On Thursday, August 9, the Japanese Ministry of Transport reported that three major automakers - Mazda, Suzuki and Yamaha Motor - falsified testing data for exhaust emissions and fuel economy. This became known after an internal investigations of automakers, carried out by order of the government. In July, the authorities demanded that 23 car and motorcycle manufacturers carry out inspections. Earlier it became known that data on fuel costs and emissions falsified Mitsubishi, Nissan and Subaru. Initially, the checks began after a scandal over the falsification of emission data by the German automaker Volkswagen.

Now, Mazda, Suzuki and Yamaha published their reports on inspections. It was found that companies conducted tests of cars in violation of the rules and in conditions that did not comply with the standards. Suzuki incorrectly tested about half of the 12.8 thousand cars tested since 2012. In the case of Mazda, there are 72 violations with 1,900 testing cases, Yamaha has seven violations for 335 cases. Suzuki and Yamaha have already made statements, apologized for the violations and promised to prevent such mistakes in the future. At the same time, Suzuki said that there are no serious problems with emissions and fuel economy of its cars, and so the company does not plan to recall cars in connection with the current situation.

Once the news was published, Suzuki shares fell by 6%, Yamaha - by 4.6%, and Mazda - by 1.8%. In general, scandals with falsifying testing harm the image of Japanese automotive brands, although, according to the director general of the research company Nakanishi Research Institute Takaki Nakanisi, improperly conducted inspections were not aimed at misleading consumers.
