Mazda Motor and Yamaha Motor have received approval from the Japanese government to resume shipments of three vehicle models previously halted due to improper testing concerns. The Ministry of Land, Infrastructure, Transport and Tourism announced Friday that the suspension on Mazda’s Roadster RF, Mazda2, and Yamaha’s YZF-R1 motorcycle has been lifted after verifying that there are no safety issues.
Mazda plans to restart deliveries of the affected models on Monday, with production of these vehicles set to resume in mid-July. Yamaha aims to begin shipments of its motorcycle by early July.
The transport ministry’s investigation, triggered by compliance irregularities at Daihatsu Motor and Toyota Industries, involved several Japanese vehicle and auto parts manufacturers. The inquiry uncovered issues with 38 models from five manufacturers, including Toyota Motor, Honda Motor, and Suzuki Motor. However, safety standards were met for all models except those from Toyota.
Following on-site inspections and finding no intentional wrongdoing, the ministry decided not to revoke certifications but mandated Mazda, Yamaha, and Honda to implement preventive measures against future irregularities and report their progress semiannually.
Toyota’s internal investigation continues, with a resolution expected by July. Currently, shipments of the Yaris Cross, Corolla Fielder, and Corolla Axio remain suspended.
This development comes amid broader scrutiny within Japan’s automotive industry, with the transport ministry confirming that most manufacturers, except Toyota, have now complied with safety standards post-investigation.
