touge is the mountain runs where one car follows another - and basically to determine who wins, they calculate the gap between the 2 cars. If the gap is increased, the front car wins, if its decreased, the back car wins. Best motoring had some good touge battles...tsuchiya, orido and all those people doing what they do best.
But yeah, there are some nice roads up north, but last time i went, there was road works, so becareful up there. Good twists, but due to the road works, it was very narrow.
