2010 Formula Challenge Japan

The 2010 Formula Challenge Japan was a multi-event motor racing championship for open-wheel formula racing cars, and the fifth 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 22 May and ended on 7 November. Four race weekends were run in support of Formula Nippon, with the October round at Suzuka being held in support of the Formula One Japanese Grand Prix.

Toyota junior driver Yūichi Nakayama dominated the championship, taking pole position in every qualifying session and winning ten of the twelve races on the calendar to complete the most successful campaign in series history. Nissan-supported Takamitsu Matsui finished the season as runner-up with one race win, having scored less than half of Nakayama's total points, ahead of top-placed rookie and Honda junior Kazuki Hiramine. Honda stablemate claimed the remaining race victory.
