Kariya is twinned with Mississauga, Ontario, Canada, which has a Japanese garden to commemorate this, named after the city.
Kariya is about 30 kilometers by train from Nagoya, Japan's fourth largest city, which endured heavy bombardment during World War II.
There are companies related to Toyota Motor Corporation, such as Toyota Industries Corporation, Aisin Seiki and Denso Corporation. Toyoda Automatic Loom Works, Toyodajidoshoki, was actually the original company, or kaisha of which Toyota Motor Corporation became a subsidiary firm. Because the Loom Works was so highly profitable, board members decided to reinvest much of the profits into the growing automobile manufacturing business. A notable educational institution based in Kariya is the Aichi University of Education (AUE), a national university, and its affiliated high school. Both the AUE and AUE High School are located in the Hirosawa section of the Igaya neighbourhood.
During World War II, large towers in Kariya, funded by Germany were used to communicate the orders for Japan to attack Pearl Harbor. However, only one remains at Yosami Transmitting Station Park.
