Your Comprehensive Guide to Mt. Fuji’s Geography

Yes, Mount Fuji is classified as an active volcano, although it is currently considered dormant. The last confirmed eruption occurred in December 1707.

The most recent confirmed eruption of Mount Fuji took place in December 1707.

Mount Fuji stands at an impressive 3,776.24 meters (12,389 feet) tall.

The time it takes to climb Mount Fuji depends on the chosen trail and your individual fitness level. Climbing times can range from 4 to 10 hours, with most routes taking between 5 and 9 hours to reach the summit.

Mount Fuji can be broadly divided into two sections — the base and the summit cone. The base encompasses the lower slopes of the mountain, including the iconic Fuji Five Lakes and surrounding national parks. The summit is the upper volcanic portion of the mountain, starting from the fifth station on each trail and leading up to the crater rim.

Geologists have identified four distinct phases of volcanic activity that contributed to Mount Fuji's formation. Firstly, the Sen-komitake, around 400,000 - 100,000 years ago, formed a hidden andesite core. Secondly, the Komitake-Fuji, which occurred around 300,000 - 100,000 years ago, added a layer of basalt, shaping the base. Then, the Ko-Fuji (Old Fuji) formed around 100,000 to 17,000 years ago, built the bulk of the mountain through alternating layers of lava and ash. Lastly, Shin-Fuji (New Fuji), the ongoing phase, that started 10,000 years ago, is responsible for the mountain's iconic symmetrical cone and the most recent eruption.

Mount Fuji boasts an exceptional topographic prominence of 3,776 meters (12,388 feet), signifying its complete independence from any surrounding mountains. This makes it a truly isolated and majestic peak.

The formation of Mount Fuji is a complex process that began around 400,000 years ago. However, the present-day form, shaped primarily by the last two phases, is estimated to be around 10,000 years old.

Mount Fuji is classified as a stratovolcano, also known as a composite volcano. These volcanoes are formed through the gradual accumulation of lava, ash, and volcanic debris from numerous eruptions over a long period.

The surrounding landscape of Mount Fuji is rich in diverse geographical features, including: Fuji Five Lakes, Fuji-Hakone-Izu National Park, and Hakone Caldera.

Yes, the four main trails leading up Mount Fuji – Yoshida, Subashiri, Fujinomiya, and Gotemba – are ancient natural routes used by pilgrims for centuries. While some minor modifications have been made for safety and accessibility, these trails retain their natural character.

The immense popularity of Mount Fuji as a tourist destination has brought both positive and negative impacts on its geography. Increased foot traffic can lead to erosion, littering, and strain on the mountain's natural resources. However, tourism also raises awareness for conservation efforts and contributes to funding for maintaining and protecting the mountain.

If you’re looking to be a responsible traveler, some ways through which you can help minimize your footprint on Mount Fuji are: Following designated trails and avoiding creating new paths, packing out all your trash and disposing of it properly, and using designated restrooms and respecting the natural environment. Be mindful of your noise levels and respect the tranquility of the mountain for fellow climbers and wildlife. By following these simple practices, you can help ensure the continued beauty and enjoyment of Mount Fuji for generations to come.
