Japanese automakers Suzuki Motor Corp., Mazda Motor Corp. and Yamaha Motor Co. have admitted using falsified emissions data to inspect their new vehicles after the government ordered the industry to review its procedures.

Japan's Mazda, Suzuki and Yamaha have admitted to conducting improper fuel economy and emissions tests on their vehicles in Japan, in revelations which pile further misery on Japan's beleaguered manufacturing sector.

The conduct of automakers globally has come under intense scrutiny after Germany's Volkswagen AG (VOWG_p.DE) admitted in 2015 to installing secret software in hundreds of thousands of US diesel cars to cheat exhaust emissions tests, and that as many as 11 million vehicles could have similar software installed worldwide.

Mazda's inquiry, while acknowledging 72 cases out of 1,472 vehicles examined were handled inappropriately, says its investigation found "no improper adjustment or falsification of test data".

The company's emissions testing system "was not set up to automatically invalidate results when a speed trace error occurred", it explained, while the level of deviation permitted under the test was at the discretion of each individual inspector.

Suzuki, Mazda and Yamaha are implicated, although with different levels of severity.

"It is a significant fact that such a large number of our products were improperly processed, and we take it seriously", Suzuki said during a press conference.

The three companies said they certified products that tested unsuccessfully.

At Mazda, of 1,875 cars subject to the sampling inspection, improper inspections were discovered in almost 4 percent since November 2014.

Suzuki tumbled 6.04 percent to 6,944 yen, Mazda sank 1.30 percent to 1,327 yen and Yamaha Motor dived 4.63 percent to 2,820 yen.

None of the automakers reportedly found problems in their vehicles' correct emissions and fuel economy performance that warranted a recall.

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