The admissions are the latest in a string of scandals involving data falsification and testing standard breaches in Japan's key auto sector.
Suzuki, Mazda and Yamaha said they would take preventive steps, such as changing inspection devices so their staff can not rewrite the data.
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 USA diesel cars to cheat exhaust emissions tests, and that as many as 11 million vehicles could have similar software installed worldwide.
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.
Mazda Motor Corp. and Yamaha Motor Co. have admitted using falsified emissions data to inspect their new vehicles in a product quality scandal in Japan's auto industry. In Yamaha's case, irregularities were found in 2 percent of inspections, or just a handful of vehicles.
Yamaha also confirmed it carried out inappropriate testing and apologized. The transport ministry will change its ministerial ordinance to request automakers save test results of manufactured vehicles and take measures to prevent adjustment of results.
Suzuki and Yamaha shares fell 6 and 5 percent, respectively, and Mazda shares were down 1 percent, underperforming a steady benchmark Nikkei average.
None of the automakers reportedly found problems in their vehicles' correct emissions and fuel economy performance that warranted a recall.
