When were Calsonic and Kansei merged?

On April 1, 2000, Calsonic Corporation and Kansei Corporation were merged. At the time, the name “Calsonic Kansei Corporation” was established by integrating two companies’ names.
The name “Calsonic” was created in 1976 as the company name of US region when the first overseas production plant was established in the United States by combining “Cal” from California with “sonic” from sonic speed. The name contains a wish for the expansion of our strength like a fresh sound vibrating under the bright sunshine of California.
In 1988, celebrating its 50th anniversary of the parent company, Nihon Radiator Co., Ltd., the company name was changed to "Calsonic Corporation," which was widely known throughout the world.
The name Kansei was changed from “Kanto Seiki Co., Ltd.”, to “Kansei Corporation” in 1991 upon shifting from the Second Section of the Tokyo Stock Exchange to the First Section in August 1990, its 35th anniversary in 1991, and the expansion of business from a manufacturer specializing in instruments to plastics and electronics.
