This week’s news that Carlos Ghosn is stepping down as CEO of Nissan will send a tremor through the Daichi Tamachi tower block in the Minato-ku area of Tokyo.
Floor five of that sober office is the front door into Mitsubishi Motors, now part of the Renault-Nissan Alliance, which took control in October last year for £1.7 billion. Now the alliance's chief, Ghosn, is about to turn his beady eye on its new partner.
So far, Nissan has kept quiet about its plans for Mitsubishi, referring to “synergies to enhance profit margins” and it is true that Mitsubishi doesn’t need slash-and-burn, largely because the past decade has been filled with restructuring.
The global factory network, for example, which once included European, US and Australian plants, has been slimmed to three assembly plants in Japan – Ozazaki, Mizushima, Sakagura – plus Thailand and Philippines pick-up and commercial plants.
Engines and transmissions are sourced from two powertrain plants, one in Kyoto and the other in Shiga, plus an Asian site for the pick-ups.
And five R&D centres support production with design and development.
