Formed roughly 3,000 years ago during an eruption of Mount Hakone, Owakudani—often translated as the 'Great Boiling Valley'—is a raw and captivating volcanic wonderland. Visitors can ride the scenic aerial ropeway across steamy ravines filled with bubbling hot springs and active sulfur vents, taking in magnificent views of Mount Fuji on clear days. A highlight of any trip is tasting kuro-tamago, ordinary chicken eggs turned jet-black from boiling in the mineral-rich geothermal waters, said by local folklore to add seven years to your life. It remains one of Japan's most visceral encounters with living geological forces.
