The great Mount Fuji, also known as Fuji-san, has the highest peak among all the volcanoes in Japan. Standing at an elevation of 3776 meters, it holds great cultural and religious significance in Japanese history. 

Since the origin of the volcano took place after a series of eruptions, it holds a unique physical and chemical structure. The perfect symmetrical cone covered with snow is an ideal spot for nature lovers and photographers to capture its finest details. 

Being filled with layers of ash, lava, and gas over the course of multiple volcanic eruptions fuels its volcanic activity. Besides, Mount Fuji holds the title of being a World Heritage Site. It was recognised for having a deep artistic impact and cultural significance in the society

2. Mount Aso- Boasts Rich Volcanic Ash 

12 things you should know about the volcanoes in Japan 

Did you know Mount Aso holds the title of being home to one of the largest calderas in the world? A caldera is a type of crater or depression formed as a result of frequent eruptions. 

Since Aso is not a lone volcano, it supports more than four active volcanoes on its crater. Each of these peaks has a distinct eruption pattern contributing to the scenic beauty and lush foliage covering the extensive slopes.

Moreover, at the expense of the volcano’s rich ash deposits, the surrounding area has turned into fertile agricultural land. Besides, the minerals and nutrients present in the dense ash have nourishing properties and are good for retaining moisture. 

While Mount Aso is considered the most active among the volcanoes in Japan, it shows occasional volcanic activity. If you are lucky, then you might get a chance to witness the subtle steam and rumbling of an eruption up close. Since it is potentially dangerous, it is advised to follow security measures to avoid any uncertain hazards.

The most unique factor of this volcano that makes it a popular destination among tourists is its geothermal creations. These include hot springs, geysers, and vents that resulted from the high pressure and gas emissions in the region. 

These hot springs, or “onsen” in Japanese, are a natural phenomenon of a bathtub holding several medicinal and therapeutic properties. 

3. Sakurajima- Japan’s One of the Most Active Volcanoes

Planning to see the captivating beauty of the Sakurajima volcano? The volcano certainly has some fascinating features in its region.

The vibrant plumes emitting from the towering volcano enhance the beauty of the volcanic landscape. Moreover, another unique characteristic of this incredible volcano is the presence of volcanic lightning. This sensational aspect occurs when the static current produced during a series of eruptions collide with volcanic gases, high pressure, and other intense particles resulting in lightning flashes.

In addition to volcanic lightning and ashy plumes, the Sakurajima volcano is also responsible for the formation of new islands and secreting volcanic materials like tephra. The volcanic bombs and tephra refer to large lava rocks, ash, lapilli, and other fragments secreted out of the volcano.
