Overview
Owakudani is a volcanic valley created during the last eruption of Mount Hakone approximately 3,000 years ago. Billowing sulfurous steam vents, bubbling hot springs, and the desolate, barren landscape create a dramatic otherworldly scene.
Highlights
- Black Eggs (Kuro-tamago): Eggs boiled in the 80°C sulfurous hot springs, their shells turned jet-black by the minerals. Legend says each one adds seven years to your life.
- Fuji Views: On clear days, the volcanic plateau offers one of Hakone's most dramatic angles of Mount Fuji rising above the caldera rim.
- Volcanic Steam Vents: Walk along the boardwalk through active fumaroles where sulfurous gases billow from the earth, a reminder of Hakone's geological volatility.
History
Originally called Jigokudani (Valley of Hell) due to its hellish volcanic landscape, the name was changed to Owakudani (Great Boiling Valley) before a visit by Emperor Meiji in 1873 to avoid the negative connotation. Volcanic activity remains closely monitored.
Visitor Tips
- Air Quality: On high-sulfur days, visitors with respiratory conditions should check conditions before going. Access is occasionally restricted.
- Ropeway: The most scenic approach is via the Hakone Ropeway, which passes directly over the steaming valley.
- Duration: 1–1.5 hours.
