All Months
July through September is your only realistic window for climbing, with August being peak season. Early July offers cooler temperatures and fewer crowds, but some huts might not be fully operational. Late July to mid-August brings the warmest weather and clearest skies, but also the biggest crowds—expect conga lines on the Yoshida Trail. September is the sweet spot: fewer people, stable weather, and autumn colors starting to show in the lower elevations. Avoid weekends if possible. The mountain sees 300,000 climbers annually, with 80% arriving on weekends. For viewing Fuji without climbing, spring offers cherry blossoms in the foreground, while winter provides the clearest views from the Fuji Five Lakes region.
