The 2009 Formula Challenge Japan was a multi-event motor racing championship for open-wheelformula racing cars, and the fourth season of the Formula Challenge Japan racing series, a young driver development series jointly supported by Honda, Toyota, and Nissan. The championship featured a mix of manufacturer-affiliated drivers and independent entries, and commenced on 4 April and ended on 27 September.[1][2] All championship rounds were run in support of the Formula Nippon Championship.
Honda Formula Dream Project driver Kazuki Miura [ja] won the championship in his second year in the series, taking four consecutive race victories to claim the title over Nissan-supported Daiki Sasaki. All race winners - Miura, Sasaki, third-placed finisher Naoya Gamou, and his Honda stablemates Makoto Kanai and Tsubasa Mekaru - won both races of their winning race weekends, with the first round at Fuji Speedway being the only round to have two different race winners.
All drivers competed in identical Tatuus FC106 chassis powered by Nismo-maintained Renault F4R engines. The entry list originally consisted of 27 entries, but would drop to 18 entries, largely due to the repercussions of the 2007–2008 global financial crisis in Japan.[3]
