This course, circling clockwise around the government buildings and skyscrapers in the center of Nagoya City, takes you on an up-and-down roller coaster ride.
With long straights and high visibility, you can be sure it's a high-speed area.

Although the course diagram make it look like a long simple oval, the course is actually a high-speed area packed with corners, undulating roads, banks and altitude changes that mean you'll need superb machine control.
You may be tempted to up the power settings for the long straights, but your speed out of corners will affect your overall time. You'll need to get a good handling balance to master this course.
