Seven major Japanese automakers reported combined tariff-related costs totaling 2.1 trillion yen for the April–December 2025 period, according to consolidated earnings reports released Thursday. The expenses are tied to higher U.S. import tariffs introduced during that time.
The financial impact varied across companies but was significant throughout the industry. Toyota Motor Corp. absorbed the largest share, reporting tariff-related costs of approximately 1.2 trillion yen. Honda Motor Co. recorded costs of 289.8 billion yen, while Nissan Motor Co. reported 232 billion yen. Subaru Corp. disclosed costs totaling 216.6 billion yen.
The remaining automakers, including Mazda Motor Corp. and Mitsubishi Motors Corp., also faced notable financial pressure linked to tariff expenses during the first nine months of fiscal 2025.
Profit Impact Across the Sector
The additional costs contributed to declining profitability across the sector. Nissan, Mazda, and Mitsubishi Motors each reported net losses for the period. Nissan posted a net loss of 250.2 billion yen, while Mazda recorded a net loss of 14.7 billion yen and Mitsubishi Motors reported a net loss of 4.4 billion yen.
Other automakers remained profitable but experienced year-on-year declines in net income, reflecting the broader financial strain caused by higher trade duties and market conditions.
Cost-Cutting Measures
Automakers implemented cost-reduction strategies, including efforts to lower vehicle manufacturing expenses, to help offset the increased tariff burden. However, company disclosures indicate that these measures only partially compensated for the higher import duties.
Industry analysts note that sustained tariff levels can affect pricing strategies, production planning, and global supply chain decisions. Japanese manufacturers maintain significant exposure to the U.S. market, one of their largest overseas destinations, making changes in trade policy particularly impactful.
The cumulative 2.1 trillion yen cost underscores the scale of the financial effect on Japan’s automotive sector during fiscal 2025 and highlights the continued importance of monitoring trade policy developments for globally integrated industries.
