Toyota Motor Corp. warned it now expects a ¥1.4 trillion ($9.5 billion) blow to operating profit from higher U.S. import levies and trimmed its full-year earnings guidance by 16 % to ¥3.2 trillion for the fiscal year ending March 2026. The world’s largest automaker said first-quarter net profit fell 37 % to ¥841.3 billion as the 25 % tariff introduced by President Donald Trump in April, a stronger yen and rising material costs eroded margins. The hit was most acute in North America, where Toyota swung to an operating loss of ¥63.6 billion despite a 7 % rise in global vehicle sales. Management said it would counter the tariff pressure through cost reductions, supply-chain adjustments and new investment, but cautioned that the timing of a promised reduction in the levy to 15 % under a July U.S.–Japan accord remains uncertain. Honda Motor Co. offered a contrasting picture. Although the company’s April–June operating profit halved, it lifted its full-year outlook, citing resilient demand and cost controls. Honda also lowered its estimate of tariff damage by roughly a third to ¥450 billion. Electronics maker Sony likewise nudged its guidance higher, underscoring how the new trade regime is splitting corporate fortunes within Japan Inc. Tokyo has urged Washington to implement the agreed tariff cut swiftly amid wider concerns that additional duties on semiconductors and other goods could further cloud the outlook. With Toyota alone facing the biggest single-company tariff bill disclosed to date, automakers on both sides of the Pacific are reassessing pricing, production and investment plans in the world’s second-largest car market.
