicated certification structure could help standardize advanced driver assistance deployment while improving public confidence in emerging AI-driven vehicle technologies.

The meeting also reviewed recommendations developed by the commission’s autonomous driving subcommittee for inclusion in the government’s growth strategy expected later this summer. The recommendations outline several priority areas that will guide future autonomous mobility initiatives and public-private cooperation efforts throughout the country.

Key Areas Covered in Japan’s Autonomous Driving Recommendations

Government officials and industry stakeholders are expected to continue discussions around institutional support mechanisms, infrastructure readiness, and AI-related regulatory standards as autonomous mobility technologies mature. The recommendations indicate that Japan intends to position itself as a leading market for next-generation intelligent transportation systems while balancing innovation, safety evaluation, and logistics modernization requirements.

Frequently Asked Questions

What is the proposed Level 2++ autonomous driving certification in Japan?
The proposed Level 2++ certification is designed for advanced driver assistance systems that require very limited driver involvement during operation. It would create a regulatory category between current assisted driving technologies and higher autonomous driving levels. The framework aims to improve safety standardization, establish clearer evaluation procedures, and accelerate adoption of AI-based driving technologies across passenger mobility and logistics applications in Japan.

Why is Japan focusing on end-to-end AI autonomous driving technology?
Japan is focusing on end-to-end autonomous driving because AI-based systems are rapidly improving vehicle decision-making, operational efficiency, and driving automation capabilities. Policymakers believe these technologies can help address transportation challenges, improve regional mobility services, and strengthen logistics operations. The government also sees autonomous driving as a strategic growth area that can support intelligent transport systems and future automotive innovation initiatives.
