is a Japanese multinational automobile manufacturer headquartered in Yokohama, Kanagawa Prefecture. Its principal activity is the production, marketing and sale of Isuzu commercial vehicles and diesel engines.

The company also has a number of subsidiaries and joint ventures, including UD Trucks, Anadolu Isuzu (a Turkish joint venture with Anadolu Group), Sollers-Isuzu (a Russian joint venture with Sollers JSC - Production stopped in March 2022, Isuzu stake transferred to Sollers in July 2023), Jiangxi Isuzu Motors (a Chinese joint venture with Jiangling Motors Company Group), Isuzu Astra Motor Indonesia, Isuzu Malaysia (Isuzu HICOM), Industries Mécaniques Maghrébines, Isuzu Truck (UK), Isuzu South Africa, Isuzu Philippines, Taiwan Isuzu Motors, Isuzu Vietnam, Isuzu Motors India and BYD Isuzu.

Isuzu has assembly and manufacturing plants in Fujisawa, which have been there since the company was founded under earlier names, as well as in the Tochigi and Hokkaido prefectures. Isuzu-branded vehicles are sold in most commercial markets worldwide. Isuzu's primary market focus is on commercial diesel-powered truck, buses and construction.

The company is named after the Isuzu River, the kanji of Isuzu (五十鈴), meaning "fifty bells".

History Isuzu Motors' history began in 1916, when Tokyo Ishikawajima Shipbuilding and Engineering Co., Ltd. planned a cooperation with the Tokyo Gas and Electric Industrial Company to build automobiles. The next step was taken in 1918, when a technical cooperation with Wolseley Motors Limited was initiated, yielding exclusive rights to the production and sales of Wolseley vehicles in East Asia from knock-down kits. In 1919 came the first ever Japan-produced passenger car, a Wolseley model, the Fifteen A9 15/40 НР at the Tokyo Ishikawajima Shipyard at the Fukagawa Factory. The Wolseley sourced CP truck followed two years later; 550 of these were built by 1927. In 1923 Japan was devastated by the Kanto earthquake which made the fledgling transportation infrastructure that was heavily reliant on government-owned railroads unusable due to the twisted tracks. Heavy construction vehicles were imported from the United States companies GMC and Ford to aid in recovery and reconstruction, and the company sought to contribute by producing locally built construction and heavy duty vehicles. In 1927 the company introduced its 2-ton load capacity "Sumida P-type truck" equipped with an A6 engine and a 1-ton vehicle "Sumida M-type No. 1 bus" equipped with an A4 engine. The name "sumida" was used from the Sumida River as the factory at Fukagawa was close by.

In 1929 IHI Corporation, separated part of its manufacturing business and merged with DAT Automobile Manufacturing Inc. (a predecessor of Nissan) and changed its name to Jidosha Kogyo Co., Ltd. (Automobile Industries Co., Ltd.) The names used for the products of this company, marketed as "Sumida" and "Chiyoda", have special significance in Japan. Chiyoda is a district in Tokyo where the Imperial Palace is located, and Sumida refers to a river that flows through Tokyo approximately east of the Imperial Palace. In 1934 the Tsurumi Factory opened under company name Automobile Industry Co., Ltd. and in 1937 Automobile Industries was reorganized and formed into a new company, Tokyo Automobile Industries Co., Ltd. and was founded with a capital of ¥1,000,000. The company continued to manufacture heavy duty trucks and passenger buses, realizing the need to modernize the transportation infrastructure of Japan, and was one of the primary manufacturers for the Imperial Japanese Army along with Mitsubishi Heavy Industries, and had a corporate allegiance to the Yasuda Zaibatsu. One of the vehicles it produced for the war effort was the Sumida M.2593 armored personnel carrier. In 1942, Hino Heavy Industries was split off from Tokyo Automobile Industries, becoming a separate corporation. In 1949, the company was renamed Isuzu after the Isuzu River, following a meeting with the Japanese Government's Ministry of International Trade and Industry (MITI).

Etymology The word Isuzu translated into English means "fifty bells"—hence the focus on "bell" in both the later Bellel and the Bellett. The name was used from the Isuzu River that flows near to the Ise Grand Shrine, one of Japan's most sacred and revered shrines.

Post-World War history Truck and bus production of the TX40 and TU60 series and the Isuzu Sumida bus resumed in 1945, with the permission of the occupation authorities.Ishikawa, p. 7 and has remained the primary focus of manufacture for the company, along with diesel engine production. In 1958 a factory was built at Fujisawa, Kanagawa, and in 1959 the Isuzu Elf was introduced as a medium duty cab over commercial truck which is still in production, and was also shared with the Isuzu Journey bus. Isuzu continued to maintain its market presence by providing commercial vehicles by introducing the Isuzu TY in 1966. The company is one of the primary manufacturers of commercial duty trucks and buses for public transportation, to include the Isuzu Cubic, Isuzu Gala and the Isuzu Erga along with the Isuzu Giga.

Corporate partnerships Beginning in 1953 the Hillman Minx passenger car is produced under license of Rootes Group giving the company a passenger car to compete with other Japanese manufacturers, realizing that their resources were limited and therefore sought out international partnerships. The Minx remained in production until 1962, after the 1961 introduction of Isuzu's first passenger car, the Bellel, and later the sports coupe Isuzu 117 Coupé. Being a small producer making cars which were somewhat too large and pricey for the Japanese market at the time, Isuzu spent some time looking for a commercial partner. Under pressure from MITI, who were attempting to limit the number of automobile manufacturers in Japan, a cooperation with Fuji Heavy Industries (Subaru) began in 1966. This joint sales-service collaboration was seen as the first step towards an eventual merger. The Subaru 1000 was even shown in Isuzu's 1967 annual vehicle brochure, as a suitable complement to the larger Isuzu lineup. This tie-up was over by 1968, when an agreement with Mitsubishi was formed. This ended even more quickly, by 1969, and the next year an equally short-lived collaboration was entered with Nissan.Ruiz, p. 131 A few months later, in September 1971, what was to prove a more durable capital agreement was signed with General Motors. This would see GM own Isuzu for the next 35 years.

Linking with General Motors

While the company had a long relationship with GM going back to the 1920s, the first investment of GM taking a 34% stake in Isuzu was seen in 1972, when the Chevrolet LUV became the first Isuzu-built vehicle to be sold in the United States. To symbolize the new beginning, Isuzu also developed a new logo for 1974, with two vertical pillars as stylized representations of (), the first kana in (). In 1974 Isuzu introduced the Gemini, which was co-produced with General Motors as the T-body Chevrolet Chevette. A modified version was sold in the United States as Buick's Opel by Isuzu, and in Australia as the Holden Gemini. As a result of the collaboration, certain American GM products were sold to Japanese customers through Isuzu dealerships. Holden's Statesman was also briefly sold (246 examples) with Isuzu badging in Japan during the seventies. Isuzu exports also increased considerably as a result of being able to use GM networks, from 0.7% of production in 1973 to 35.2% by 1976; this while overall production increased more than fourfold in the same period. As a result of the GM joint venture, Isuzu engines were also used by existing GM divisions (some USA-market Chevrolet automobiles had Isuzu powertrains e.g. the Chevette and early S10/S15 trucks manufactured prior to 1985).

In 1981 Isuzu began selling consumer and commercial vehicles under their own brand in the United States. The Isuzu P'Up was the first model sold to consumers as an Isuzu, rather than as a Chevrolet or Buick, along with the Isuzu Piazza sports car. Isuzu's then president Toshio Okamoto then initiated a collaboration with small-car expert Suzuki to develop a global small car for GM, the S-car. A three-way agreement of co-ownership was signed in August 1981, with Isuzu and Suzuki exchanging shares and General Motors taking a 5% share of Suzuki. Following on from this, in 1985 Isuzu and GM established the IBC Vehicles venture in the United Kingdom, producing locally built versions of Isuzu and Suzuki light vans (the Isuzu Fargo and Suzuki Carry); to be sold in the European market under Vauxhall's Bedford brand. During this period Isuzu also developed a worldwide presence as an exporter of diesel engines, with their powerplants in use by Opel/Vauxhall, Land Rover, Hindustan, and many others. Two Isuzu model lines (Gemini, Impulse) were marketed as part of the Geo division (Spectrum, Storm) when it was initially launched as a Chevrolet subsidiary. In the domestic Japanese market, OEM deals with other manufacturers were entered to aid the poorly performing passenger car arm. It led to the badging of Suzukis, beginning in 1986, and Subaru small commercial vehicles as Isuzus (Geminett, Geminett II). This OEM tie-up occurred alongside the establishment of SIA (Subaru-Isuzu Automotive), an American joint venture with Fuji Heavy Industries (the parent company of Subaru). Shortly afterwards, the Lafayette, Indiana plant became operational.

Contraction begins

Isuzu ended US sales of the Impulse (Geo Storm) in 1992, and the following year it stopped exporting the Stylus (the basis for the Geo Spectrum), the last Isuzu-built car sold in the US.

In 1993 Isuzu began a new vehicle exchange program with Honda, whereby Honda sold the Isuzu Rodeo and Isuzu Trooper as the Honda Passport and Acura SLX, respectively. In return Isuzu began selling the Honda Odyssey as the Isuzu Oasis. Thus, Honda's lineup gained two SUVs, and Isuzu's lineup gained a minivan. In the Japanese market, the Gemini (Stylus) was now a rebadged Honda Domani and the Aska (originally based on the GM J-car) was a Honda Accord, while Honda received the 2-door MU as the Jazz and the 4-door Trooper as the Horizon.

Isuzu's United States sales reached a peak in 1996 after the introduction of the Isuzu Hombre pickup, a badge-engineered GM truck (using the sheetmetal of the Brazil-market Chevrolet S10). Isuzu resurrected the Amigo in 1998, before changing the name of the 2-door convertible to Rodeo Sport in 2001 in an attempt to associate it with the better selling 4-door Rodeo. The new Axiom launched in 2001, with the fictional salesman Joe Isuzu from 1980s advertising campaigns brought back to promote it. Isuzu sales began to slide due to the aging of the Rodeo and Trooper, and poor management and a lack of assistance from GM. The Rodeo Sport was discontinued in 2003, while production of the Rodeo and Axiom ceased a year later. By this point sales in North America had slowed to just 27,188, with the discontinued Rodeo and Axiom making up 71% of that total.

In 1998 GM and Isuzu formed DMAX, a joint venture to produce diesel engines. GM raised its stake in Isuzu to 49% the following year, effectively gaining control of the company, and quickly followed this up by appointing an American GM executive to head Isuzu's North American Operations. This marked the first time a non-Japanese executive had held such a high position at Isuzu. In 2001 GM and Isuzu announced plans to share distribution networks and for Chevrolet to market an Isuzu product.
