The Okayama International Circuit, located near Mimasaka in Japan's Okayama Prefecture, has a rich history in motorsport, marked by its origins as a private racing facility and its evolution into a venue for international competitions. Initially known as TI Circuit Aida, the track was conceived with ambitious goals, including hosting Formula 1 races, and has since seen various ownership changes and hosted a range of significant events, contributing
to Japan's standing in the global racing community.
The Genesis of TI Circuit Aida
The circuit's story began in 1990 when it was opened as a private motorsport racetrack. The initial vision was to create a high-end facility for a wealthy clientele. The name "TI" stood for Tanaka International, after Hajime Tanaka, a golf club owner who decided to invest in motorsport. Tanaka had inherited several golf courses, and by the late 1980s, membership fees in Japan had soared. He opted to sell some of these properties and redirect his investments into auto racing. He acquired land in Aida for $100 million to build the circuit.
To cover the substantial costs of the track, Tanaka established the TI Sports Club, charging a membership fee of $100,000, which granted lifetime access. To ensure member satisfaction, he also built a clubhouse, hotels, and multiple garages on the premises where members could store their cars. This strategy successfully attracted 350 members, primarily private individuals, though some corporations like Toyota and Nissan also invested. The track officially opened in November 1990 with a grand ceremony attended by racing legend Stirling Moss, signaling its aspirations for a prominent role in motorsport.
Hosting Formula 1 and Overcoming Challenges
Tanaka's ultimate ambition was to host a Formula 1 race at his circuit, a goal he achieved with the support of Okayama Prefecture, which sought to boost tourism in the region. The prefecture hoped that visitors attending the races would also explore local attractions. The circuit hosted two Formula 1 Pacific Grand Prix events in 1994 and 1995. The first race in 1994 made Japan one of only nine countries at the time to host more than one Formula 1 event in a single year. Due to the track's relatively short length of 3.703 kilometers (2.301 miles), drivers had to complete 83 laps during the race. Michael Schumacher won both Formula 1 races held at the circuit.
However, the circuit faced significant logistical challenges due to its remote location. It was situated in a mountainous, heavily forested area, approximately 12 miles from the nearest town. Hotels were scarce, requiring Formula 1 attendees to travel 30-40 miles for accommodation. Major Japanese cities like Osaka and Tokyo were 150 and 500 miles away, respectively. The 1995 race, initially scheduled for April, was postponed to October following a major earthquake in January that severely affected Kobe, disrupting local infrastructure and communication channels. While travel issues might have been resolved, authorities felt it was inappropriate to hold such an event while rescue efforts were ongoing in the Kobe area. Despite these hurdles, Tanaka realized his dream of hosting Formula 1, though the high costs and the politicians' decision not to continue the experiment meant no further Formula 1 Grands Prix were held there.
Evolution and Modern Era
After its Formula 1 tenure, the circuit continued to host other significant events. In August 1996, it was slated to host a round of the International Touring Car Championship, replacing the F1 race, but this event was moved to Suzuka Circuit. A tragic incident occurred on March 11, 1999, when 21-year-old Tachi Shingo, the reigning Super GT GT300 champion, died during testing. A technical malfunction in his GT500 Toyota Supra prevented him from slowing down, leading to a high-speed impact with a tire wall in the first corner. He sustained severe chest injuries and passed away an hour later.
On January 1, 2005, the circuit was officially renamed Okayama International Circuit. This change followed the acquisition of the track by Unimat from Tanaka International in 2003. On March 31, 2005, the town of Aida merged with surrounding municipalities to form the larger city of Mimasaka. The circuit continued to attract international motorsport, hosting a round of the Formula V6 Asia and the penultimate round of the World Touring Car Championship (WTCC) on October 26, 2008. This WTCC event marked the first FIA World Championship race at the circuit since 1995. Tom Coronel secured his first WTCC victory there. The WTCC returned in 2009 and 2010, but in June 2010, it was announced that Suzuka Circuit would host the Japanese round of the series from 2011 onwards. On March 3, 2012, Unimat sold the circuit to Aska Corporation, an automotive parts manufacturer, marking another chapter in the circuit's ongoing history.
