Tommykaira, originally founded as Tomita Yume Koujou is a Japanese car tuning and manufacturing company founded in 1986 and headquartered in Minami-ku, Kyoto, Japan. The company was named after its two founders, Yoshikazu Tomita and Kikuo Kaira. 

By 1996, Tommykaira had solely modified pre-existing models manufactured by Nissan and Subaru; nonetheless, the heavy improvements worked out by the company on the cars made it gain recognition as a brand in its own right.

The company decided to develop its own original design, the ZZ. The ZZ was produced in Ironside way, Hingham, Norfolk, England, but the factory that manufactured the ZZ collapsed due to a blunder of the Japanese Ministry of Transportation which, in 1999, switched front impact requirements from European to US standards. In 2002, the car was relaunched as the Leading Edge 190 RT built by Breckland Technologies.
