Hachibodai Observatory (Ichinomegata & Ninomegata)
八望台
A free viewpoint from which you can see the Ichinomegata and Ninomegata crater lakes and Togawa Bay at the same time. It showcases Oga's distinctive low-profile volcanic crater landscape.
Hachibodai lies in the northwest of the Oga Peninsula. Its open viewing platform lets visitors see the two circular crater lakes, Ichinomegata and Ninomegata, at once. These are low-profile maar craters, a rare landform in Japan, and Ichinomegata is known for its preserved annual sediment layers. The view also takes in Togawa Bay, Mount Kanpu, and the Sea of Japan. On clear days, Mount Honzan and Mount Shinzan are visible too. Admission is free, and drivers can park. It is about a 10-minute drive from Oga Aquarium GAO, making it a good short photo stop on a drive around the peninsula.
