On Friday Japan’s Ministry of Transportation said that it had found discrepancies between lab and real-world emissions measurements for diesel vehicles from Toyota, Nissan, and Mitsubishi. However, the ministry said that it had not found any illegal software on the vehicles and that the automakers had not violated any of Japan’s regulations.

According to the Wall Street Journal, Toyota’s Hiace van and the Land Cruiser Prado sport-utility vehicle, as well as Nissan’s X-Trail SUV and Mitsubishi’s Delica D:5 all emitted between four and 10 times the amount of nitrogen oxide (NOx) that is allowed in Japan's real-world driving tests.

Japan has been testing vehicles sold in the country after the US Environmental Protection Agency (EPA) discovered that diesel vehicles sold by Volkswagen Group were emitting many times the legal limit of NOx due to illegal software placed on the cars that let them cheat on lab testing conducted by regulators. The ensuing scandal has sent Volkswagen’s stock into a nosedive and has potentially put the company on the hook for tens of billions of dollars in fines.
