Owakudani Valley

Japan's Hakone Owakudani Valley Owakudani is the most famous volcanic tourist attraction in Hakone. The mountain rocks are exposed here, and the geothermal steam and mist are emitted from the cracks in the rocks. A large amount of sulfur steam is ejected from the cracks in the earth's crust, boiling the spring water. Climb to the mountaintop and try the "black eggs" boiled in volcanic hot springs, which the Japanese say can extend your life by 7 years if you eat one.
