Aisin Seiki Co., Ltd. (アイシン精機株式会社 Aishin Seiki Kabushiki Kaisha), also known as Aisin, is a Japanese corporation which develops and produces components and systems for the automotive industry. Aisin is a Fortune Global 500 company, ranked 442 on the 2015 rankings.

Aisin Seiki was founded in 1949 and currently 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.

Aisin is 30% owned by the Toyota Group of companies.

Aisin AW

Aisin AW is a major automotive technology manufacturer. Established in 1969, it developed the Prius transmission and the world's first speaking navigation system.

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

Aisin AI is an independent company under Aisin Seiki. It was spun off in July 1991, moving its headquarters to Nishio City. Aisin AI supplied only Toyota through 1996, when DaimlerChrysler and Isuzu began using their products. The company later added Mazda, Nissan, Mitsubishi Motors, General Motors, Daihatsu, Hino Motors, Fiat Automobiles, Volvo, Jeep, Porsche, and Luxgen.

Aisin USA

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.

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.
