Yes, October is one of the best months to see Mt. Fuji, as the transition to cooler, drier autumn weather significantly improves visibility compared to the hazy summer months. Statistically, the chance of a "clear-peak" day in October is approximately 57%, a major jump from the 15-20% visibility seen in June and July. While the clearest views are still in winter (December and January), October offers the added beauty of autumn foliage (Koyo) beginning to frame the mountain, especially toward the end of the month. It is important to note that the iconic "snow cap" on the summit typically returns in late October, so an early-month visit might feature a "naked" brown peak. To maximize your chances, aim for a dawn or early morning viewing at Lake Kawaguchi, as afternoon convection clouds often build up around the slopes by 11:00 AM. While typhoons can occasionally bring rain and clouds in September, by mid-October, the skies have usually stabilized, providing sharp, high-contrast views of the volcano.
