A well-established spin-off of Toyota Motor Corporation, the DENSO Corporation (originally incorporated as the Nippondenso Company) is Japans leading producer of automobile components and the worlds fourth largest. Its products include air conditioners and heaters, electrical and electronic control products, fuel management systems, radiators, meters, and filters. General Motors leaders acknowledged DENSO as a model for GM spin-off Delphi Automotive. As the second-largest member of the Toyota Group, more than half of DENSOs products go to Toyota Motor Corporation (TMC), which owns better than 20 percent of DENSO stock. DENSO also supplies nearly all other major Japanese automakers as well as numerous U.S. manufacturers, including Ford, General Motors, and Chrysler, and major European auto manufacturers such as Volvo, BMW, and Fiat. The companys emphasis on quality control and improved manufacturing efficiency throughout its history, its aggressive international expansion program, and its well-funded research-and-development activities since the 1960s have produced steady sales growth and allowed DENSO to capture dominant positions in many of its world markets.


Nippondenso rose to its international presence from Toyota Motor Corporations in-house electrical and radiator operations, which began after Toyota Automatic Loom Works formed an automobile division in 1933. In 1936, the Japanese government passed legislation to promote domestic production of automobiles. Loom Works separated its automobile division from the rest of the company, and the motor division developed an in-house electrical-parts factory.

The inability of Loom Works to adequately fund automobile production on its own and the fact that legislation had made automobile production potentially profitable led to the 1937 establishment of Toyota Motor Corporation. Soon afterwards, the Toyota Group was reorganized around Toyota rather than Loom Works. The limited number of Japanese independent parts manufacturers in the late 1930s, especially those that produced electrical parts, led to the development of parts makers with close ties to automobile manufacturers. Shortly after Toyota Motor Corporation was formed, it built a factory in Kariya to produce starters and coils. In 1943 a radiator plant was added, and the two factories eventually became the basis for Nippondenso.

Japans involvement in World War II contributed heavily to the development of Toyota and its affiliates through wartime contracts. After Japan surrendered to the Allies in 1945, the automobile industry was reshaped by the Supreme Command for the Allied Powers, and Toyota was compelled to spin off Nippondenso as an independent company.

Nippondenso Company was incorporated on December 16, 1949 as an automotive electrical-equipment maker with ¥15 million in capital and 1,445 employees. Torao Hayashi was named president. Nippondensos first products as an independent company included starters, ignition coils, distributors, voltage regulators, radiators, meters, oil coolers and cleaners, horns, dynamos, windshield wipers, and car heaters.

In March 1950, Nippondenso announced it would cut personnel in response to recession. A two-month strike resulted and was resolved after Toyota president Kiichiro Toyoda and the companys managing director and executive vice-president resigned. Shortly thereafter, 1,760 employees retired voluntarily.

In the 1950s, Nippondenso used standardization and quality control to rise to the top of its field. Hayashi and other top executives initially viewed quality control as a means to standardize and to procure U.S. military contracts. Nippondenso also looked to foreign cooperative agreements during the decade as a way of improving standardization techniques, gaining technological knowledge, and expanding product lines.

Quality Control in the 1950s and 1960s

Following the recommendations of U.S. and Japanese quality-control experts, Nippondenso established a program that combined design, processing, and cost controls. In 1950, Nippondenso formed an inspection department that learned statistical quality-control methods. The following year use of control charts was initiated, and in 1952 random sampling and other testing methods were adopted. In 1954, the company embarked on a five-year quality control program, which included compiling a training manual for employees and subcontractors. The program initially targeted improvements in standardization and inspections. In 1956, Nippondenso established a quality-control staff office and an independent committee to oversee quality-control programs.

Beginning in 1953, Nippondenso entered a three-year technical agreement with Robert Bosch of West Germany for the production of electronic parts, fuel injection pumps, and spark plugs. As a result of the Bosch tie-up, Nippondensos product line was expanded in the latter part of the decade to include car air conditioners, engine regulating equipment, fuel injection systems, and diesel engines.

In 1957 and 1958, Nippondenso de-emphasized finished product inspection and focused quality-control efforts on improved process-control methods. At the same time, it extended quality-control techniques into design and prototype-manufacturing areas. In 1958, Nippondenso purchased precision measuring equipment and automatic inspection devices to help workers control quality themselves. By the end of the decade sales had grown 23 times from 1950 levels and surpassed ¥10 billion.

In 1960, Nippondenso began working with integrated-circuit (IC) technology and developed an electromagnetic fuel pump fitted with a diode transistor. Two years later the company created an IC device that dims headlights automatically.

In 1961, Nippondenso implemented a second five-year quality control plan that was designed to strengthen the companys management. Later that year, long-range planning efforts of the Quality Control Committee, established in 1956, along with supervisors for planning, development, and production-line activity, were recognized when Nippondenso received the prestigious Deming quality-control award.

Beginning in the latter half of the 1960s, Nippondenso expanded in a number of areas; in 1965, new domestic plants were established in Hiroshima and Ikeda to manufacture radiators, radiator-fan motors, and oil coolers. Two years later Nippondensos fourth plant, a starter and alternator production facility, was opened in Anjo.

Between 1965 and 1966, three new domestic manufacturing and sales subsidiaries were formed: Nippon Wiper Blade Co., Ltd. in Saitama Prefecture, GAC Corporation in Nagano Prefecture, and Asahi Manufacturing in Aichi Prefecture. These companies produced windshield-wiper parts, small motors for automobiles, bus air conditioners, lead wires for automobile components, and central air conditioning systems. In the following year, Nippondenso also began exporting automotive components in order to supply the growing number of Japanese automakers assembling automobiles in East and Southwest Asian countries.

North American Offices Established 1966

Nippondensos interest in marketing supplies to major U.S. automakers and an increase in Japanese-made cars exported to the United States led to the 1966 establishment of the companys first overseas facilities, which were branch offices in Chicago and Los Angeles. About the same time, liaison offices were opened in New York and Montreal. New products featuring increased automation were also introduced by Nippondenso during the mid-1960s. These included power seat and power window motors, automatic door locks, and a mechanical cruise-control system.

In 1967, Hayashi became the companys first chairman of the board. Tatsuo Iwatsuki, a former vice-president and managing director who had been with the company since its incorporation, became president.

Company Perspectives:

Mission: Contributing to a better world by creating value together with a vision for the future. Management Principles: Customer satisfaction through quality products and services, global growth through anticipation of change, environmental preservation and harmony with society, corporate vitality and respect for individuality. Individual Spirit: to be creative in thought steady in action, to be cooperative and pioneering, to be trustworthy by improving ourselves.

The company made a commitment to integrated-circuit technology in 1968 with the opening of its IC Research Center, the first of its type in the automotive industry. That same year it set up the Electronics Product Division to assemble printed circuit boards. The rapid growth of Nippondenso, especially in the latter half of the 1960s, resulted in an eightfold sales increase from 1960 to 1969. By the end of the decade the company recorded annual sales in excess of ¥90 billion.

Accelerating Globally in the 1970s

In the 1970s, Nippondenso stepped up the pace of its international expansion, research, and product development. In 1970, the company established Nippon Soken near the Nishio plant for basic automotive-component research. Also in that year the new Nishio plant in Japan began manufacturing a number of the companys principal products, including car heaters and air conditioners, radiators, radiator-fan motors, fuel injection pumps, and electronic fuel injection components. Four years later another domestic plant opened in Takatana to produce meters, oil filters, machinery, and tools.

Between 1971 and 1976, the company bolstered its worldwide presence by establishing nine overseas subsidiaries. In 1971, Nippondenso formed its first overseas subsidiary, Nippondenso of Los Angeles, to assemble and sell air conditioners and import and sell rebuilt electrical automotive equipment and spark plugs. From 1972 onward, Nippondenso formed subsidiaries in Australia and Asian nations in response to more stringent domestic content regulations.

As business with U.S. automakers expanded in the early 1970s, Nippondenso established additional import and sales subsidiaries in North America. In 1972, Nippondenso Canada was established in Toronto. Three years later, Nippondenso Sales, Inc. was set up in Detroit. In 1973, Nippondensos first European subsidiary, Nippondenso (Europe) B.V., was established in Amsterdam to import and sell air conditioners and air conditioner compressors. Also in 1973, Iwatsuki was named chairman of the board. Takaaki Shirai, another former vice-president and managing director, was named president.

Nippondenso responded quickly to changing market needs in the 1970s. After the 1973 oil crisis struck and fuel economy became an international issue, Nippondenso refocused its research-and-development programs and produced an engine control system. After air pollution became a growing concern later in that decade, Nippondenso produced an electronic fuel injection system that regulated exhaust emissions. The two developments enhanced the companys reputation and boosted sales. So did the push toward smaller, fuel-conserving cars, which increased demand for the compact Nippondenso-made components.

Other Nippondenso innovations during the decade included an electronically controlled automatic transmission developed in conjunction with Toyota in 1970. More electronically controlled systems followed, including a spark advance system, knock control system, and idle speed control system. IC-based technology produced an electronic fuel injection system, new igniters, regulators, and speed sensors. The decades innovations also included an anti-skid device, electronic cruise control, a power trunk opening computer, and such non-automotive applied electronics products as industrial manufacturing robots, an automatic fire extinguisher, and a portable refrigerator. The 1975 introduction of a new spark plug with a patented U-groove electrode, marketed by Nippondenso of Los Angeles, boosted U.S. sales and contributed to Nippondensos firm establishment in the spark plug market.

Also in 1977, Takaaki Shirai became chairman of the board, and was succeeded as president by Fubito Hirano. Hirano, like other presidents before him, had climbed the corporate ladder via the offices of managing director and vice-president. By the end of the decade 8.4 percent of net sales were coming from overseas operations. Sales over the previous ten years had grown by 500 percent, to better than ¥500 billion. The sale of automobile air conditioners and heaters continued to pace earnings, followed by growing sales of electrical components.

New Ventures, New Products in the 1980s

Sales continued to climb throughout the 1980s, although earnings slipped mid-decade due to the high value of the yen. During the decade, the company focused on product diversification, international expansion, and the construction and automation of factories.

In 1980, Nippondenso formed its first South American subsidiary, in Brazil. That same year, the company entered Malaysia with the formation of Nippondenso (Malaysia) SDN./BHD. Three years later a second Malaysian subsidiary was established. Products of the three new sales and manufacturing subsidiaries included air conditioners, air conditioner compressors, windshield washers, alternators, starters, and radiators.

In 1982, Hirano was named chairman of the board and Kengo Toda, a former vice-president and managing director, was named president. That same year Nippondenso opened a domestic plant in Daian to produce distributors, spark plugs, magnetos, sensors, and actuators.

Nippondenso bolstered its European presence in 1984 with the formation of Nippondenso (Deutschland) GmbH, an import and sales subsidiary established for air conditioners, air conditioning compressors, sensors, emission devices, and actuators. Another import and sales subsidiary, Nippondenso (U.K.) Ltd., was formed in 1984 to handle windshield washers, emission control products, and air conditioner parts.

Nippondensos new products during the first half of the 1980s focused on automobile components emphasizing comfort, safety, and improved driving capabilities. Comfort-related items included a knee warmer, a seat heater, and a mosquito killer. Expanded electronics technology produced an electronically controlled diesel injection system, an electronic suspension control system, and a traction-control system. Nippondenso, which had a history of producing a majority of its specialized manufacturing equipment itself, also entered the automation business during the early 1980s, with the introduction of a magnetic stripe card reader recognition system and a bar-code scanner.

In 1985, Nippondenso posted its fifth consecutive year of increased sales and earnings, reaching all-time highs of ¥954 billion and ¥42.8 billion, respectively. Company officials attributed financial gains largely to increases in overseas production and domestic sales. Nippondensos strongest push in overseas expansion during the decade was in the United States. In 1984, the marketing and service joint venture A-B Nippondenso was formed when Nippondenso and Allen-Bradley Company of the United States agreed to cooperate on factory automation. The agreement called for cooperation in the development and sales and service of electronics products and was designed to help Nippondenso advance in factory automation and to help Allen-Bradley, a major manufacturer of control devices and factory automation systems, enter the Japanese market.

In 1984, the wholly owned subsidiary Nippondenso Manufacturing U.S.A. was formed in Battle Creek, Michigan, for the manufacture and sale of radiators, car heaters, refrigerators, cooling units, condensers, and windshield washers. The $18 million Nippondenso Technical Center U.S.A., in Southfield, Michigan, was established in 1985. The centers goal was to provide engineering services for U.S. customers, test product designs, and perform other research-and-development activities. That same year Nippondenso developed its second comprehensive domestic testing facility at its corporate headquarters. The new Kariya facility was equipped with laboratories to simulate weather for visibility evaluation, and to simulate driving.

Net sales continued to grow in 1986 and 1987 and passed ¥1 trillion, but net profits declined as a result of the rapidly appreciating value of the yen. Net earnings fell better than ¥10.4 billion in 1986 and ¥1 billion the following year. In 1987, Toda was promoted to chairman, and Taro Tanaka assumed the duties of president. Two domestic plants in Toyohashi and Kota were also opened in 1987.

In the late 1980s, rapid expansion continued, accompanied by increased net earnings. Between 1987 and 1989 five major U.S. subsidiaries were formed, including three joint ventures. In January 1989, Michigan Automotive Compressor, Inc. was formed as a joint venture between Nippondenso and Toyoda Automatic Loom Works, for the manufacture and sale of air conditioning compressors and magnetic clutches. In September of that year, Nippondenso established Purodenso Company in Jackson, Tennessee, as a 5050 joint venture with Purolator Products Company of Tulsa, Oklahoma, to produce and sell air cleaners and oil filters for Toyota, Saturn Corporation, and others. Two months later Nippondenso and Robert Bosch GmbH founded Associated Fuel Pump Systems Corporation as a 5050 joint venture to produce fuel pumps for Big Three and Japanese automakers operating in the United States.

Nippondenso also continued expansion outside of North America in the late 1980s. In 1987, manufacturing and sales subsidiaries were established in Taiwan and Thailand. Nippondenso Tool and Die (Thailand) Co., Ltd. was Nippondensos first offshore producer of dies, and Nippondenso Taiwan Company was set up to produce electrical automotive equipment, radiators, and automotive heaters and air conditioners for Toyotas subsidiaries in Taiwan.

In the first broad-based cooperation agreement among Japanese auto-parts makers belonging to different groups, Nippondenso agreed in 1987 to help an Isuzu Motors affiliate with radiator production techniques. Nippondenso Finance (Holland) B.V. was also established in 1987. This subsidiary was to carry out group finance and fund-raising activities in the European market. In 1988, Nippondenso struck a deal with Champion Spark Plugs to produce 20 million spark plugs annually under the Nippondenso brand name.

In 1989, Nippondenso and Japans Shinwa Tsushinki Company agreed to cooperate on the development of mobile communications. That same year, Nippondenso and Valeo, the largest French automotive components manufacturer, together established VND in Spain, to produce and sell distributorless ignition coils.

In 1989, Nippondenso also acquired IMI Radiators of the United Kingdom. The new subsidiary, which specializes in production of oil coolers, intercoolers, and radiators for European automakers, was renamed ND Marston. Nippondenso also formed Australian Automotive Air, Pty. Ltd. in 1989 to manufacture condensers, cooling units, and electric fans for car air conditioners.

Nippondensos growing interest in the home, office, and factory automation markets resulted in a number of new products in the latter half of the 1980s, including a programmable controller for manufacturing equipment, marketed through A-B Nippondenso. Nippondenso also introduced new factory automation products, including a compact bar-code handy scanner, marketed as the worlds smallest and lightest, and a bar-code handy terminal, which combined scanning, storing, and transmission functions. Security systems making use of finger print-reading devices, a hands-free automobile telephone, and an automobile facsimile transceiver were also introduced. Other new automobile components included a navigation system and a traction-control system.

After a profit decline in 1986 and 1987, Nippondenso closed the decade with a rebound in earnings, which climbed to a high of ¥48.3 billion in 1989, while net sales reached ¥1.3 trillion. Sales continued to be paced by car air conditioners and heaters, which accounted for about 36 percent of revenues, and electrical automotive equipment, which represented about 20 percent of sales.

Going Global in the 1990s

Nippondenso entered the 1990s by breaking into the Italian market with the January 1990 formation of Nippondenso (Italia), for the import and sale of starters and alternators. In February 1990, Nippondensos tenth domestic plant began operations in Agui, producing machinery and tools.

Nippondensos plans for the future were represented in the companys motto: to be pioneering, innovative, and creative. Further international expansion was planned with the goal of establishing a comprehensive global presence and a leading share in at least 15 of its major product markets, concentrating on improvement of electronic components, communications systems, ceramics actuators and heaters, factory-automation systems, information devices, environmental cooling control systems (for factories, offices, and trains), and refrigeration systems for perishable-food delivery trucks.

A global recession eventually cut into sales of Japans luxury autos, with a corresponding decline for Nippondenso, which had invested ¥3 billion in air conditioners and navigation systems for Toyotas Lexus line. The recession also resulted in automakers putting more pressure on Nippondenso to reduce prices. Exchange rate fluctuations were another factor in a three-year slide in profits. More parts were being sourced in America, both by Japanese carmakers and by Nippondenso itself. On a more promising note, by the end of 1991, Toyota was responsible for only half of Nippondensos total sales.

Tsuneo Ishimauru, an engineer and 30-year company veteran, was appointed president in March 1991. Diversification was a key feature of his plan to keep the company profitable. However, non-parts operations only accounted for four percent of sales in 1993. Car heaters, air conditioners, and electrical control parts were each accounting for about a third of sales.

In late 1994, an equally owned joint venture (Yantai Shougang Nippondenso Co.) was created to produce auto air conditioners in China. Nippondenso Mexico S.A., formed in September 1994, was preparing to supply measuring instruments to Chrysler Corp. Yet another Asian subsidiary, DENSO International Singapore Pte. Ltd., was formed in 1995.

Nippondenso shortened its name to DENSO Corp. in October 1996, reflecting its global orientation. The automotive industrys prospects were proving better outside Japan at that point.

DENSO was investing in intelligent traffic system projects such as automated toll systems. Increasing restrictions on diesel engine exhaust prompted to increase capacity for production of its line of fuel injection systems for diesel engines. The company was also increasing production of components in England to supply European makes.

In the late 1990s, DENSO aimed to increase sales to the Big Three automakers in the U.S. Sales to Japanese transplantsthe factories set up by Japanese carmakers in North America to meet regulatory quotashelped make DENSOs North American unit a $2.7 billion company in 1997 (the parent companys revenues were $13 billion). However, GM, Ford, and Chrysler accounted for only a fraction of sales. At the same time, the auto-parts divisions of GM (Delphi Automotive) and Ford (Visteon) were looking to increase their own business with Japanese automakers. Chrysler Corp. was DENSOs biggest customer in the U.S. Its merger with Germanys DaimlerBenz AG caused DENSO some concern, as consolidating companies typically sought to reduce trim their lists of suppliers.

In 1999, DENSO acquired the climate control division of Magneti Marelli S.p.A. of Italy for $430 million. In June 2001, it bought out ArvinMeritors 50 percent interest in Purodenso Company, a $110 million maker of air, oil and fuel filters in Jackson, Tennessee.

President and CEO Hiramu Okabe aimed to make DENSO Corporation the leader in all the market segments it served. Unlike his American counterparts, Okabe was not quick to close or sell underperforming units, considering them instead candidates for further investment. At the time of DENSOs fiftieth anniversary in December 1999, the company had a dozen market leading automotive products. It also had a winning bar code terminal. (One of its optical scanners read DENSOs new QRquick responselanguage of data-rich two-dimensional symbols instead of just vertical stripes.) Okabe wanted the company to have 25 number one products by 2005. He aimed to increase non-automotive sales to 20 percent of the total from seven percent in fiscal 1998.

The developing market for navigation systems provided DENSO with a chance to expand its U.S. market via its unique range of expertise in a number of related areas, including cellular telephones and voice-activation technology. DENSO could offer a complete drivers information/entertainment system to automakers for a retail price of $2,000 each.

In May 2001, DENSO announced it was ceasing production of mobile phones, which it had begun producing in 1992. That year alone, the company lost ¥10 billion ($82 million) on the venture. In the same year, plans were announced to merge its bar code scanner and factory automation units and spin them off as DENSO Wave, Inc.
