Mitsubishi Materials Corp. said Monday its president, Akira Takeuchi, will step down to take responsibility for a slew of product quality falsifications at the nonferrous metal group.
Takeuchi, 63, will become chairman without representation rights and will be replaced by Executive Vice President Naoki Ono, 61, pending approval at the general shareholders' meeting on June 22.
"We will change the management to make clear its responsibility over a series of quality issues," Takeuchi said in a statement. "I will instruct and oversee to strengthen the governance of the group as a whole."
Mitsubishi Materials said Friday it had shipped a material used to make concrete with labeling indicating that it was certified as meeting Japan Industrial Standard criteria, when in fact it did not.
On Monday, the company also said it will dismiss the head of its refinery in Kagawa Prefecture, who was responsible for the mislabeled shipment.
The company revealed last year that it had committed product data falsifications at its subsidiaries, which came on the heels of similar scandals at major Japanese manufacturers including Nissan Motor Co., Subaru Corp. and Kobe Steel Ltd.
Last week, Subaru said Yasuyuki Yoshinaga will step down as the carmaker's president and chief executive officer to take responsibility for the scandal.
