The 2002 Formula Nippon Championship was the thirtieth season of premier Japanese single-seater racing, and the seventh under the Formula Nippon moniker. The series was contested over 10 rounds at five venues. 11 different teams and 22 different drivers completed in the series.
Reynard became the sole supplier of chassis to all teams after the withdrawal of G-Force Technologies, but this would only last one season after the company declared bankruptcy in February 2002.
Nakajima Racing driver Ralph Firman won the series championship before moving to Formula One in 2003.
All teams used tyres supplied by Bridgestone and Mugen MF308 engines.
All races were held in Japan.
