Owakudani is one of Hakone’s most famous scenic spots, a volcanic valley formed by the eruption of Hakone Volcano about 3,000 years ago. With white steam rising from the ground and the scent of sulfur in the air, it is a place where visitors can feel the living power of the earth up close.
This area was not always called Owakudani. It was once known as “Jigokudani,” or “Hell Valley.” Because volcanic gas and acidic soil made it difficult for plants to grow, the landscape was barren, rocky, and severe. Its harsh appearance led people to see it as a hell-like place and gave rise to its earlier name.
In the 20th century, Owakudani began to attract attention as a tourist destination. The opening of the Hakone Ropeway in 1959, followed by the completion of the full line in 1960, helped establish Hakone as a major sightseeing and hot spring area. Owakudani then became one of its most iconic attractions, admired for its dramatic scenery and visited by around two million people each year.
Shibusawa Eiichi also played an important role in the development of the region. Known as the “father of Japanese capitalism,” he was involved in projects that supplied hot spring water from Owakudani to places such as Sengokuhara and Gora. His efforts helped support Hakone’s growth as one of Japan’s leading hot spring destinations.
If you visit Owakudani, be sure to try its famous black eggs. Cooked in the area’s mineral-rich hot spring water, their shells turn black through a chemical reaction. They are known for their rich flavor, distinctive aroma, and their connection to this unique volcanic landscape.
If you visit Japan, Owakudani is a place worth experiencing for yourself—a dramatic landscape shaped by volcanic power and once feared as a place of hell.
