Mitsubishi Materials Adds to Japan Inc.’s Quality Problems
TOKYO — The president of Mitsubishi Materials apologized on Friday for the latest breach of quality standards to rattle corporate Japan after
the company said it had falsified inspection data for components it sold to manufacturers of cars, aircraft and industrial equipment.
Mitsubishi said that when its quality inspections revealed
that products fell short of those standards, it sometimes faked inspection data to make it appear as though the products met them.
The company said managers at one of three subsidiaries where the deception occurred became aware of the data falsification in February after an internal inspection,
but they did not report the issue to superiors at the parent company until October.
