Present-day Mount Fuji is a stratovolcano formed by the composite of three successive volcanoes. These three volcanoes are:
- Komitake: The oldest of the three, which forms the base of the mountain.
- Ko Fuji ("Old Fuji"): Which surmounted Komitake approximately 100,000 years ago.
- Shin Fuji ("New Fuji"): The most recent volcano, which became active about 10,000 years ago and created the mountain's current tapered form by filling in the slopes of its predecessors and adding the summit zone.1
