how old is mount fuji

Mount Fuji is estimated to have formed during the past 2.6 million years, with the current mountain being a composite of three successive volcanoes. The earliest volcanic activity probably started sometime after 700,000 years ago. The present-day stratovolcano, as it stands now, began forming around 100,000 years ago and took its nearly perfect cone shape roughly 10,000 years ago. The most recent volcanic activity (Shin Fuji or "New Fuji") started around 10,000 years ago and has continued intermittently since then.
