Technical Specifications and Track Features

The Okayama circuit presents a demanding course with a unique character defined by its blend of slow technical sections and faster sweeping corners. The track width ranges from 10 to 15 meters throughout, allowing for competitive racing while requiring precise driving. Its main straight extends approximately 900 meters, offering crucial overtaking opportunities before the challenging first corner. Notable features include the tight hairpin at Turn 11, which demands heavy braking, and the technical esses section that rewards precise car control.

History

Opened in 1990 as TI Circuit Aida, the track was initially designed for national events before gaining international recognition. Its most significant historical milestone came in 1994 and 1995 when it hosted the Formula One Pacific Grand Prix, with Michael Schumacher and David Coulthard claiming victories respectively. After a period of reduced prominence, the circuit was purchased and renamed Okayama International Circuit in 2004, initiating a revival in its fortunes. The track underwent significant renovations to meet modern safety standards while preserving its challenging character. In recent years, Okayama has become a staple venue for the Super GT series, Japanese Formula 3 (now Super Formula Lights), and various national championships. The circuit continues to develop its facilities while maintaining its reputation as one of Japan's most technical and rewarding driving challenges, beloved by drivers and spectators alike for its old-school character and beautiful rural setting.
