Guide
Owakudani is a massive volcanic crater formed by a phreatic eruption of Mount Kamiyama (the highest peak in Hakone) approximately 3,000 years ago. Even today, white plumes of steam rise constantly from the ground, accompanied by the distinct scent of sulfur, allowing visitors to visually experience the raw energy of volcanic activity. As one of Hakone's most iconic scenic spots, it offers a breathtaking display of dynamic topography and natural artistry. A highlight for many travelers is the famous "Kuro-tamago" (Black Eggs), which are boiled using the natural heat from the volcanic hot springs.
This area is a historically significant site shaped by the intense volcanic activity of the Hakone mountain range. The terrain, created by the massive eruption 3,000 years ago, serves as a powerful testament to the wonders of nature. The area also holds spiritual significance; for example, the "Owakudani Enmei Jizo Son" temple stands amidst the rugged landscape, illustrating the long-standing connection between nature and local faith. The presence of such spiritual sites within a harsh volcanic environment creates a unique, contemplative atmosphere that blends natural power with human culture.
The most striking feature of Owakudani is the volcanic landscape characterized by rising steam and rugged, rocky surfaces. The view is truly awe-inspiring, whether you are observing it from the Hakone Ropeway or stepping off the station. Following a recent renewal in April 2025, the area around Owakudani Station now features "Chikyu no Tani" (Valley of the Earth), a new observation spot designed to help visitors observe the Earth's natural processes more closely. Additionally, the "Kuro-tamago" (Black Eggs), known for their striking dark shells and unique flavor, are a central part of the visitor experience.
While the volcanic scenery can be enjoyed year-round, the landscape's appearance changes with the seasons. On clear, sunny days, the contrast between the bright blue sky, the white steam plumes, and the surrounding mountains is exceptionally vivid, offering the best photo opportunities. The scenery also shifts depending on the time of day, as the angle of sunlight changes the color of the rocks and the density of the steam. Because the area can be prone to fog, visiting on a clear day is highly recommended for the best visibility.
Visiting Owakudani is a journey of natural observation and culinary delight. You can observe the unique volcanic terrain and steam vents through paths like the Owakudani Nature Study Path. A quintessential experience is tasting the Black Eggs, which are said to extend one's lifespan if eaten. The newly renovated areas also offer modern exhibits and viewpoints centered around the theme of Earth's energy.
Owakudani serves as a major hub for Hakone sightseeing. From here, you can easily travel toward Togendai or Gora using the Hakone Ropeway. The surrounding region is dotted with nature-rich parks, historic shrines and temples, and charming cafes with beautiful views, making it easy to plan a comprehensive Hakone sightseeing itinerary.
As Owakudani is an active volcanic zone, the terrain can be uneven with some steps; comfortable walking shoes are highly recommended. Please be aware that the scent of sulfur can be quite strong, which may be sensitive for some visitors. Payments can be made via cash or credit cards (such as Visa and MasterCard). While English signage is available, it is helpful to check details in advance. For photography, you are welcome to capture the scenery, but strictly do not enter any restricted or cordoned-off areas for your safety.
