Mishima Ancient Fuji Lava
Mount Fuji formed its current shape through repeated eruptions about 100,000 years ago.
In particular, the eruption about 10,000 years ago is called the "Mishima Lava", which is said to have flowed for about 40 kilometers and filled the valleys of Mt. Ayo and Mt. Hakone.
The reason why it flows so widely is said to be that although the eruption is not violent, the lava flows like a river.
The usual Fuji lava is the lava that erupted in 1707, but if you think about it carefully, the Mishima lava can be said to be a precious lava that erupted a long time ago.
