The Zao Echo Line, which opens in late April, is a driving course where you can enjoy the changing scenery of the four seasons: snow corridor in spring, fresh greenery in summer, and autumn leaves in fall. The snow corridor is a powerful sight with walls of snow towering up to 9 meters high on both sides. In summer, visitors can enjoy forest bathing in the fresh greenery. In autumn, visitors can enjoy the gradual changing of the colors of the leaves from the top of the mountain. At the summit of the Zao Echo Line, together with the Zao High Line (toll road), there is an ogama (cauldron) where visitors can experience the great outdoors.
