Which city is Toyota City twinned with?

Explanation

Toyota is Japan's and the world's largest automobile manufacturer by production. The company started as a spin-off from a textile machine company founded by Sakichi Toyoda and in 1937 the son, Kiichiro Toyoda, created an independent company. Toyota is headquartered in the cities Nagoya and Toyota City. The latter used to be called Koromo and was known for its silk production. As it dwindled, Toyota moved in, and in 1959, Koromo became Toyota City. It is twinned with the other car cities Detroit, USA and Derby, England.
