Is DENSO owned by Toyota?
Yes, DENSO is a key member of the Toyota Group, but it is not owned by Toyota. DENSO operates as an independent, publicly traded company with Toyota acting as its largest shareholder and a major customer.
What is DENSO?
DENSO Corporation is a global supplier of automotive components, designing and manufacturing systems for engines, electronics, safety, and mobility technologies. Based in Aichi Prefecture, Japan, it is publicly listed on the Tokyo Stock Exchange under the ticker 6902 and serves automakers around the world.
Key ownership and governance facts include:
- DENSO is an independent company with its own board, finances, and corporate governance.
- It is publicly traded on the Tokyo Stock Exchange under the ticker 6902.
- Toyota Motor Corporation holds a substantial minority stake, making it the largest shareholder in DENSO.
- The two companies are part of the broader Toyota Group, sharing business goals but maintaining separate management.
- DENSO serves multiple automakers beyond Toyota, including other global manufacturers.
In short, DENSO is not a Toyota subsidiary; it operates independently while maintaining a close supply-relationship with Toyota.
Toyota's role and the cross-shareholding reality
The relationship between Toyota and DENSO is characterized by investment ties and collaborative supply chains, rather than a simple parent-subsidiary structure. Toyota is the largest shareholder in DENSO, and both companies coordinate on technology and production planning while preserving separate governance.
Key points about Toyota's stake and governance:
- Toyota holds a substantial minority stake in DENSO, making it the largest shareholder.
- Despite the stake, DENSO remains a separate, publicly traded company with its own board of directors.
- There are cross-shareholdings and collaboration within the Toyota Group, but DENSO is not fully owned by Toyota.
- The relationship helps align supply chain strategy and joint product development, while preserving DENSO's independence.
Thus, while Toyota is a major investor, DENSO's ownership is not exclusive to Toyota.
Cross-shareholding within the Toyota Group
Historically, Toyota and DENSO have maintained cross-shareholdings as part of the broader Toyota Circle. In recent years, efforts to improve governance and capital efficiency have moderated these holdings, though the linkage remains significant.
Independent governance and public listing
DENSO operates with its own governance framework, independent auditors, and a board chosen by DENSO's shareholders. This structure enables DENSO to serve multiple automakers while benefiting from the scale and technology access available through the Toyota Group.
What this means for stakeholders
For investors, suppliers, and customers, the Toyota–DENSO relationship signals stability and coordinated technology development, while preserving DENSO's market competitiveness and governance independence.
Impact on investors
As Toyota remains the largest shareholder, investors in DENSO should monitor how stake levels influence strategic decisions, dividend policy, and governance transparency.
Impact on customers and suppliers
For automakers and suppliers, DENSO's independence means competitive sourcing and broad collaboration opportunities beyond Toyota's ecosystem, while benefiting from the scale and reliability of the Toyota Group relationship.
Summary
Bottom line: DENSO is not owned by Toyota. It is an independent, publicly traded company that sits within the Toyota Group, with Toyota as its largest stakeholder and a major customer. DENSO operates with its own governance and serves a global roster of automakers, while collaborating closely with Toyota on technology and supply chain initiatives. This arrangement provides stability and competitive opportunities for both parties and for the broader automotive industry.
Does Toyota still own DENSO?
After becoming independent from Toyota Motor, the company was founded as Nippon Denso Co. Ltd. (日本電装株式会社, Nippon Densō Kabushiki-Gaisha) in 1949. About 25% of the company is owned by Toyota.
Is DENSO made in China?
All DENSO Spark Plugs are manufactured in Japan, Indonesia, China and USA. If a part claims to be a DENSO component but has been manufactured outside of these areas, then it is not genuine. Counterfeit spark plugs may also have subtle differences in the logo placement.

Does Toyota use NGK or DENSO?
Toyota uses both NGK and Denso spark plugs, depending on the specific vehicle model and engine. While many sources state that Denso is the most common original equipment manufacturer (OEM) supplier for Toyota, some Toyota and Lexus models come with NGK as the OEM part. When replacing spark plugs, it is best to check the owner's manual for the recommended manufacturer and specification, or to look at the spark plugs already in the engine.
- Denso: Denso is frequently the OEM supplier for many Toyota engines, with its plugs often found as the factory-installed option.
- NGK: Some Toyota and Lexus models are equipped with NGK spark plugs from the factory, and they are also a popular and high-quality aftermarket alternative.
- Compatibility: Both brands are reputable, and many aftermarket parts stores will carry both as options. However, for the most accurate replacement, it is crucial to match the specific plug's heat range and other specifications to what the manufacturer recommends for your vehicle.
