This route takes about 2.5 hours to traverse. While it is of a greater difficulty than the frontal route on the mountain, it looks out onto numerous natural foret groves and feels bright and uplifting. Proceed past the Eco Line and through the east hiking trail towards Mount Yufu. Reach the Beppu and Oita area at a higher elevation and look out onto beautiful scenery. Note that, while this route offers great views, it has craggy routes and poor footing in some areas. From the mountaintop, you can gaze out at Mount Tsurumi, Beppu Bay, the Kunisaki Peninsula, Oita, and Mount Kuju.
