History
The company traces its origins to 1943, when  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  after it was discovered that there was a pre-existing company with the same name.

After the war, Tokai renamed itself , and shifted production from aircraft parts to sewing machines and automobile parts. In 1965, Aichi Kogyo merged with auto parts manufacturer Shinkawa Kogyo 新川産業 to form .

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

Subsidiaries

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%, 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.

Aisin AW developed the Toyota Prius transmission and the world's first speaking navigation system. Additionally, its two-axis electric continuously variable transmission has been adapted to Prius models (except the Prius C) from 2016 onward, the 1st-generation (2005–2007) and 2nd-generation (2008–2012) Ford Escape Hybrid, and the Chrysler Pacifica Hybrid from 2017 onward. The two-axis design eliminates the second planetary gearset used in the 2010–2015 Prius and Prius c, which reduces the width and weight of the eCVT and improves its overall efficiency.

Aisin AW was based in Anjō, with another major division located in Okazaki. Two European divisions, AW Europe & AW Technical Center Europe, were located in Braine-l'Alleud (for research and development) and Baudour (for the remanufacturing of automatic transmissions and transaxles, and the production of electronic components).

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

Aisin AI was consolidated into Aisin AW in 2019.

Aisin USA
Aisin constructed a factory in the United States in 1986, with production beginning in 1989. This factory in Seymour, Indiana has since been expanded and supplies components for Honda, General Motors, Mitsubishi, Nissan, and Toyota. Another factory was built in Marion, Illinois. On October 5, 2005, Aisin USA opened an  testing facility near Fowlerville, Michigan. The facility, which is Aisin's first in North America and third worldwide, is officially named FT Techno of America (FTTA), but is also known as the Fowlerville Proving Ground. FTTA is Aisin's fifth group company in Michigan.

In 2009, the North American division and its companies were placed under a newly created entity named Aisin World Corporation of America, which was structured so that Toyota, Mitsui, and the American branch of Hino have majority ownership of Aisin's North American operations.

BluE Nexus 

BluE Nexus is a joint venture company established by Aisin and Denso in April 2019 to build powertrain systems for electric vehicles. Both Aisin and Denso are members of the Toyota Group and the Toyota Motor Corporation has a 10% stake in the company.
