This is a dirt trail that follows the coastline from Furusato to Doze, and was opened in the Meiji Period. From the lookout point, you can see the beautiful islands of Kiino-Matsushima floating in the Kumano-nada Sea. In the Edo Period, Nokogiri-zaka, which is above the current Kaino Tunnel of the JR Kisei Main Line, was the route over the mountain, but it is no longer used due to the construction of the railway.

At 73 m above sea level, Ikkoku-toge Pass is a gentle pass covered with cedar and cypress trees. A Jizo statue stands at the northern trailhead, and there is a small pass also known as Hirakata-toge Pass on the southern side of the trailhead.

At Okimi-daira, with beautiful views and where pilgrims aiming for the Kumano Sanzan from Ise get their first view of the Kumano sea, there is a wooden board with a two-line poem written by Bokushi Suzuki, a travel writer of the Edo Period. From April to May azaleas bloom, adding a splash of brilliant color to the fresh green leaves.
