Japan’s Mitsubishi Materials Corp. said Thursday it has found additional cases of product data falsification involving three of its subsidiaries, two of which were newly found to have engaged in the irregularities.

The three firms are Tokyo-based Mitsubishi Aluminum Co., its aluminum-processing unit, Tachibana Metal Co., based in Osaka, western Japan, and auto parts maker Diamet Corp., based in the city of Niigata, central Japan.

Nearly 500 client companies were supplied with products that were affected by the newly found manipulation of product quality data.

Now that five Mitsubishi Materials units have been found to be engaged in data falsification, Mitsubishi Materials President Akira Takeuchi told a press conference, “We offer a deep apology for the inconvenience to parties concerned.”

According to Thursday’s announcement, a Mitsubishi Aluminum factory in Susono, Shizuoka Prefecture, central Japan, and a Tachibana Metal plant in Yoro in the central prefecture of Gifu manipulated quality data on extruded aluminum products.

In addition, they carried out product inspections that did not meet the requirements of the Japanese Industrial Standards.

Affected clients totaled 115 firms for Mitsubishi Aluminum and 307 companies for Tachibana Metal. No safety problems have been raised.

Diamet shipped products with falsified inspection data, manufactured in its main factory, to 73 companies. The safety of the shipped products is currently under investigation, Diamet said.

The additional wrongdoing was revealed by an inspection Mitsubishi Materials started late last year in the wake of the initial revelations of data fabrication.

Mitsubishi Materials last year said Mitsubishi Cable Industries Ltd., Mitsubishi Shindoh Co. and Mitsubishi Aluminum had shipped products after falsifying inspection data to appear as if they satisfied quality standards promised to clients.

An interim report released late last year by an investigation committee set up by Mitsubishi Materials showed that there were guidelines used by employees to share procedures for data falsification.

Mitsubishi Materials was scheduled to release a final report later this month, but the release was postponed until at least March due to the newly found data falsification.
