大内峠
From Otokoyama, Yozano Town ( near Yozanoumi Hospital ) take route 53 towards Omiya. It's uphill all the way until you turn left at the corner seen in the photo below and enter the Ouchi Pass road. This is a really nice road until Ichijikan Park for road cycling and there are almost no cars on it. The views of Amanohashidate are also fantastic.
