Climbing Mount Fuji requires precise timing, advance permit registration, and strict adherence to seasonal gate rules. The official Mt Fuji climbing season runs from early July to September 10, with exact opening dates varying slightly by route. Understanding these schedules and local regulations determines whether you reach the summit or get turned away at the 5th station gate.
Modern rules limit daily hiker numbers on the most popular path, ban overnight "bullet climbing" without a reservation, and mandate a climbing fee. Planning a successful ascent means booking mountain huts months in advance and picking the right route for your fitness level.
Official Climbing Season Dates
The mountain remains closed for the rest of the year due to heavy snow, freezing temperatures, and high winds. During the summer window, snow clears from the paths, mountain huts open, and public buses run regularly from Tokyo and surrounding transit hubs.
- Yoshida Trail (Yamanashi Prefecture): Opens July 1 and closes September 10. This path sees the highest volume of hikers and starts at the Subaru Line 5th Station.
- Subashiri Trail (Shizuoka Prefecture): Opens July 10 and closes September 10. It merges with the Yoshida trail near the 8th station.
- Fujinomiya Trail (Shizuoka Prefecture): Opens July 10 and closes September 10. This route offers the shortest physical distance to the summit, starting at the highest 5th station.
- Gotemba Trail (Shizuoka Prefecture): Opens July 10 and closes September 10. This is the longest and least crowded route, featuring a famous volcanic sand descent.
Choosing the right week within this window matters. Early July brings fewer hikers but more unstable weather as the rainy season wraps up. Late August offers quieter trails as school vacations end, while mid-August (especially the Obon holiday week) brings heavy congestion and packed mountain huts.

Trail Rules, Fees, and Access Restrictions
Local authorities enforce strict crowd-management policies to protect hikers and preserve the mountain environment. If you show up without understanding these rules, you won't make it past the trailhead.
The mandatory climbing fee is ¥4,000 per person across all four routes. On the Yoshida Trail, online reservations through Yamanashi Prefecture's booking portal are required alongside a daily cap of 4,000 hikers (excluding those with overnight hut reservations). The three Shizuoka routes use the Shizuoka Prefecture FUJI NAVI registration system, which includes a short safety e-learning module.
Bullet climbing—attempting to hike straight through the night from the 5th station to the summit without resting—is effectively prohibited. Trailhead gates on the Yoshida route close from 2:00 PM to 3:00 AM unless you hold a confirmed mountain hut reservation. This rule stops exhausted, sleep-deprived hikers from stumbling up the steep volcanic slopes in the dark without adequate recovery.
Choosing Your Route and Itinerary
Most hikers take two days to complete the climb. A standard overnight itinerary involves taking a bus from Shinjuku to the 5th station, hiking 4 to 6 hours to an 8th-station mountain hut, sleeping for a few hours, and waking up around 1:00 AM to catch the sunrise (goraiko) from the summit.
The Yoshida Trail
This route is the most popular choice for first-time visitors. Separate paths handle the ascent and descent, reducing bottlenecks. Facilities are plentiful, with numerous mountain huts offering simple meals and basic sleeping spaces.
The Fujinomiya Trail
Starting at an elevation of 2,400 meters, this is the shortest route to the peak. Because the ascent and descent use the same path, traffic moves slower during peak hours. The rocky volcanic terrain requires careful foot placement.
The Gotemba and Subashiri Trails
These quieter routes suit experienced hikers seeking solitude. The Gotemba trail features the sunashiri—a wide, loose volcanic ash slope where hikers can practically ski down on foot, covering large vertical drops in minutes.
Essential Gear and Preparation
Don't let the summer season fool you. Summit temperatures regularly hover around freezing, even in August, and gale-force winds are common. Rangers at the 5th station check gear and may deny entry if you lack proper equipment.
- Layered Clothing: Pack a fleece, a thermal base layer, and a heavy down jacket. Cotton garments trap sweat and cause rapid chilling when you stop moving.
- Waterproof Shell: A sturdy two-piece rain jacket and rain pants are mandatory. Sudden afternoon thunderstorms and dense cloud cover can soak hikers within minutes.
- Footwear: Sturdy, broken-in trekking boots with ankle support are essential. Sneakers or running shoes offer zero protection against sharp volcanic gravel and fail mandatory gear checks.
- Cash and Supplies: Bring 2 to 3 liters of water and high-energy snacks. Mountain huts sell bottled water and canned oxygen, but prices increase with altitude, and they do not accept credit cards.

Frequently Asked Questions
Can I climb Mt Fuji without a reservation?
You can access Shizuoka trails or daytime slots on the Yoshida trail without advance booking if daily caps aren't reached, but peak dates sell out months ahead. Securing your permit online before traveling eliminates the risk of being turned away at the gate.
Do I need a mountain guide?
You don't need a guide if you possess basic hiking fitness, common sense, and the ability to read trail markers. The routes are clearly marked during the climbing season, though booking a guided group helps if you prefer logistics handled by professionals.
What happens if the weather turns bad?
Typhoons or severe high-altitude windstorms occasionally force officials to close the trails mid-season. Check local weather forecasts from the Japan Meteorological Agency before heading to the mountain, and build a flexible buffer day into your travel itinerary.
Are there luggage storage facilities at the 5th stations?
Yes, most major 5th stations provide coin lockers or luggage-holding services so you can leave your heavy suitcases behind while you tackle the summit trail with a lightweight daypack.
