The Indy Japan 300 presented by Bridgestone was an Indy Racing League IndyCar Series race held at Twin Ring Motegi in Motegi, Japan. The 2008 race marked the historic first ever win for a woman driver in American open wheel racing when Danica Patrick of Andretti-Green Racing took the checkered flag.
The first American open-wheel race in Japan was held in 1966 at Fuji Speedway. Jackie Stewart won the Fuji Japan 200, which was held as an exhibition race, and no championship points were awarded. USAC did not return.
For a short period in the late 1980s and early 1990s the CART series explored the prospects of holding a race in Japan. Possible locations would be either Suzuka, Fuji, or a street course in another city. The FIA objected, citing conflicts with Formula One and other interests. In addition, rules were put into place requiring that any CART race outside of North America be held on an oval. Despite the objections, in 1991 CART made their first trip across the Pacific Ocean, and held a street race at Surfer's Paradise, Australia. The plans for a race in Japan were scrapped.
In 1994, Honda joined the CART series, and by 1996, was widely successful. Interest in holding a race in Japan resurfaced, and upon the completion of the Twin Ring Motegi oval, a race was first held in 1998 without FIA objection. The race continued as a Champ Car event through 2002. In 2003, Honda switched alliances to the Indy Racing League, and the race became an Indycar Series event. On February 9, 2011, it was announced that the series would not return to Motegi for the 2012 season.
