Mitsubishi Materials, a Japanese manufacturer of construction materials, apologized on Friday for the data falsification scandal involving some of its brass, aluminum and copper products, which has affected 274 companies worldwide.

At a press conference in Tokyo, Mitsubishi Materials Corp President Akira Takeuchi said the company wanted to resolve the problem as soon as possible.

He added that Mitsubishi was verifying the safety of the products with the affected companies and would do everything needed to ensure the falsification would not happen again.

Three of the company's subsidiaries falsified inspection data about their products to show that they met customer specifications.

The falsifications affected data such as the hardness and tensile strength of brass and copper parts used in the automobile and electronics industries as well as sealing materials, especially rubber and aluminum.

The conglomerate admitted that, between April 2015 and Sept. 2017, its subsidiary, Mitsubishi Cable Industries, sold 270 million units (20 percent of the total volume sold) of sealing products, used to prevent oil, water or air leaks, to 229 companies.

Meanwhile, another subsidiary, Mitsubishi Shindoh, also delivered products with falsified data, between Oct. 2016 and Oct. 2017, including 879 tons of brass, various alloys, and copper to 29 companies, 0.6 percent of the total volume sold.

Another 16 clients received an undisclosed quantity of aluminum from Mitsubishi Aluminium, a matter which Takeuchi downplayed by saying the issue had already been resolved with the affected companies, with whom they have confirmed the safety of all affected products.

Mitsubishi Materials has admitted that it had been aware of the falsification since February. The company defended the delay in disclosing the falsification details by pointing to the time it took to analyze and verify the irregularities.

At a press conference on Friday, Transport Minister Keiichi Ishii called the scandal involving Mitsubishi Materials "extremely regrettable."
