Ōwakudani


Ōwakudani is a volcanic valley with active sulphur vents and hot springs in Hakone, Kanagawa Prefecture, Japan. It was created around 3,000 years ago, as a result of the explosion of the Hakone volcano.
It is a popular tourist site for its scenic views, volcanic activity, and kuro-tamago — a local specialty of eggs hard-boiled in the hot springs. The eggs turn black and smell slightly sulphuric; eating one is said to add seven years to your life.
Upon seeing the hellish scenery, when Koubu Daishi visited Owakudani more than a thousand years ago, he offered prayer to Bodhisattva. The Enmei-jizo in Owakudani is said to have its origin in the prayer.

Access

Access to Ōwakudani is via a funitel, the Hakone Ropeway, or a bus line from Odawara Station, Hakone-Yumoto Station, Kowakidani Station / Kojiri, the Izuhakone Bus. There is a road to a visitor's center just below the Kuro-tamago hot springs site.
Most visitors used to hike the roughly trail or take the Hakone Ropeway to close to where the eggs are boiled to participate in the ritual egg eating. The funitel offers a vast view of Mount Fuji and the sulphur vents just below the visitor's center.
Present day activities surrounding sulphur vents are the result of massive land slides in the past. Construction of concrete barriers and stabilization of the area have been under way for decades.

Closure

The tourist site in Ōwakudani was closed in May 2015 due to volcanic activity. It re-opened on April 27, 2016, but not fully, as it is not possible to walk close to the steaming vents due to the hazards involved. People with asthma, bronchitis, heart disease, heart pacemakers, and pregnant women are advised not enter the valley because of high volcanic activity.
