Owakudani Valley is located in the city of Hakone in the southeast of Mount Fuji. It is the crater of the volcanic eruption that occurred at the end of the Hakone volcanic activity about 400,000 years ago. Also known as "Great Hell." In the Hakone surrounded by green trees, only the mountain rocks are exposed, and the geothermal vapor sprayed between the rock seams is misty. From the cracks in the open crust, a large amount of sulfur vapor is sprayed to boil the spring water. It makes people feel that the life movement of the earth is spectacular. This allows you to see the beautiful scenery of Mount Fuji and the Hakone Mountains. Hakone Owakudani continues to spray large amounts of water vapor and volcanic gas from the ground every day. Approaching the vicinity of Owakudani, you will smell the scent of sulfur in the volcano. The scenery of Mount Fuji from Owakudani is also spectacular.
