help Owakudani Mudpots FAQ

Where are the Owakudani mudpots located?

The Owakudani mudpots are active geothermal features situated in the Hakone region of Kanagawa Prefecture, Japan. The area sits inside an ancient volcanic caldera formed by an eruption over 3,000 years ago.

Why does Owakudani smell like sulfur?

The intense sulfuric steam and vibrant mineral deposits are caused by volcanic heat rising deep from within the earth. As the magma heats groundwater, the resulting steam picks up sulfur gases, creating the distinct rotten-egg smell characteristic of the area.

What is the famous local snack cooked in the Owakudani mudpots?

The area is famous for "Kuro-tamago," or black eggs, which are chicken eggs hard-boiled in the hot sulfuric pools. The chemical reaction turns the eggshells completely black, and local legend says eating one adds seven years to your life.

Is Owakudani safe to visit during volcanic activity?

Access to Owakudani is heavily monitored by the Japan Meteorological Agency due to its active volcanic nature. During times of elevated sulfur gas emissions or seismic activity, walking trails and ropeway stations are often temporarily closed to protect visitors.
