Senjojiki is a natural plateau located 333 meters above sea level on the Kawayama mountainside in Nagato, Yamaguchi Prefecture. The site provides panoramic views of the Sea of Japan and the islands of the Hibiki-nada sea. It is characterized by its expansive, gently sloping grassy hillsides. The area is officially designated as a camping ground and open space for public recreation. Visitors can observe the coastline's distinct geography, including the nearby Kawaradani cliff formations. It is accessible by vehicle via mountain roads leading up from the coastal Hekinaka district.
