These are the eruption traces of the Kamiyama crater,
which was made during the last explosion of the Hakone volcano about 3000 years ago.
White smoke has been laid on the desolate ground, and you can still feel the power of volcanic activity.

Filling power wrapped in magificent nature
The view of Owakudani as seen from the observatory gets powerful full marks. The desolate mountain skin and the rolling plumes of smoke create a unique landscape that will convince you of the area which was once called Jigokudani. There are lots of landscape spots while on the ropeway. You can see the view of the valley floor spreading under your eyes on the way from Sounzan to Owakuani, and you can enjoy the scenery of Mount Fuji and Lake Ashi on the way to Togendai.
On a clear and sunny day, you can see beautifully magnificent Mt. Fuji from Owakudani and the ropeway
Scenery from the ropeway
Between Sounzan and Owakudani, ther eis a place that crosses a valley about 130m form the ground, and you can see a powerful valley bottom widening underneath you.
If you get on the ropeway headed for Togendai in the evening, you can overlook the glittering lake surface of Lake Ashi.
Learn the charm and wonders of the Hakone Volcano!
A volcano where plumes continue to rise even now
Owakudani, where smoke containing hydrogen sulfide rises here and there even now. As a result, trees die, rock becomes clay and reddish mountain skin becomes visible. You can observe the dynamic activity of the volcano such as boiling water cauldrons and fumarolic gas blowing up white smoke. Another characteristic of Owakudani is that plants with stronger acidity can be seen as they are closer to the plume.
Hakone Volcano lives even now
Owakudani has explosion crater traces due to the eruption of the Hakone Volcano, and even now it spouts out sulfur and water vapor around 100℃.
The formation of the Hakone Volcano
With repeated eruptions that occurred from around 200,000 years ago to 80-60,000 years ago, it gradually became the shape it is now.
An explosion occurred in the Hakone Volcano about 3,000 years ago, and Owakudani and Lake Ashinoko were formed by the explosion of Kamiyama.
The former “Daijigoku” and “Kojigoku” were renamed
Owakudani was once called “Daijigoku (Great Hell)”, but before the visi of the Emperor and Empress Meiji on August 5, 1873 (Meiji 6), it was renamed to its current name of “Owakudani". At the same time, the fumarolic area called “Kojigoku (Small Hell)”, which was in contact with Kamiyama and Komagatake, was also renamed to “Kowakudani”.
About volcanic gas
The main components of the volcanic gas are water vapor, carbon dioxide, and also sulfur dioxide (sulfurous acid gas). Usually small amounts of hydrogen gas, carbon monoxide, hydrogen sulfide, and hydrogen chloride are present. Some volcanoes may include hydrogen fluoride, silicon tetrafluoride, methane, ammonia, carbonyl sulfide, helium, radon, and mercury vapor, etc. These gases can cause great harm to animals and plants due to the toxic components and oxygen deficiency, and in many cases there is a large influence on the surrounding ecology due to the heat. At Hakone Ropeway, we constantly measure the gas concentration and operate in a way that ensures that our customers can enjoy the ropeway in safety.
Cautions and safety measures
Due to the influence of the volcanic gases, the ropeway is dangerous for the following types of customers, so they cannot board the ropeway between Sounzan Station and Ubako Station. Depending on the concentration of the volcanic gases, operation may be suspended on all lines.
- Persons with allergic asthma
- Persons with bronchial disease
- Persons with respiratory (pulmonary) disease
- Persons with heart disease
- Persons wearing a cardiac pacemaker
- Persons in poor physical condition
Also, although it is rare, the volcanic gas may cause seizures such as asthma in highly sensitive persons (including pregnant women, newborn infants and infants), persons with an allergic constitution, etc, and elderly persons, so please consider carefully whether you wish to ride the ropeway.
For customers who board the ropeway between Sounzan Station, Owakudani Station, and Ubako Station, we have prepared the following:
