OkayamaInternational Circuit

The TI Circuit Aida (now known as Okayama International Circuit) is a 3.703-kilometre Japanese road course that hosted the briefly-lived Pacific Grand Prix in 1994 and 1995. Set in the rural Okayama prefecture about 700 kilometres west of Tokyo, the circuit was Bernie Ecclestone's experiment in adding a second Japanese F1 round to the calendar — an attempt that failed commercially after just two editions, both of which were overshadowed by tragedy.

Origins

The TI Circuit Aida was opened in 1990 by the Tanaka International group, a Japanese real-estate conglomerate, as a permanent road course intended to host major international motorsport events. The 3.703-kilometre layout was designed by Japanese engineers in consultation with Ecclestone's office. The Pacific Grand Prix was added to the F1 calendar in 1994. The race was held in April 1994, just two weeks before the catastrophic San Marino Grand Prix at Imola where Ayrton Senna and Roland Ratzenberger were killed. The 1995 race was held in October — moved from April to avoid conflict with the Pacific typhoon season — and was Michael Schumacher's emphatic victory. The race was poorly attended, and the Pacific Grand Prix was removed from the F1 calendar after 1995.

Layout

The 3.703-kilometre lap had 13 corners arranged in a tight, twisting configuration with significant elevation changes. The famous "Atwood Curve" was a fast right-hander with significant camber praised by drivers. The 920-metre back straight saw cars typically reaching only 290 km/h.

Legendary Moments

The 1994 race was Michael Schumacher's emphatic victory just two weeks before the catastrophic San Marino Grand Prix — the result gave Schumacher his first F1 victory of the 1994 season. The broader narrative was overshadowed by the Imola tragedy. The 1995 race was Schumacher's second consecutive Pacific Grand Prix victory and a key moment in his second consecutive World Championship campaign. The race was poorly attended, with estimated crowds of less than 30,000 across the weekend.

Quirks & Curiosities

The Pacific Grand Prix was the calendar's first attempt to establish a second F1 round in Japan. The remote rural location — 700 kilometres west of Tokyo — made the circuit one of the most logistically difficult F1 venues to attend. The 1994 Pacific Grand Prix was held just two weeks before Senna's death at Imola. The Brazilian retired from the Pacific GP with a clutch failure on lap 1, making the Okayama race a poignant final memory of his career.

Modern Era

The Pacific Grand Prix has not been held since 1995. The Okayama International Circuit continues to host Japanese national motorsport championships. The Japanese F1 calendar is now focused exclusively on Suzuka.
