Japanese Automakers Accelerate Sourcing from China as Local Suppliers Gain Ground with Cost, Efficiency, and Quality

Around May 15, 2024, China's automotive parts industry underwent a significant transformation. Japanese automakers such as Toyota and Nissan began large-scale procurement of Chinese-made components to counter competitive pressures from Chinese brands on both pricing and product performance. Approximately 90% of the components for Toyota’s upcoming bZ3X all-electric SUV—scheduled for launch in 2025—will be sourced from Chinese suppliers. Similarly, Nissan has substantially increased its use of Chinese-sourced parts in its N7 electric sedan. Chinese component manufacturers enjoy cost advantages of 30% to 40% over their Japanese counterparts. In terms of responsiveness, Chinese suppliers typically require only about 10 months on average from order placement to mass production, compared to more than 18 months for Japanese firms. On quality, key Japanese suppliers—including Tokai Rubber Industries (Toyota Boshoku) and Musashi Seimitsu—have publicly acknowledged that the quality gap between Chinese and Japanese components has largely disappeared. As a result, some Japanese auto parts suppliers have continued scaling back operations in China, with several companies already liquidating or shutting down their Chinese plants. Meanwhile, Toyota plans to fully adopt Chinese components in its Southeast Asian production bases starting in 2028 to build a low-cost new energy vehicle platform, aiming to reduce overall vehicle costs by 30%. Although a few Japanese firms, such as Tokai Rubber Industries and Musashi Seimitsu, are attempting to sustain operations by securing orders from Chinese automakers, the broader trend indicates that Chinese component suppliers are rapidly expanding into global markets. Japanese suppliers, in contrast, are shifting focus to regions like India for short-term relief—but this move is unlikely to reverse the changing competitive landscape.
