What is a Geopark?
Hakone Geopark is a natural park that offers opportunities to experience, learn, and enjoy geological activities.
Visitors can discover the link that connects the local plants and animals as well as our own history and culture with the geographical characteristics created by Hakone Volcano.
Yugawara onsen (Yugawara hot springs) was sung from long ago in Manyoshu (the oldest Japanese anthology) and benefited from the Yugawara volcano which was part of the Hakone volcanic zone. Many distinguished writers and artists have visited here and was the stage of the February 26 incident at Kofuso. In this area you can feel the blessing of nature while experiencing it historic culture.

The majority of the shoreline of Manazuru was not created by sea erosion. In the past, stone was quarried from the Manazuru shoreline and you can see traces of the quarries in various areas of the shoreline (arrow holes).
The entrance to Hakone Geopark flourished as a castle town from the Sengoku (warring states) era. Odawara-jo Castle and Ishigakiyama ichiya-jo Castle that became the stage of history, used the lava from the activity of the Hakone volcano to make a stone wall and is an area where you can see usage of the geological resources and touch a part of Japan’s history of that era.
