Major Eruption of Mount Fuji Begins

Mount Fuji erupted in December 1707, marking its last major volcanic activity. Following a long period of dormancy, the eruption produced significant ashfall that blanketed surrounding regions, affecting agriculture and air quality. The eruption lasted for several weeks, with the event largely witnessed from nearby settlements, where the populace recorded their observations. This natural phenomenon drew the attention of scholars and prompted discussions about volcanic activity in Japan.
