Japan's transport ministry said Thursday the three automakers admitted conducting improper inspections after 23 Japanese auto and motorbike manufacturers were ordered to examine their inspection procedures in July following similar mishandlings being found at Nissan Motor Co. and Subaru their fuel economy data at final product quality checks.

The results came to light after the Japanese government had ordered the automakers to check their operations after revelations of improper testing at Subaru and Nissan past year. According to Ministry of Land, Infrastructure and Transport of Japan, Suzuki, along with Mazda and Toyota have accepted to having cheated on the emissions tests and submitted a report of samples of manufactured vehicles selected during the quality assurance process.

The report is the latest episode in a growing list of data falsifications that have tarnished the image of Japan's manufacturing industry, known for its high-quality and efficient production.

The automakers examined tests they had conducted over different periods of time, and in Suzuki's case they stretched back to 2012.

The companies admitted incomplete emissions tests were done on some of its vehicles, but their officials certified the results as though the tests had been administered fully.

"I deeply apologize and will lead efforts to prevent a recurrence", Chief Executive Toshihiro Suzuki told a news conference.

The company, however, said it did not find any significant problems with actual emissions and fuel economy performance and therefore planned no recalls.

In a similar sample, Mazda uncovered inappropriate testing on 72 vehicles out of 1,875 units since 2014.

Following the emergence of the news, stock prices in Mazda and Suzuki fell by up to 5 per cent.

Kobe Steel, Mitsubishi Materials Corp and Toray Industries - all key suppliers of motor parts to global manufacturers - admitted to product data fabrication past year.

Numerous automakers, already hit by lackluster sales, have also been under pressure from U.S. President Donald Trump's proposed tariffs on imported vehicles.
