Denso and Mitsubishi Electric say they are “fully co-operating” with investigators from the Japan Fair Trade Commission (JFTC), which visited the companies today (20 July).

The automotive suppliers are being investigaged by the JFTC in relation to Japan’s anti-monopoly act regarding sales of certain automotive components.

“I can confirm that this morning in Kariya, at our headquarters, we had a visit – obviously we are fully co-operating with the investigation,” a Denso spokesman in Amsterdam told just-auto. “We have no further comment at the moment.

“The next stage is we follow directions from the Japan Fair Trade Commission at what we need to provide in order to co-operate with their investigation.”

Denso added that as well as the Kariya, Aichi location, other sales branches in Japan were also being investigated.

Mitsubishi also confirmed it was being looked at by the JFTC as a result of what it described as “suspected infractions” of the anti-monopoly act regarding sales of certain automotive equipment.

Searches by the JFTC took place at Mitsubishi’s company headquarters in Tokyo, its Chubu branch in Aichi prefecture and several sales offices.

Furthermore, the Northville office of Mitsubishi Electric Automotive America in Northville, Michigan, was searched by the Federal Bureau of Investigation on 19 July in relation to an inquiry regarding automotive equipment.

Mitsubishi Electric said it was “fully cooperating” with the investigations.

Reports indicate up to seven large automotive components manufacturers are being investigated, although this has not yet been confirmed.

Calls to the Japan Fair Trade Commission in Tokyo did not immediately elicit a response.
