Japan’s car industry explores collaboration to cut costs amid rising global competitiveness

Koji Sato, Toyota’s chief industry officer and chairman of Japan’s main carmakers’ lobby, is urging an industry long defined by rivalry and engineering independence to cooperate far more closely on parts and production standards. His pitch is not that Japan’s manufacturers should build identical cars, but that they should stop reinventing the same invisible components, from wiring harnesses and hoses to fasteners and certain plastics.

The logic is straightforward. By st...

andardising commodity parts and sharing more manufacturing know-how, Sato argues, Japanese groups could trim costs and redirect cash towards the technologies now deciding the sector’s future: batteries, electric drivetrains, software and driver-assistance systems. That matters because the competitive pressure has sharpened. Chinese manufacturers have been pushing down development times and costs through tightly integrated supply chains, while Tesla has taken a similarly ruthless approach to simplification in design and production.

Sato’s argument echoes an old refrain from the late Sergio Marchionne, who spent years warning that carmakers were wasting vast sums duplicating work on parts customers never see. His view was that companies should compete on what buyers notice and collaborate on the rest. At the time, many executives treated that as a theoretical provocation. In today’s market, it looks far closer to a survival strategy.

For Japan’s car industry, the challenge is cultural as much as technical. Toyota, Honda, Nissan, Mazda and Subaru have traditionally guarded their own platforms, architectures and component designs, a model that helped fuel innovation during the industry’s strongest decades. But with electrification, software and autonomy all demanding heavy investment at once, duplication has become harder to justify.

The proposal does not amount to consolidation, and it is not a call to blur brands or merge companies. It is, rather, an attempt to preserve the strengths of Japan’s automotive base by reducing the expensive effort spent on undifferentiated parts. If the country’s carmakers can agree on that distinction, they may yet find in cooperation a way to compete more effectively with the new industrial order being set by China and Tesla.
