Restrictions on entry into the Owakudani Area have been lifted since November 15, 2019 (Friday) and visitors can now enjoy walks outside the Owakudani Station. As this is expected to cause traffic congestion on the roads surrounding Owakudani, visitors coming by car are recommended to use the carparks at Togendai Station or Ubako Station. The Sounzan Station carpark is closed due to damages from Typhoon 19.
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.
Also, although it is rare, the volcanic gas may cause seizures such as asthma in highly sensitive persons (including pregnant women, newborns and toddlers), persons with an allergic constitution, etc, and elderly persons, so please consider carefully whether you wish to ride the ropeway.
