Japan’s Volcanoes: Potential Eruption Risks and Their Impacts


Japan, a country known for its seismic activity, is home to numerous volcanoes, some of which have the potential to erupt in the future. However, not all volcanoes pose the same level of risk. In this article, we’ll introduce some of Japan’s volcanoes in order of their likelihood of eruption and explore the potential consequences should an eruption occur.


Mount Fuji

Mount Fuji, the iconic symbol of Japan, has been dormant for centuries. Although the probability of an eruption is relatively low, if one were to occur, it could result in widespread ash fall, disrupting transportation, damaging crops, and impacting public health. The densely populated areas surrounding Mount Fuji could also face significant economic repercussions.

Mount Aso

Mount Aso, known for its massive caldera, has a history of large-scale eruptions despite its ongoing volcanic activity. If an eruption were to happen, the region could experience agricultural losses due to ash fall, exposure to dangerous volcanic gases, and direct damage from lava flows. The area’s appeal as a tourist destination might also be affected.

Mount Ontake

Mount Ontake, which claimed many lives during its 2014 eruption, harbors potential dangers beneath its beauty. Should another eruption occur, direct damage from volcanic projectiles and ash, as well as impacts on water quality and agriculture, can be expected. The eruption could also have consequences for tourists visiting the area to enjoy its natural wonders.


Sakurajima, one of Japan’s most active volcanoes, has the highest probability of eruption. A large-scale eruption would lead to significant ash fall in the surrounding areas, posing health risks and damaging crops. The need for emergency evacuations and the impact on the tourism industry cannot be overlooked.

Understanding the risks associated with volcanic eruptions and making appropriate preparations is crucial. Volcanoes, while beautiful, are also a part of nature that can sometimes pose threats. Continued monitoring and research by experts will help us benefit from these natural wonders while remaining prepared for potential hazards.
