17 eruptions of New Fuji have been recorded since 781. Many of the eruptions occurred in the Heian era, with 12 eruptions between 800 and 1083. Sometimes inactive periods between eruptions lasted for hundreds of years, as in the period between 1083 and 1511, when no eruptions were recorded for over 400 years. At present, there have been no eruptions since the Hoei eruption in 1707, around 300 years ago.
The Hōei eruption of Mount Fuji occurred in 1707 . Although it brought no lava flow, the Hoei eruption released a tremendous amount of volcanic ash, which spread over vast areas around the volcano, reaching even Edo almost 100 km from Mount Fuji. The volume of ash was estimated at about 800,000,000 m³. The eruption occurred in the south-west side of Mt.Fuji, and formed three new volcanic vents, named 1st, 2nd and 3rd Hōei vents. Mt.Fuji has not erupted since then.
However, in the year following the Hōei eruption, the Sakawa river flooded as a secondary disaster because of the sediment of volcanic ash. Volcanic sands fell and widely covered the cultivated fields east of Mt.Fuji. To recover the fields farmers cast volcanic products out to dumping-grounds and made sandpiles. The rain washed sandpiles from the dumping-grounds away to the rivers again and again and made some of the rivers shallower. Especially into the Sakawa river voluminous volcanic ash flew and made temporary dams here and there. The downpour of rain on August 7th and 8th of the year following the Hōei eruption caused an avalanche of volcanic ash and mud and broke the dams to flood over the Ashigara plain.
The volcano is currently classified as active with a low risk of eruption.

Mount Fuji positioned on Honshu Island, is the utmost mountain in Japan at 3,776.24 m (12,389 feet). An lively stratovolcano[5][6] that very last erupted in 1707–08, Mount Fuji lies about one hundred kilometres (60 mi) south-west of Tokyo, and may want to be considered from there on a sparkling day. Mount Fuji (Fuji-san, ??? in eastern) is the utmost volcano and maximum height in Japan and theory-about between the three Holy Mountains (alongside with Mount Tate and Mount Haku). Fuji is a perfect, pleasing stratovolcano about 60 miles south-west of Tokyo, with a really symmetrical structure making it into well known image of Japan and an significant element in eastern artwork. On twenty sixth October 1707, a sparkling eruption presented itself with a wide 8.4 value earthquake devastating Honshu island, suggested through a number of smaller earthquakes felt close to Mt Fuji. The eruption began on 16th December 1707 from a sparkling vent on the SE flank of the volcano erupting a sub-plinian column of ash and pumice, turning out to be basaltic lava fountaining after 6 hours into the eruption. on the first day of the eruption, seventy 2 houses and three Buddhist temples were destroyed in Subassiri city 10 km from the volcano. Ash fell all around the south Kanto ordinary, Tokyo, and on aspects of the NW Pacific ocean 280 km from the volcano. the completed volume erupted over 16 days develop into anticipated to 0.sixty 8 cubic km of magma. Violent explosions were recorded until eventually 25-27 December, beforehand the eruption calmed down and ended on 1st January 1708.
