Tucked away in a massive prehistoric caldera just north of central Naruko, Onikōbe Onsen (鬼首温泉) offers a more rugged, alpine contrast to the traditional streetscapes of the village center. Known as the “wilder side” of the Naruko Onsen-kyo area, this highland retreat is a place where the earth’s raw power is on full display. From the dramatic plumes of the Benten Geyser to the sprawling marshes and steaming “Hell” valleys that dot the landscape, Onikōbe is a perfect side trip to Naruko Gorge. Whether you are soaking in an open-air bath with views of the Mount Kamuro peaks or exploring the artisanal history of the region’s mountain dwellers, Onikōbe provides a sense of isolation and natural grandeur that is increasingly rare. It is a place where the volcanic heat of the earth meets the cool, crisp air of the Tohoku highlands, creating a perfect year-round destination for hikers, skiers, and seekers of quietude alike.

Jigokudani Walking Trail (地獄谷遊歩道)
The Jigokudani (Hell Valley) Walking Trail offers a unique trekking experience through a rugged canyon where hot springs burst from the ground with a roar, creating a scene that truly lives up to its name. This trail offers a raw, powerful look at Japan’s volcanic nature, making it a standout “hidden gem” if you want to experience something more visceral than a typical forest walk.
Walking through the steam rising from over a dozen vents of all sizes, you will feel the magnificent hidden power of nature and the raw energy of the earth beneath your feet.
Please be careful not to touch the spring water, as it reaches scorching temperatures of around 80°C. The heat is put to good use near the “Murasaki Jigoku” (Purple Hell, 紫地獄) area, where visitors enjoy making their own soft-boiled “onsen eggs” using eggs brought from home.
- Effort Level: Easy to Moderate. The path follows the valley floor, but the ground can be uneven, damp, and slippery due to the constant steam and spray.
- Walking Time: A leisurely round trip takes about 30 to 40 minutes.
- Footwear: Because the trail is often wet from steam condensation, shoes with good traction (like the Salomon X Ultra model) are highly recommended.
- Winter Closure: Like most outdoor attractions in the region, it is also strictly closed during the heavy snow months (late November to late April).
- While in Japanese only, refer to HERE for a visual map of the Jigokudani Walking Trail.
The “Hellish” Atmosphere at Jigokudani Walking Trail
The name “Jigokudani” (Hell Valley) comes from the numerous steaming vents and bubbling hot springs scattered along the valley floor. As you walk, you are surrounded by the sound of hissing steam and the sight of thick white clouds rising from the earth.
- Volcanic Energy: There are over 10 active hot spring vents along the trail.
- Vibrant Contrast: In autumn, the combination of brilliant autumn leaves and ethereal white steam creates a dramatic, otherworldly landscape that is a favorite among photographers.
How to Get to Jigokudani Walking Trail
- Jigokudani Walking Trail is located in the Onikōbe area, about a 20-minute drive from Naruko-Onsen Station.
- From Naruko-Onsen Station (鳴子温泉駅), you can also take the Onikōbe Line (鬼首線) of Ōsaki City Bus(大崎市営バス) and get off at Kanketsusen-mae (かんけつ泉前). Then walk for 10 minutes to the trailhead.
- The bus trip takes around 40 minutes.
- There are only 6 services per direction. Refer to Ōsaki City’s website for the bus timetable.
Onikoube Geyser (鬼首かんけつ泉)
Since you have travelled to the Onikōbe area, you can combine the Jigokudani Walking Trail with a visit to the Onikōbe Geyser (Kanketsusen) nearby. The park features two distinct types of geysers that erupt at regular intervals, each with its own unique character:
- Benten (弁天): The Powerhouse
- Eruption Height: Sends a massive column of hot water up to 15 meters (approx. 50 feet) into the air.
- Interval: It erupts roughly every 10 minutes.
- Scientific Note: The eruption is caused by geothermal heat boiling groundwater trapped in underground cavities until the pressure forces it upward.
- Unryu (雲竜): The Gentle Giant
- Eruption Height: Reaches about 2 to 3 meters (7 to 10 feet).
- Interval: It erupts every 10 to 20 minutes.
- Scientific Note: This geyser operates through a vertical shaft where volcanic heat causes the underground water to surge and spill over the surface.
Tips:
☛ Bring a towel to dry your hands and feet after soaking them in the free, mineral-rich hand bath and foot bath while you watch the geysers in the park.
☛ Because the Benten geyser erupts so high, use a fast shutter speed (1/1000s or higher) to “freeze” the water droplets in mid-air against the backdrop of the autumn trees!

Named after the iconic symbol of the Onikōbe region, Mt. Kamuro (Kamuro-dake, 禿岳), this farm is a seasonal highlight for travelers exploring the area. Often overshadowed by the larger ski resort and campgrounds, it is a quintessential stop for those who want to taste the fruits of the volcanic soil.
