The largest circuit in Kyushu.

The largest circuit in Kyushu.
GT and formula races are held.
It's also cheaper to run by yourself than other circuits.
Even if there is a problem with the vehicle, there are nearby places such as TMR for 4 wheels, Karetei for 2 wheels, etc. so it is safe to have trouble when traveling by car or stopping by.
The beef skewers at Karetei, which has a store in Autopolis, are also the best.
