Okayama International Circuit, named TI Circuit Aida until December 31, 2004, is a 2.301-mile (3.7 km) private motorsport race track in Mimasaka, Okayama Prefecture, Japan. The course was opened in 1990 as a private race track for the wealthy. Soon, it hosted its first race, staged by veteran British drivers. In 1994 and 1995, the TI Circuit hosted the Formula One Pacific Grand Prix; both events were won by Michael Schumacher in his early title-winning years. This race made Japan one of only seven countries to ever host more than one Formula One event in the same year. It was discontinued primarily due to its location in a remote area of Japan.
