The viewpoint is situated on the Jumonjibaru plateau, a region geologically linked to the volcanic activity of the Tsurumi-dake and Garan-dake mountains.
The elevation of approximately 500 meters results in temperatures noticeably lower than those in the central Beppu coastal districts.
The area is an active launch point for paragliding enthusiasts, frequently visible from the observation deck during favorable wind conditions.
Jumonjibaru is part of the Aso-Kuju National Park's broader environmental scope, emphasizing local biodiversity and volcanic geography.
Jumonji Viewpoint serves as a high-altitude observation deck situated on the Jumonjibaru plateau, providing an expansive vantage point over Beppu City and Beppu Bay. The lookout area sits at an elevation of approximately 500 meters, offering views of the city's steam-filled skyline and the Kunisaki Peninsula. On clear days, the silhouette of Shikoku Island can be seen across the Bungo Channel. The site is a popular location for observing the city lights after dusk. It features paved walkways and designated parking areas. The plateau is also a designated site for recreational paragliding, which can often be observed from the viewpoint. The surrounding terrain is characterized by highland grasses that transition in color with the seasons.
