The window for climbing Mount Fuji, Japan’s highest peak, is limited to approximately two months each year, generally from early July to early September. Outside of the open season, all trails are closed to the public, so it is important to familiarize yourself with the season and the characteristics of each route before making any plans.This article introduces the features of each of the four routes, the rules common to all of them, and the preparations you should make before heading to the mountain. If you are planning a climb up Mount Fuji, we hope you find this guide useful.
1. Mount Fuji’s Climbing Season: Typically Early July to Early September
Mount Fuji’s climbing season generally runs from early July to early September. However, the exact open period varies by trail. The Yoshida Trail on the Yamanashi Prefecture side typically opens first, while the Subashiri, Gotemba, and Fujinomiya Trails on the Shizuoka Prefecture side usually open slightly later. The open season is not fixed each year and may shift depending on snowfall conditions and the progress of trail maintenance.
From mid-July onward, the number of climbers increases significantly. Trails become particularly crowded on weekends and during the Obon holiday period (Japan’s traditional mid-August holiday for honoring ancestors), and congestion near the summit and in the hours before sunrise can be expected. Since mountain huts and trails fill up during this time, it is important to check the latest trail opening information and crowd forecasts when planning your climb.
1-1. Outside the Open Season, Trails to the Summit Are Closed
Outside the open season, for safety reasons, the trails from the 5th Station (Gogome) — the midpoint staging area where most climbers begin their ascent — to the summit are closed. Members of the general public can only aim for the summit during the summer open season; outside of this period, facilities such as first-aid stations, mountain huts, and restrooms are also unavailable. Mount Fuji’s high elevation makes it particularly susceptible to strong winds, low temperatures, snow, and icy surfaces during the closed season, significantly increasing the risk of becoming stranded even for experienced climbers.
Note that the Fujinomiya Trail may allow access from the 5th Station to the 6th Station during a limited period, but the section to the summit remains closed. Do not enter the mountain carelessly — always confirm the open season before making any plans.
2. Climbing Season by Route
There are four main trails for climbing Mount Fuji, each with its own level of difficulty and characteristics. Below, we introduce the features and climbing season for each route.
2-1. Yoshida Trail
The Yoshida Trail is the most popular climbing route on Mount Fuji, starting from the Fuji Subaru Line 5th Station on the Yamanashi Prefecture side. The trail is generally open from around July 1 to September 10 and is considered relatively accessible among the four routes.
The ascent route is lined with mountain huts (simple lodging facilities found on Japanese mountain trails), making it user-friendly even for first-time climbers. However, there are very few mountain huts along the descent route, and the ascent and descent paths are separate, so care is required. Due to its popularity, this trail is prone to crowding, particularly on weekends and during the Obon holiday period, when congestion is especially likely.
2-2. Subashiri Trail
The Subashiri Trail runs from Subashiriguchi 5th Station on the Shizuoka Prefecture side to the summit.The trail is generally open from around July 10 to September 10. One of its defining features is a long section through forested terrain, which provides welcome shade from strong sunlight. The descent is also known for “Sunabashiri” (literally “sand running”), a thrilling stretch where climbers can dash down a slope of volcanic gravel.
While the trail offers a strong sense of being in nature, caution is needed in foggy conditions or at night, as it is easy to lose your way. Near the 8th Station, the Subashiri Trail merges with the Yoshida Trail, so take care not to miss the fork when descending. The difficulty is moderate, and this route offers both scenic views typical of Mount Fuji and a satisfying physical challenge.
2-3. Gotemba Trail
The Gotemba Trail starts from Gotemba New 5th Station on the Shizuoka Prefecture side and heads to the summit. The trail is generally open from around July 10 to September 10. Of the four routes, it attracts the fewest climbers, making it ideal for those seeking a quieter experience.
While the gradient itself is relatively gentle, the starting elevation is low, which means the total distance and elevation gain are substantial, demanding a high level of stamina. Mountain huts and restrooms are sparse, and when fog rolls in, there are fewer landmarks to guide the way, increasing the risk of getting lost. Overall, this is considered the most challenging of Mount Fuji’s four routes and is best suited to experienced hikers.
2-4. Fujinomiya Trail
The Fujinomiya Trail starts from Fujinomiyaguchi 5th Station on the Shizuoka Prefecture side and heads to the summit.The trail is generally open from around July 10 to September 10. As the highest-starting trail of the four routes, it offers a relatively short distance to the summit.
On the other hand, the overall gradient is steep and there are many rocky sections, requiring both physical fitness and careful footing. Since the ascent and descent follow the same path, the risk of getting lost is low, but the trail tends to become congested during busy periods. While it is possible to reach the summit in a shorter time, this route should not be chosen on ease alone — it is rated moderate to moderately difficult.
3. Rules Common to All Mount Fuji Routes (Entry Restriction Hours, Fees, and Reservations)

4. Essential Preparations for Climbing Mount Fuji
To enjoy a safe climb up Mount Fuji, thorough preparation is essential — from gathering the right gear to building up your physical fitness. Here, we introduce the preparations you should undertake before heading to the mountain.
4-1. Gathering the Necessary Equipment
For climbing Mount Fuji, it is important to prepare the necessary equipment in advance to handle sudden weather changes, strong winds, drops in temperature, and delays during the descent. In particular, rain gear, cold-weather clothing, a headlamp, and a map are considered essentials. Old shoes and lights may malfunction, so be sure to check their condition before setting off.
- Hiking boots: Sturdy hiking boots or trekking shoes with firm soles
- Rain gear: A two-piece set (jacket and trousers) of mountaineering rain wear
- Cold-weather clothing: Fleece jacket, gloves, hat, etc.
- Light: Headlamp with spare batteries
- Food and drink: 1–2 liters of water or more, snacks, energy bars, etc.
- Maps: Hiking map, compass
- Other: Backpack, quick-dry clothing, cash, garbage bags
4-2. Training for the Climb
In preparing for the climb, physical conditioning is just as important as equipment.Since Mount Fuji involves hours of continuous ascent and descent, it is important to build endurance, lower-body strength, and core stability.
In your daily routine, incorporating hill walking or stair climbing one to two times per week is effective for improving cardiovascular fitness. Combining this with exercises such as squats and planks to strengthen the legs and core will help reduce fatigue during the climb.
Before your actual climb, it is a good idea to practice on a lower-altitude mountain to get a feel for hiking with a pack on your back and to gauge your own fitness level. Gradually acclimatize your body at a pace that works for you.
Summary
Mount Fuji’s climbing season generally runs from early July to early September, and trails are closed outside of this open period. The four routes — Yoshida, Subashiri, Gotemba, and Fujinomiya — each differ in difficulty and characteristics, so it is important to choose the one that best matches your fitness level and goals.
Be sure to also check the rules in advance, including entry restriction hours and trail fees. To enjoy the climb safely, we recommend gathering appropriate gear such as rain wear and cold-weather clothing, as well as building up your physical fitness beforehand. Being well-prepared will make your Mount Fuji climbing experience all the more rewarding.
