2005 Formula Nippon Championship
The 2005 Formula Nippon Championship was the thirty-third season of premier Japanese single-seater racing, and the tenth under the Formula Nippon moniker. It was contested over nine rounds at five venues. The newly renovated Fuji Speedway returned to the calendar, replacing Sepang International Circuit. Miné Circuit, which had been a staple venue of the series since 1977, closed for spectator events after 2005. Eight teams and 17 drivers competed in the series.
This would be the final season for Mugen as the sole engine supplier to Formula Nippon, with Toyota and Honda introducing new engines for the 2006 season.
Satoshi Motoyama of Team Impul won his fourth series championship, becoming the most successful driver of the "modern era" of Japanese top formula racing.[1]
