The company started in 1982 as Twin Power, later became closely associated with HKS under the HKS Kansai Service name, and today operates as Kansai Service. Their own history page lists the 1982 founding, and a Yokohama/ADVAN feature describes the shop as having led the Japanese tuning scene for over 40 years through names including Twin Power, HKS Kansai Service, and Kansai Service.
