Mitsubishi Materials Corp., a manufacturer of components used in automobiles and aircraft, said Tuesday it has found more cases of data falsification and misconduct following a probe conducted in the wake of data-rewriting revelations at three of its subsidiaries.
The nonferrous metal and industrial product group is among Japanese manufacturers that have recently been mired in product quality scandals, including product data alteration by Japan's third-largest steel-maker, Kobe Steel Ltd., and inspections by uncertified staff at carmakers Nissan Motor Co. and Subaru Corp.
"I want to offer a deep apology for causing extensive trouble," Mitsubishi Materials President Akira Takeuchi said at a news conference in Tokyo.
