Hidden Koboro Geosite and Special Access Hike through Toya-Usu UNESCO Global Geopark with Special Permission

• Koboro geosite around “Koboro Station,” one of Hokkaido's top three unexplored regions. We will guide you to the Koboro Cave and Iwatani Kannon as highlights. The Koboro Cave, which has been used by humans since the end of the Jomon period, is said to have been formed by the eruption of an undersea volcano about 3 million years ago. Inside the cave, Iwaya Kannon (headless Kannon), which is said to have been made by Enku Shonin in the early Edo period, is enshrined.
