Introduction of International Mutual Vehicle Type Approval (IWVTA)
The government made progress, including the incorporation of emission regulations (R154) based on the Worldwide harmonized Light duty driving Test Procedure (WLTP). On the other hand, even after the introduction of the IWVTA system in July 2018, the devices subject to IWVTA are still incomplete to obtain type approval for the whole vehicle. Due to the devices and systems that are not subject to IWVTA, utilization of UN-R0 for mutual recognition of approvals between Japan and the EU has not progressed.
- Japan should work closely with the European Commission to expand the scope of the IWVTA system to cover all the requirements of the Japanese and European vehicle type approval schemes and achieve a complete system for mutual recognition of vehicle type approvals.
