Despite an oil crisis at the time, the two were able to show productive results and a healthy development of motorsports for Toyota. With the support of Toyota, TOM'S went into business in 1974.
In 1975 the Toyota Motor Corporation officially recognized TOM'S as an authorized tuning shop. In 1978, the firm opened a garage in the Tama area of Tokyo. The tuning firm expanded to Norfolk, England with branch openings in 1987.
