Owakudani is a volcanic valley with active sulphur vents and hot springs located inside Fuji-Hakone-Izu National Park of Hakone in Kanagawa Prefecture. You can really sense volcanic activity from a safe distance and the site has been a sulphur mine and a source for the Onsen water that feeds many of the local hotels. It is a popular tourist site and kuro-tamago (黒卵, lit. "black egg") is 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.
When we visited the alert level was lowest at 1 but this area can experience many earthquakes and is sometimes shut due to the volcanic activity. It’s a great place to visit with your camera and to photograph some other worlds scenes.
