Shinseido T-180

Shinseido is the fan name of a background car from the Speed Racer film. It's unknown if "Shinseido" is a sponsor or just an unrelated phrase on the car. It has two versions appearing at Fuji and the Grand Prix

Fuji Helexicon
A version that is mostly white with the Great Wave of Katagawa painting as a livery (and various red Japanese text according to the concept art) appears very briefly at the Fuji Helexicon race. This version is always seen in last place, not getting any of the spotlight.

Grand Prix
A version that is white and black with green text appears in the Grand Prix. The car can be seen in the back of the pack at the start. It’s seen again on the moguls behind Speed. The car stays low profile for the rest of the race, but is passed a final time by Speed on a straightaway on the final lap.

Trivia

 * The name "Shinseido" comes from the Japanese text "88新星堂" plastered on the various parts of the car.
 * The sponsor "KaraSugoi" is on the car's spoiler.
 * The sponsor "ULUL" (ウルル) is on the top parts next to the front wheels and on the car's sides near the back.
 * The sponsor "Sumiya" (すみや) is on the car's sides and at the top. It references a real life CD/DVD store.
