Climbing Mount Fuji During the Official Season: Everything You Need to Know

Climbing Mount Fuji is one of the most popular experiences for travelers visiting Japan, especially during the official climbing season.

However, this journey still requires careful preparation due to the natural conditions, weather changes, and safety regulations that must be followed.

When Does the Official Mount Fuji Climbing Season Open?

The official climbing season for Mount Fuji usually opens every year from early July to early September.

During this period, the hiking trails are considered safe because the snow has melted, facilities such as mountain huts and toilets are open, and weather conditions are relatively more stable for climbing.

In general, each climbing route on Mount Fuji has a slightly different opening schedule. For 2026, the schedules are as follows:

• Yoshida Trail & Subashiri Trail: Scheduled to open on July 1
• Fujinomiya Trail, Gotemba Trail & the Summit Trail (around the crater rim): Scheduled to open on July 10

However, keep in mind that opening dates may be postponed if snow-clearing operations are not completed in time.

Popular Mount Fuji Climbing Routes

Mount Fuji has four main climbing routes that all lead to the same summit, but each differs in difficulty level, scenery, and number of climbers.

Yoshida Trail

This is the most popular and crowded route.
It is suitable for beginner climbers because it has the most complete facilities, including many mountain huts and rest stations. This trail is also commonly chosen by climbers hoping to see the sunrise from the summit.

Fujinomiya Trail

This is the shortest route because its starting point is at the highest elevation.
The trail is relatively steep, but many climbers choose it because the climbing time is shorter compared to other routes.

Subashiri Trail

This route is quieter and begins through a beautiful forest area.
Near the upper section, the trail merges with the Yoshida Trail, so the final part of the climb becomes the same.

Gotemba Trail

This is the longest and least crowded route.
Because it starts from a lower elevation, the climb is more physically demanding and takes longer, making it more suitable for experienced climbers.
