It is said that the path of the Onoyama mountain pass was part of the Nankaido in the late Heian period. It almost overlaps with the Kumano pilgrimage road or the road called Kishu Kaido. This route starts from the JR Yamanakadani station along the road now known as the Kumano Kodo, visiting both ancient and modern history spots such as the Oji (shrine)Ruins on the way. In the end of the route you will cross the Kinokawa River to the JR Hoshiya station.
