Tommykaira (トミーカイラ), formally Tomita Yume Hanbai (株式会社トミタ夢販売), was a Japanese car tuning and manufacturing company founded on May 1, 2002 and headquartered in Minami-ku, Kyoto, Japan. The company was named after its two founders, Yoshikazu Tomita and Kikuo Kaira. Its parent company was founded in 1968 as Tomita Yume Kōjō (株式会社トミタ夢工場). Several of its Tommykaira's custom cars have appeared in both the Gran Turismo and Forza Motorsport racing simulation video game series.
In 1987, Tommykaira unveiled a tuned Mercedes-Benz 190E which was renamed as the "Tommykaira M19". The company subsequently released the M30E, which was based on the Mercedes-Benz 300E. However, from 1988 onwards Tommykaira began to exclusively work on automobiles made in Japan, establishing successful contracts with manufacturers Nissan and Subaru. In 1988, the company tuned for the first time a Nissan Skyline R31 (rebranded as Tommykaira M30), in 1993 the turn was for the Subaru Impreza (M20b) and the Nissan March (m13) and, finally, in 1994 the first Subaru Legacy Wagon (M20tb) received attention from the Kyoto-based company. The company focused most of its efforts on mechanical and aesthetic modifications to four cars- the Nissan Skyline, Nissan March, Subaru Impreza and Subaru Legacy.
Other models modified have included the Nissan 300ZX, Nissan Silvia, Nissan GTR R35, Toyota Vitz, Nissan 350Z and several kei cars from various manufacturers. Tommykaira has consistently rebranded the cars as if they were completely manufactured by the company itself, with the consent of the parent manufacturers: for example, a Subaru Impreza is rebranded as Tommykaira M20b or a Nissan 350Z as a Tommykaira Z. This phenomenon is not unusual around the world as German manufacturers such as Ruf and Gemballa operate in a similar way with Porsche automobiles.
On the other hand, the rebranding process carried out by Tommykaira has evoked some controversy directly related to the status of the company as a car manufacturer. According to the information spot provided by the PlayStation video game Gran Turismo 2 about the Kyoto-based company, "in 1988 succeeded in introducing Tommy Kaira M30, Japan's first fully modified high performance car in 1997, manufactured and marketed its original sports car, the ZZ". In general terms, the 1988 M30 model is regarded as the first integrally tuned Japanese automobile, an integral tuning that implied rebranding of the original model. This fact acknowledged the capability of Tommykaira as an important aftermarket manufacturer and prepared the way for the launch of the company as a consolidated car manufacturer with the self-conceived 1996 ZZ model.
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.
