For the commercialization of automated driving systems, the Council for Science, Technology and Innovation (CSTI) at the Cabinet Office has promoted numerous industry-government-academia collaborations through the Strategic Innovation Promotion Program (SIP).

The Japanese government has clarified several levels of autonomous driving. The classification standard was developed by the US non-profit organization “SAE (Society of Automotive Engineers)”, which is the most widely used in the world, and Japan has also adopted it. There are 6 levels of vehicle autonomy, ranging from Level 0 (no automation) to Level 5 (full automation). Level 2 allows the driver to take their hands off the wheel on the road but the driver is required to take control whenever necessary.

With Level 3, vehicles can perform most tasks, but humans are still required to take over when necessary. Level 4, allows autonomous driving under certain conditions, on public roads. Level 4 is a class that is intelligent as a service, but not as a means of personal transportation. Buses run unmanned on certain routes in sparsely populated areas, but, in the future, will be expanded to private vehicles and trucks on highways.

The Japanese government plans to amend traffic laws to allow category four self-driving vehicles (autonomous vehicles) to operate on some roads and expand autonomous driving lanes to fifty different locations by 2025 to help address the bus driver shortage. About 60 cities in Japan have applied to implement autonomous services.

The Japanese government’s proactive approach demonstrates Japan’s commitment to being a leader in the development and application of autonomous vehicle technology.
