Mount Fuji itself reaches an incredible 3,776 meters in total. Japan is based in the Circum-Pacific – which is fondly referred to as the ‘Ring of Fire’. This means that Japan has a lot of mountains.

It also means that it is a country that may suffer from severe weather and natural occurrences. Some of these include tsunamis, typhoons, earthquakes, and maybe even a volcanic eruption.

Mount Fuji is a huge symbol of Japan. It has a beautiful form. You will find many shrines and temples located around this famous mountain.

When Did Mount Fuji Last Erupt?

The last eruption of Mount Fuji was in 1707. It is considered to be a major disaster of the time. This is because the eruption itself lasted for two whole weeks. Known as the Hoei Eruption, it released volcanic rock and ash into the areas below.

The scoria and pumice from the volcano reached Edo (now known as Tokyo). The city is over 100 km away from the mountain – so you can see how far it traveled. Whether a coincidence or not, there was a potential tell-tale sign of the eruption.

Forty nine days prior to the Mount Fuji eruption, the Kansai region suffered a major earthquake. Are they linked, or were they just two different natural phenomena that happened within a short space of time?

What Makes Up Mount Fuji?

Mount Fuji contains several different volcanoes which overlap each other. The two which are most known are called ‘Young Fuji (Shin Fuji) and ‘Old Fuji’ (Ko Fuji).

The last recorded eruption was over 300 years ago in 1707. Since its formation over 100,000, it has erupted on numerous occasions. This definitely makes you think.
