Denso Corp, a critical component supplier to Toyota Motor, reported a 21.5% year-on-year decline in operating profit for the first quarter ended June.

The drop underscores the difficulty Japanese automakers and their suppliers face in offsetting inflationary pressures on raw materials and parts, even as a weaker yen provides some currency tailwinds.

The news adds to a challenging backdrop for Toyota, which recently reported a 49% year-on-year drop in its own fourth-quarter operating profit, largely driven by the impact of U.

The results highlight a structural squeeze on margins within the automotive sector.

While the depreciation of the yen typically boosts the repatriated earnings of Japanese exporters, Denso’s inability to fully capitalize on this advantage suggests that input cost inflation remains a dominant headwind.

This dynamic mirrors broader challenges in the industry, where supply chain costs have proven sticky despite favorable exchange rate movements.
