DENSO Wave is a subsidiary that produces automatic identification products (barcode readers and related products), industrial robots, and programmable logic controllers.{{cite web|title=Corporate Outline|url=https://www.denso-wave.com/en/about/outline/|access-date=2020-08-05|website=Denso Wave Inc.}} They are noted for creating the two-dimensional QR code, are a member of the Japan Robot Association, and support the ORiN standard.

In 1992 Masahiro Hara, an engineer in the Research & Development department, was tasked with developing a new 2D code system to streamline the tracking of components used in the automotive industry. Traditional barcodes had limitations, including their low data capacity and sensitivity to damage, such as oil stains, which caused scanning errors. To overcome these challenges, Hara began researching and, in 1994, invented the QR code.

Inspired by the black-and-white patterns of the Japanese strategy game Go, the QR code can store 200 times more characters than a standard barcode and remains readable even if 30% of its surface is damaged, thanks to its error correction mechanism. Originally referred to as the "ND code" (for Nippon Denso), it was later renamed QR code, short for Quick Response, to emphasize its fast readability. The QR code was released under a free license, which allowed it to gain widespread adoption beyond the automotive sector, expanding into industries such as logistics, commerce, marketing, and healthcare. {{Cite web |date=January 29, 2024 |title=The crazy story of QR code, Masahiro Hara's interview by Konbini |website=YouTube |url=https://www.youtube.com/watch?v=m6us-ZonVPE}}

In the early 2000s, QR codes began to be integrated into mobile phones in Japan, where they were initially used to link to websites. This marked a turning point for the global spread of the technology, further accelerated by the rise of smartphones around 2010.

By 2024, during the 30th anniversary of the QR code, Hara expressed pride in seeing his invention adopted worldwide across diverse fields, including design, healthcare, and even tattoos. He also highlighted its cultural appropriation by artists like qargo, who creatively combined QR codes with Lego bricks to produce interactive and unique portraits that tell inspiring stories.

For his groundbreaking work, Masahiro Hara was awarded the European Inventor Award in 2014.

Denso International America is the American subsidiary of Denso.

In 1970, DENSO Corporation decided to expand overseas from Kariya, Japan, to North America. DENSO Sales California, Inc., was founded in Hawthorne, California, in March 1971. The company was staffed with only 12 associates, four of them being Americans. The objective of DENSO Sales California was to promote their air conditioner systems as options in Japanese-made vehicles.

In May 1975, DENSO Corporation opened a sales division, Denso Sales, in Southfield, Michigan.

In September 1975, DENSO International America opened a service center in Cedar Falls, Iowa. This was opened due to an agricultural parts contract with John Deere that included starter motors and meters.

DENSO International America employs over 17,000 people at 38 locations between North, Central, and South America. At year end, on March 31, 2008, combined sales totaled $8.3 billion for all American locations.{{cite web|title=About Us Overview | DENSO International America, Inc|url=http://www.densocorp-na.com/corporate/philosophy.html|access-date=2012-03-25|publisher=Densocorp-na.com}}Proud Past, Strong Future: A History of DENSO’s First 50 Years (pg. 112-115)

As Denso is a part of the Toyota Group, it also assists Toyota in participating and developing their cars for different motorsports categories. Denso manufactures customised electronics and different auto-parts specifically for Toyota-Lexus motorsports development divisions Toyota Racing Development and the European motorsports facility of the company Toyota Gazoo Racing previously named Toyota Motorsports GmbH located in Germany. Denso plays a vital role as an OEM by specifically engineering auto-parts and electronics for Toyota in motorsports which mainly include spark plugs, starter motors, fuel pumps, alternators, Engine Control Module (ECM) computer systems, engine & transmission sensors and many other high-performance automotive and motor racing equipments and accessories for Toyota to compete in a variety of motorsports categories which include NASCAR, Formula One (from 2002-2009), World Rally Championship, and World Endurance Championship. The Toyota TS030 Hybrid, using a Denso kinetic energy recovery system, finished second in the 2013 24 Hours of Le Mans.

Denso products are also used in many local Japanese motorsports, including Super Formula and Super GT.

On January 30, 2012, the US Justice Department announced after two years of investigation that it had discovered part of a massive price fixing scheme in which Denso and Yazaki played a significant role. The conspiracy, which fixed prices and allocated components to such car manufacturers as Toyota and Honda, extended from Michigan to Japan, where it was also under investigation. Denso agreed to pay a fine of $78 million.{{Cite news|last=Bunkley|first=Nick|date=2012-01-30|title=Japanese Auto Suppliers Are Fined, and Executives Agree to Prison, in a Price-Fixing Case (Published 2012)|language=en-US|work=The New York Times|url=https://www.nytimes.com/2012/01/31/business/japanese-auto-suppliers-fined-in-us-price-fixing-case.html|access-date=2020-12-02|issn=0362-4331}}Associated Press, "U.S. fines Japanese auto parts suppliers $470 million", Japan Times, 1 February 2012, p. 1.

In August 2020, a class-action lawsuit was filed in Quebec over alleged defective fuel pumps in a number of Acura, Honda, Lexus, Subaru, and Toyota vehicle models. A separate fuel pump lawsuit was filed for the remaining areas of Canada.{{cite web|date=3 August 2020|title=Denso Canada Lawsuit Filed Over Fuel Pumps|url=https://www.carcomplaints.com/news/2020/denso-canada-lawsuit-fuel-pumps.shtml|access-date=August 4, 2020|work=CarComplaints.com}}
