Which fictional racing event begins in Tokyo in Pixar's Cars 2?

The World Grand Prix is the fictional racing event that begins in Tokyo in Pixar's Cars 2.

Cars 2 follows Lightning McQueen as he competes in a three-race international contest organized by Sir Miles Axlerod. The first race takes place in Tokyo, followed by Porto Corsa in Italy and London in the United Kingdom.

The event is promoted as a showcase for Allinol, an alternative fuel created by Axlerod. The racing plot is linked to a criminal scheme involving manipulated broadcasts and a hidden attack system, while Mater becomes involved in an international spy adventure.

The World Grand Prix differs from the Piston Cup, the domestic stock-car championship associated with the first film. Cars 2 was released in 2011 and expanded the franchise from Radiator Springs and American racing into a globe-spanning action story.
