Aisin Corporation (株式会社アイシン, Kabushiki gaisha Aishin) is a Japanese corporation that develops and produces components and systems for the automotive industry. Aisin is a Fortune Global 500 company, ranked 359 on the 2020 rankings.[4] They are a member of the Toyota Group of companies.

Aisin was founded in 1965[1] and supplies engine, drivetrain, body and chassis, aftermarket, and other main automotive parts for various major OEMs. In addition to partaking in the automotive markets, Aisin also offers life and amenity products (e.g. furniture and sewing machines), energy systems, welfare products, and other products/services.[5]

Corporate History[edit]

The company traces its origins to 1943, when Tokai Aviation Industries (東海航空工業, Tōkai Kōkū Kōgyō) was founded as a joint venture between the Toyota Motor Corporation and Kawasaki Aircraft Industries to produce aircraft engines for the Imperial Japanese Army Air Service. The company was quickly renamed Tokai Airplane Industries (東海飛行機工業, Tōkai Hikōki Kōgyō) after it was discovered that there was a pre-existing company with the same name.[6]

After the war Tokai renamed itself Aichi Industries (愛知工業, Aichi Kōgyō), and shifted production from aircraft parts to sewing machines and automobile parts. In 1965 Aichi Kogyo merged with auto parts manufacturer Shinkawa Kogyo to form Aisin Seiki Co., Ltd. (アイシン精機株式会社, Aishin Seiki Kabushiki Kaisha).[1]

In October, 2019 Aisin Seiki announced they would merge with subsidiary Aisin AW, consolidating management and renaming the company.[7] Effective April 1, 2021 the combined company was officially renamed Aisin Corporation.[8]

Aisin AW[edit]

The headquarters of Aisin AW

Aisin AW was Aisin Seiki's subsidiary building automatic transmissions. It was originally established in 1969 as Aisin-Warner, a joint venture with BorgWarner. In 1981 BorgWarner reduced its equity in Aisin-Warner to 10%[9], and by 1987 had divested themselves of the remainder. Aisin-Warner was renamed Aisin AW in 1988, and merged with parent company Aisin Seiki in 2021.

It developed the Prius transmission[10] and the world's first speaking navigation system.[11]

Additionally, the two-axis Aisin AW hybrid design has been adapted to the 2016– Prius (excepting the Prius c), and has also been employed on "Gen 1" (2005-2007) and "Gen 2" (2008-2012) Ford Escape Hybrids (Aisin T-030 and T-031 eCVTs, respectively), both FWD and AWD models, with Ford providing the Atkinson Cycle engine, hybrid battery, and all software control systems, and with Ford developing the AWD functionality; and on 2017– Chrysler Pacifica Hybrid minivans (Aisin T-032 eCVT). The two-axis design eliminates the second planetary gearset ("motor speed reduction device") found in the 2010–2015 Prius and the Prius c, and which reduces the width and weight of the eCVT and improves its overall efficiency.

It is based in Anjō, near Nagoya, Japan. Another major division is located in Okazaki.

Other global locations: Headquarters for Europe : AW Europe & AW Technical Center Europe which is located in Braine-l'Alleud (Belgium) for Research and Development and in Baudour (Belgium) for the re-manufacturing of automatic transmissions/transaxles and production of electronic products.

Aisin AI[edit]

Aisin AI was an Aisin Seiki subsidiary spun off in July 1991 to produce manual transmissions and transfer cases, moving its headquarters to Nishio City. Aisin AI supplied only Toyota through 1996, when DaimlerChrysler and Isuzu began using their products. The company later began supplying products to other companies worldwide.

Aisin AI was consolidated into Aisin AW in 2019.[12]

Aisin USA[edit]

Aisin constructed a factory in the United States of America in 1986, with production beginning in 1989. This factory, in Seymour, Indiana has since been expanded and supplies components for Honda, General Motors, Mitsubishi Motors, Nissan and Toyota. The company also operates in Marion, Illinois.

On October 5, 2005, Aisin USA opened an 878-acre (3.55 km2) testing facility near Fowlerville, Michigan. Officially named FT Techno of America (FTTA), but known as Aisin's Fowlerville Proving Ground, the new venture is a member of the Aisin Group, a Tier One worldwide automotive components supplier with global sales of more than US$15 billion in 2004. In Michigan, Aisin Group companies employ 554 associates, with annual payroll of US$40 million and total investments of US$102.7 million. FTTA is Aisin's fifth group company in Michigan. In 2009, the North American based division and companies were all placed under a newly created entity named Aisin World Corp. of America. Aisin World Corp. of America was structured so that Toyota Motors Corporation, Mitsui, and Hino Motors USA have majority ownership of the Aisin entities in North America. Aisin Automotive Castings, LLC. and other North American based Aisin companies operate as subsidiaries to Aisin World Corp. of America.

The new proving ground, Aisin's first in North America, and third worldwide, is research and development based supporting test surfaces of various lengths and lane widths used to develop and evaluate a variety of Aisin products and applications, such as transmissions, brakes, drivetrains, and chassis and body systems and components.

IMRA America[edit]

IMRA America (Institut Minoru de Recherche Avancé) was founded in 1990 in Ann Arbor, Michigan, and has become a key R&D division of Aisin group. IMRA America is dedicated to creative research and innovation on laser applications, biomedical devices, and lithium-ion batteries.
