Mt. Otsuji has an elevation of 1,361 m.
From its peak you can enjoy spectacular panoramic views of the summit of Mt. Oyama, as well as the surrounding mountain ranges!
To get to the main climbing route, head for the Nagaotoge Pass parking lot located about 5 km past the National Tateyama Youth Outdoor Learning Center. There are portable toilets at the parking lot.
Once you walk about 500 m from the parking lot you will find the entrance to the climbing route. It is marked with a sign that reads "Forest Road 9".
Besides the main climbing route, there are also a number of other routes for you to try.
