Mount Fuji ( Fuji-san) is the highest mountain in Japan. It straddles the boundary of Shizuoka and Yamanashi prefectures just west of Tokyo, from which it can be seen on a clear day. It is located near the Pacific coast of central Honshu.
Mount Fuji is a well-known symbol of Japan and is frequently depicted in art and photographs, as well as visited by sightseers and climbers.
Scientists have identified four distinct phases of volcanic activity in the formation of Mt. Fuji. The first phase, called Sen-komitake, is composed of an andesite core recently discovered deep within the mountain. Sen-komitake was followed by the "Komitake Fuji," a basalt layer believed to be formed several hundred thousand years ago. Approximately 100,000 years ago, "Old Fuji" was formed over the top of Komitake Fuji. The modern, "New Fuji" is believed to have formed over the top of Old Fuji by around 10,000 years ago.
The volcano is currently classified as active with a low risk of eruption. The last recorded eruption occurred in 1707 during the Edo period. At this time, a new crater, along with a second peak, named Hoei-zan after the era name, formed halfway down its side.
Mt. Fuji is at the place where the Eurasian Plate (or the Amurian Plate), the Okhotsk Plate, and the Philippine Plate meet. Those plates form the western part of Japan, the eastern part of Japan, and the Izu Peninsula respectively.
