How did the 1707 eruption of Mount Fuji affect Edo?

During the 1707 eruption of Mount Fuji, the impact on Edo (modern-day Tokyo) was significant despite the city's distance from the volcano. Historical accounts indicate that the volcanic ash ejected during the event was heavy enough to darken the midday sky over the city.1

While the most severe destruction, including the burial of dwellings and temples, occurred in the immediate vicinity of the mountain, the ashfall reached as far as Edo, serving as a stark reminder of the volcano's power during that period.1
