As of November 10, seven prominent Japanese automakers have unveiled their consolidated financial statements for the first half of the 2025 fiscal year, spanning from April to September. These companies were severely impacted by the substantial surge in U.S. import tariffs, which took effect on April 3 (though there was a subsequent reduction on September 16), coupled with the appreciation of the yen's exchange rate. Consequently, the cumulative operating profit loss for these seven firms amounted to roughly 1.5 trillion yen. Out of this total, approximately 700 billion yen can be attributed to the adverse effects of exchange rate fluctuations. This situation has even led to net losses for Nissan, Mazda, and Mitsubishi.

During the period from April to September, the combined net profit of the seven automakers stood at approximately 2.1 trillion yen, marking a nearly 30% year - on - year decrease. Looking ahead to the 2025 fiscal year, it is anticipated that U.S. tariffs will exert a profit - squeezing pressure of about 2.5 trillion yen on these companies. Among them, Mazda and Subaru are expected to bear the brunt of this impact.

In reaction to the evolving market conditions, Mitsubishi is contemplating strengthening its North American production collaboration with Nissan. Meanwhile, Mazda has formulated plans to expand the production capacity of its joint - venture factory.
