Toyota urges Japan’s carmakers to unite against growing Chinese competition

Toyota calls for industry cooperation

Toyota (NYSE: TM) has proposed closer cooperation among Japan’s seven major automakers to improve competitiveness against fast-growing Chinese rivals. Koji Sato, Toyota’s Chief Industry Officer and chairman of the Japan Automobile Manufacturers Association, wants companies to share more manufacturing standards. The proposal focuses on reducing costs while allowing each brand to keep its own identity.

Koji Sato does not support mergers or shared vehicle designs between competing brands. Instead, the plan encourages common standards for parts and production processes that customers rarely notice. The goal is to help Toyota, Honda, Nissan, Mazda, Subaru, Mitsubishi, and Suzuki invest more resources in batteries, software, and future vehicle technologies.

Toyota wants common vehicle parts

Toyota wants Japan’s automakers to standardize common components such as steel grades, plastics, and wiring harnesses. These parts are essential to manufacturing but are usually invisible to customers. Sharing specifications would reduce unnecessary engineering differences across brands.

Suppliers currently produce about 70,000 variations of wiring harnesses for Japanese automakers. Koji Sato said standardizing wiring harnesses alone could improve productivity by 10 times. Lower complexity would also simplify manufacturing and reduce costs throughout the supply chain.

Toyota wants competition to change

Toyota believes automakers should continue competing where customers notice differences between vehicles. Styling, driving performance, software, battery technology, and customer features would remain unique for every brand. The proposal focuses only on cooperation in areas that do not affect brand identity.

Koji Sato described the strategy as creating areas of cooperation while preserving areas of competition. Engineers could spend less time solving the same manufacturing problems repeatedly. More investment could then move toward technologies that improve future vehicles and global competitiveness.

Chinese brands increase pressure

Chinese automakers are expanding rapidly across Europe, China, Southeast Asia, and Australia. Their growth has increased pressure on Japanese manufacturers that were once dominant in many international markets. Competition has become especially intense in electric vehicles and software-focused cars.

Chinese brands collectively outsold Japanese automakers in Europe for the first time in May. Five major Chinese automakers sold 138,410 vehicles, while 6 major Japanese automakers sold 130,424 vehicles during the month. The shift highlighted how quickly global competition is changing for Japan’s auto industry.

China becomes a difficult market

Toyota, Honda, and Nissan all recorded double-digit sales declines in China during the first half of the year. Toyota sales fell 17.1%, Nissan declined 15%, and Honda dropped 34.7%. Honda also extended its streak of monthly year-over-year sales declines to 29 consecutive months.

Chinese companies have strengthened their position by expanding their portfolios of electric and smart vehicle technologies. New energy vehicles accounted for 49.6% of China’s total new vehicle sales in the first half of the year. The market continues shifting toward electric models at a rapid pace.

Toyota wants more innovation

Toyota believes reducing duplicated engineering work would free resources for future technologies. Money saved through simpler manufacturing could support battery development, software, automation, and advanced driver assistance systems. Those areas have become increasingly important for global competition.

Japanese automakers have traditionally earned strong reputations for quality and reliability. Many competitors, however, moved faster in electric vehicles and software-defined vehicle development. Toyota believes greater cooperation could help close those technology gaps more efficiently.

Smaller brands could benefit most

Toyota’s proposal could provide significant advantages for smaller Japanese automakers. Companies such as Mazda and Mitsubishi generally have fewer financial resources and lower purchasing power than Toyota. Shared standards could reduce development costs across multiple vehicle programs.

Lower spending on common components would allow manufacturers to invest more in batteries, software, automation, and faster product development. The proposal is designed to improve competitiveness while allowing each company to maintain its own brand identity.

Toyota already works with rivals

Toyota has a long history of working with other automakers on selected projects. The GR86 was developed with Subaru, while the Supra shares major engineering with BMW. Toyota has also partnered with Suzuki and Mazda on multiple vehicle programs.

Koji Sato believes broader cooperation can build on those successful partnerships. Future collaboration would focus more on manufacturing standards than complete vehicle development. That approach would preserve competition while reducing duplicated work across the industry.

Suppliers could gain efficiency

Suppliers currently manufacture countless versions of similar materials and components for different automakers. Separate specifications increase production complexity and complicate logistics. Common standards would simplify manufacturing throughout the supply chain.

Steel grades, plastics, and wiring harnesses are among the first components under consideration. Simpler production could reduce procurement costs while improving manufacturing efficiency. Suppliers would also spend less time managing thousands of different product specifications.

Europe offers a warning

European automakers are facing significant pressure from expanding Chinese vehicle manufacturers. Volkswagen recently outlined plans to reduce its vehicle lineup by up to 50%. Reports also indicated that as many as 100,000 jobs could be affected by restructuring.

Koji Sato believes greater cooperation could improve efficiency and strengthen Japan’s automakers’ global competitiveness. The proposal reflects increasing concern about long-term changes in the global automotive industry.

The plan faces challenges

Creating shared standards across seven competing automakers will require broad agreement. Every company operates different factories, vehicle platforms, suppliers, and development schedules. Reaching common decisions may take considerable time.

Suppliers would also need to support the new manufacturing standards. Some automakers may disagree about which specifications should become industry standards. Those practical challenges could slow implementation even if companies support the overall strategy.

Japan sees a major transition

Koji Sato believes Japan’s auto industry has entered a period of major transformation. Electric vehicles, software, automation, and changing consumer demand are reshaping global competition. Traditional business models are facing increasing pressure from new competitors.

The Japan Automobile Manufacturers Association is also working on logistics improvements, talent recruitment, autonomous driving infrastructure, and recycling initiatives. These efforts aim to strengthen the industry’s long-term competitiveness. Cooperation on common components is one part of that broader strategy.

Toyota sees cooperation as a strategy

Toyota believes sharing common manufacturing standards could strengthen Japan’s automotive industry without reducing competition between brands. Customers would continue seeing different vehicle designs, features, and driving experiences across manufacturers. Cooperation would remain focused on behind-the-scenes components and production methods.

The proposal reflects how rapidly the global automotive market is changing. If Japan’s automakers agree on common standards, they could reallocate more resources to batteries, software, and future mobility technologies. That strategy could help the industry compete more effectively against fast-growing global rivals.
