Built on what used to be an open air sculpture park, the in 2012 opened road course of Speed Park Koinoura is a small circuit used for grip driving and gymkhana events. There is no long main straight but instead there is a large asphalted area at where normally a start/finish would be. Besides the circuit, there is also an additional asphalted circular ground which is used to lay out drift courses.
Driving on either of the courses is affordable, up to 3 cars will cost 3000 Yen for an hour, and any additional car is +1000 Yen. It is required though to take an annual membership which costs 5000 Yen. It is also possible to rent the full course. And entrance to the premises will cost 500 Yen.
Besides the grip driving and drifting course, there is also a dirt trial course. Frequently events are held on Speed Park Koinoura as the location is nearby big cities such as Fukuoka and Kitakyushu. From either of the two cities it is 45 minutes to 1 hour of driving by car. Public transport takes more time, around 2 hours and switching of lines is required.
