Takeshi Sugiyama has resigned as Mitsubishi Electric Corp's president and CEO to take responsibility for years of cheating in train equipment inspections.
Kei Uruma, formerly the Senior Vice President, has replaced Sugiyama.
Mitsubishi Electric said that under Uruma, it will ascertain the root causes of the misconduct, restore shareholders' trust, and reform its corporate culture.
Sugiyama said that cheating during inspections of air conditioners and compressors for train use was "organizational" and may have been occurring since 1985.
About 84,600 air conditioners for trains were delivered between 1985 and 2020 to about 80 companies, with 15,800 units shipped to 15 countries, including the US, the UK, and Germany.
Around 1,500 air compressors for controlling train doors and brakes were all shipped in Japan.
Mitsubishi Electric's domestic customers include and Central Japan Railway Co., East Japan Railway Co., and West Japan Railway Co.
Last year, Mitsubishi Electric delivered automotive radio receivers to the EU that did not meet local standards, while a subsidiary shipped substandard rubber products in 2018.
