Originally appeared in Gran Turismo 2 for the Playstation, and known as simply "Super Speedway" in GT2 and GT3. It seems to have grown a bit in GT4, and is now part of Twin Ring Motegi.

Twin Ring Motegi is an automobile racing track located in Motegi, Japan. Its name comes from the fact that there are two race tracks at the facility: a 1.5 mile oval (2.414 kilometers) and a 4.8 kilometer (2.983 miles) road course. It was built in 1997 by Honda, as part of Honda's effort to bring Indycar racing to Japan, as well as increase their own knowledge of that form of racing.

The oval course is the only one of its kind in Japan, and currently is only used once a year for racing. It is a low-banked, 1.5 mile long egg-shaped course, with turns 3 and 4 being much tighter than turns 1 and 2. Because of the low banking, and because it is currently the last race on the Indycar schedule before the Indianapolis 500, it is seen as a useful tune-up venue for the teams. In addition to Indycar Racing, the track has also hosted a single NASCAR exhibition race in 1998.

In one of the great ironies of the sport, Honda, which had built the oval for the express purpose of developing its oval-racing program for Indycar Racing, did not win a race at the track for its first six years of operation. In 2004 Dan Wheldon took the first win for Honda on the oval.
