Safety standards/standards for automated driving

GOJ has incorporated the new UN Regulations for automatically-driven new vehicles (R155/R156/R157). On the other hand, for the CS/SU management systems (MS) of the vehicles in use including organization requirements, additional approval must be obtained in Japan.


  • For the CS/SU upon software modification for vehicles in use, Japan should accept COC (Certificate of Compliance) of UN-R155/R156 obtained overseas when granting approval for the specified modification.
  • The GOJ should share information about the progress of the regulatory development in a timely manner in order to provide the opportunities for obtaining feedback from overseas to promote the international harmonization of policies and regulations.
