Takeaway
Strong hybrid demand drives revenue but profit performances diverge sharply.
For the fiscal year ended March 2026, major auto parts suppliers achieved record-high revenues, driven by a global resurgence in hybrid vehicle (HEV) demand. However, performance in profitability painted a contrasting picture as some thrived while others stumbled. This report highlights the stark differences between the top-performing companies and those held back by quality scandals and impairment losses.
Industry-Wide Trends
Four key themes shaped the automotive components sector during this fiscal year:
- Resurgence in HEV Popularity: A cooling electric vehicle transition led to a surge in demand for highly fuel-efficient hybrid vehicles.
- Recovery in Automaker Production: Output volumes rebounded at major automakers like Toyota, significantly boosting parts shipments.
- Thorough Operational Streamlining: To offset rising raw material and labor costs, suppliers aggressively improved factory-floor productivity.
- Weak Yen Windfall: The depreciation of the Japanese yen lifted profits for companies with substantial foreign-currency revenues.
These tailwinds helped the majority of suppliers achieve record-high revenues.
Revenue Ranking
Led by DENSO, the top three players boast massive scale with revenues exceeding 4 trillion yen. Driven by a recovery in global vehicle sales, every supplier saw year-on-year revenue expansion.
Operating Profit Ranking
DENSO dominates the pack with operating profit exceeding 500 billion yen. On the other hand, Toyota Ind. fell back significantly with a 38.2% plunge caused by its engine certification scandal.
Winners and Losers
This fiscal year, the clear winner of the group was Toyoda Gosei.
- Revenue reached 1,146.8 billion yen (up 8.2% year-on-year), leading the group in growth.
- Operating profit jumped to 79.6 billion yen (up 32.9% year-on-year).
- Strong demand for safety components like airbags fueled a remarkable V-shaped recovery.
Conversely, the most challenged company and biggest loser of the period was Toyota Ind.
- Revenue grew to 4,369.5 billion yen (up 7% year-on-year).
- Operating profit plunged to 137.0 billion yen (down 38.2% year-on-year).
- Performance was dragged down by massive engine certification scandal-related expenses.
- Following a tender offer, the company is scheduled to delist in June 2026.

Operating Margin Ranking
DENSO and Toyoda Gosei maintained high margins of over 6%. Meanwhile, Toyota Ind. recorded the lowest margin at 3.1% due to the heavy burden of certification scandal expenses.
Revenue Growth YoY
All suppliers achieved positive revenue growth supported by a recovery in production among primary clients. Toyoda Gosei posted the highest growth rate at 8.2%, boosted by its acquisition of Ashimori Industry.
Net Income Growth YoY
Aisin and Toyoda Gosei stood out with strong growth in net income. Conversely, Koito saw its net income plunge by 64.2% due to impairment charges in its Chinese operations and LiDAR business.
Strategic Moves and Company Comparisons
Suppliers are adopting distinct strategies to secure their long-term competitiveness:
- DENSO: DENSO achieved record revenue of 7,540.0 billion yen (up 5.3% year-on-year), but expects operating profit to decline by 9.5% next fiscal year as it prioritizes future investments.
- Aisin: Revenue reached 5,117.8 billion yen (up 4.5% year-on-year). The company demonstrated its commitment to capital efficiency by authorizing a share buyback of up to 100 billion yen.
- Koito: Operating profit recovered to 51.4 billion yen (up 14.6% year-on-year). However, impairment charges related to its LiDAR business and other segments dragged net income down 64.2% to 16.5 billion yen.
Shared Industry Risks
Despite solid top-line performances, all five suppliers face persistent headwinds:
- Rising R&D Expenses: Heavy investments in next-generation technologies continue to squeeze profit margins.
- Global Tariff Risks: Import duties in key markets like the U.S. threaten to raise export costs.
- Fierce Competition in China: The rapid rise of local Chinese manufacturers risks eroding profitability.
- Escalating Recruitment Costs: Labor shortages continue to drive up payroll and recruitment expenses.
Implications for Job Seekers and Career Changers
For prospective employees and career changers, the auto parts sector presents compelling opportunities:
- Pioneering Cutting-Edge Tech: Industry leaders like DENSO and Aisin are at the forefront of autonomous driving and next-generation mobility.
- Focus on Business Agility: Companies like Toyoda Gosei that actively restructure and concentrate resources stand out as highly resilient.
- Keep an Eye on Realignment: With group restructuring underway, understanding each company's next strategic move is vital.
