In December 2024, Japan’s two automotive giants, Honda and Nissan, announced merger talks and signed a memorandum of understanding with Mitsubishi Motors. According to the initial plan, Honda and Nissan were to jointly establish a holding company in 2026, aiming to create a world-class mobility enterprise with annual sales exceeding 30 trillion yen and annual operating profits surpassing 3 trillion yen. However, just over a month later, the merger plan was abruptly scrapped, making it one of the shortest-lived alliances in history.

This sudden termination reflects the strategic anxiety of Japanese automakers amid the waves of electrification and intelligent vehicle technology. In the face of dramatic changes in the global automotive industry, why did Honda, Nissan, and Mitsubishi fail to join forces for a breakthrough?

Disputes Over Control and Technology Roadmaps

One of the core issues behind the breakdown was the dispute over control. Honda’s market capitalization is about four times that of Nissan, giving it a financial and business advantage. As per the initial agreement, Honda was to take the lead in the new company and nominate its president. However, as negotiations progressed, Honda sought to acquire 100% of Nissan’s shares for full control, while Nissan insisted on maintaining an equal position in the new company. Ultimately, this disagreement led to the collapse of the talks. Industry insiders commented, “Nissan has its pride, Honda is too arrogant, and the only outcome was to abandon integration.”

Beyond control issues, the two companies also had irreconcilable differences in their technological strategies. Nissan was keen to accelerate the development of its e-Power hybrid technology while betting heavily on pure electric vehicles. Honda, on the other hand, focused on hydrogen energy, having launched the Clarity fuel cell vehicle and collaborated with General Motors on next-generation hydrogen power systems. During negotiations, Nissan pushed to eliminate the hydrogen energy project, while Honda countered by arguing that the risks of an all-electric strategy were too high. These conflicting technological directions made it difficult for the two companies to establish a unified development strategy.

Additionally, differences in corporate culture and management styles created further obstacles. Honda is known for its strong engineering culture, emphasizing independent research and innovation, whereas Nissan, having been part of the Renault-Nissan-Mitsubishi alliance for years, had adopted a more internationalized management approach. These factors further complicated the integration process.

In recent years, the global automotive industry has undergone profound changes, with electrification and intelligent technologies becoming irreversible trends. Against this backdrop, more and more automakers have chosen to unite, aiming to pool resources and share costs and risks. However, history has shown that not all mergers succeed—for example, the 2007 Daimler-Benz and Chrysler merger ultimately ended in separation.

Despite the collapse of the Honda-Nissan merger, both companies have stated that they will continue to collaborate in smart and electric vehicle technology to accelerate innovation and commercialization. Honda plans to increase the share of electric vehicles in its total sales to 40% by 2030, invest more in battery technology, and work with General Motors to develop a new electric vehicle platform to reduce R&D costs. Nissan, on the other hand, is pushing forward with its “Nissan NEXT” transformation plan, focusing on enhancing its EV competitiveness and improving battery recycling and reuse technologies to boost sustainability. Meanwhile, Mitsubishi Motors remains committed to the plug-in hybrid market and plans to expand its presence in Southeast Asia.

The rapid rise of Tesla and the explosive growth of Chinese EV manufacturers have demonstrated that the global automotive market is accelerating its transformation. Whether Japanese automakers can break through in this revolution depends on their strategic execution and market adaptability. Although the Honda-Nissan merger fell through, future cooperation in key technological fields may still yield breakthroughs.

To stay competitive in the global EV race, Japanese automakers may need to decisively adjust their strategies, break free from traditional thinking, and adopt more open and flexible collaboration models to embrace industry changes. After all, in this automotive revolution, hesitation and indecision could be the greatest risks.
