Trump Policies Deliver Heavy Blow to Japanese Automakers

[Policy Impact] Frequent policy shifts by the Trump administration have caused massive losses for Japanese automakers.

Key Figures: Cumulative Losses Could Exceed $40 Billion

$28 billion represents the total cost borne by Japan's top six automakers (Toyota, Honda, Nissan, Mazda, Subaru, and Mitsubishi) through March 2026 due to U.S. tariffs, elimination of electric vehicle tax credits, and relaxed emissions regulations. An additional $11.98 billion in tariff expenses is expected this fiscal year, pushing cumulative losses beyond $40 billion by March 2027.

Strategic Foundation: North American Integration Model Under Pressure

Japanese automakers have long relied on integrated production capacity and supply chains across the U.S., Mexico, and Canada to build an efficient North American operational system. Sudden policy changes are forcing companies to accelerate restructuring of their production footprints—an effort that incurs high costs and cannot be absorbed quickly.
