Mega Web was opened by TMC in Odaiba, an ocean-front sub-city center in Tokyo in March 1999, as a new kind of theme park focusing on cars. As an anchor facility inside the large-scale commercial and entertainment facility "Palette Town", Mega Web includes a 1.4-kilometer circuit where visitors can test drive nearly any Toyota car sold on the Japanese market. Against the initial expectation of 3 million visitors annually, Mega Web received as many as 7.89 million visitors in its second year of operation. It continues to be a popular tourist spot, receiving visitors from outside Japan as well, especially from other Asian countries.

In November 2000, TMC opened Colorful Town Gifu on idle land at the Gifu Plant of Toyoda Boshoku Corporation (now Toyota Boshoku Corporation). This was a multipurpose commercial facility containing retail stores and amusement centers, and a total of six car dealers including a Daihatsu dealer formed Japan's first auto mall. There, Toyota also accumulated expertise in operating a showroom-oriented sales outlet.
