Enjoy megaliths and natural vegetation along the 4 kilometers of spring, summer autumn and winter. The road along the valley from November to November is one way from the downstream (Tenjinmori) to the upper stream (Nohizumi) on weekdays passenger cars. Please note that weekends and national holidays will be pedestrian only. In the Tenjin Forest, there is a space for free parking of about 200 passenger cars.
