2000 Formula Nippon Championship

The 2000 Formula Nippon Championship was the twenty-eighth season of premier Japanese single-seater racing, and the fifth under the Formula Nippon name and Japan Race Promotion (JRP) management. The series was contested over ten rounds at five venues. 13 different teams, 21 different drivers, and two different chassis suppliers competed in the series.

Nakajima Racing driver Toranosuke Takagi, who returned to Formula Nippon after two seasons in Formula One, won his first series championship and set a new single-season record with eight wins. Takagi moved to the CART Championship Series the following year.
