Climbing Mount Fuji: routes, season, and what it actually takes

Mount Fuji is Japan's highest point at 3,776 metres and, during its two-month official season, one of the world's most climbed mountains — around 300,000 people attempt the summit each year. This is not a subtle trail through untouched wilderness: it is a managed, fee-charging, frequently crowded ascent that is nonetheless genuinely challenging, starts in the dark, and ends at a crater rim that most climbers will remember for the rest of their lives. This guide is for anyone who has already decided to make the attempt and needs to plan it correctly — not those looking for a Fuji view from Hakone or Kawaguchiko, but those who want to arrive at the summit crater before sunrise and know exactly how to get there.

When you can climb Mount Fuji

The official 2026 climbing season runs from 1 July to 10 September. The Yoshida and Subashiri trails on the Yamanashi side open on 1 July; the Fujinomiya and Gotemba trails on the Shizuoka side open ten days later on 10 July. All four routes close on 10 September. Dates shift slightly year to year — check fujisan-climb.jp before booking.

Outside this window, the trails are not "not recommended" — they are genuinely dangerous. Huts close, rescue services are not on standby, and weather above 3,000 metres deteriorates rapidly after mid-September. Off-season attempts are for experienced alpine mountaineers with full winter equipment. Several people die attempting them every year.

All climbers in 2026 pay a ¥4,000 conservation and safety fee per person at the trailhead. On the Yoshida trail, a gate at the 5th station closes at 14:00 and does not reopen until 03:00 — anyone without a mountain hut reservation above the gate cannot pass after 14:00, and a daily cap of 4,000 climbers applies. The Shizuoka-side routes (Fujinomiya, Subashiri, Gotemba) require pre-registration via the FUJI NAVI app and completion of an online safety course before arriving at the trailhead.

The four routes, compared

Yoshida trail (Yamanashi) — busiest, most huts, best transit access

Trailhead: Fuji Subaru Line 5th Station, 2,305m. Official times: 6 hours 10 minutes ascending, 3 hours 35 minutes on the separate descent path.

The Yoshida trail has by far the most mountain huts, concentrated between the 7th and 8th stations, and the most direct bus connection from central Tokyo. It is also the most crowded route on the mountain — crowded enough that Yamanashi prefecture now caps daily climbers at 4,000 and enforces the afternoon gate restriction to manage flows. If you want the widest choice of accommodation above the snowline and the simplest transit from Tokyo, this is the route. If you want a quieter ascent, it is not.

Pick this if: you're departing from Tokyo, want the most hut options, or value having other climbers around you in the dark.

Fujinomiya trail (Shizuoka) — shortest, starts highest

Trailhead: Fujinomiya 5th Station, 2,400m (the highest starting point of any route). Official times: 5 hours 10 minutes ascending, 2 hours 40 minutes on the same shared path back down.

At 4.3km each way, Fujinomiya is the shortest route to the summit and the one favoured by climbers who want the full ascent without Yoshida's crowds or Gotemba's marathon distance. The shared up-down path means stepping aside for descenders, and there are fewer huts than Yoshida — but it's meaningfully quieter and the high starting altitude shortens the day considerably. Access from Tokyo requires a Shinkansen to Mishima, then a seasonal bus.

Pick this if: you want the shortest route, don't mind the Shinkansen approach, and prefer fewer crowds.

Subashiri trail (Shizuoka) — quieter, forested start

Trailhead: Subashiri 5th Station, 2,000m. Official times: 6 hours 25 minutes ascending, 3 hours 20 minutes descending.

Subashiri's lower starting point means the first section climbs through pine forest before reaching Fuji's open volcanic terrain — a gentler, more varied opening to the day than the other routes. Above the 8th station the trail merges with Yoshida, so you join the main flow for the final push. The descent diverges again through the forest. Access from Tokyo goes via Gotemba station and a seasonal bus, adding one extra transit step.

Pick this if: you want a quieter, more varied ascent and don't mind an extra transit connection from Tokyo.

Gotemba trail (Shizuoka) — longest, the Osunabashiri descent

Trailhead: Gotemba new 5th station, 1,440m (the lowest starting point of any route). Official times: 8 hours 40 minutes ascending, 3 hours 30 minutes descending.

The Gotemba trail demands the most of any route — 10.5km of ascent covering 2,300 metres of vertical gain. It is the quietest trail on the mountain and the one chosen by experienced hikers who want the full challenge. Its reward on the way down is the Osunabashiri: a long sandy section of the descent where climbers can half-run, half-ski down loose volcanic ash and cover ground quickly. The Osunabashiri is Fuji's most distinctive feature and the reason some people specifically choose this route. Not recommended as a first Fuji attempt.

Pick this if: you're an experienced hiker who wants the quietest, most demanding route and the Osunabashiri descent.

Mountain huts vs. the overnight push

Most Fuji climbers aim for a sunrise summit, and there are two ways to do it. The standard approach: take an afternoon bus to the 5th station, begin climbing, stop at a mountain hut on the 7th or 8th station for several hours of rest, then continue at around 1–2am to reach the crater rim before dawn. The alternative — the "bullet climb" — is to leave the 5th station in the evening and climb straight through the night without stopping, arriving at the summit exhausted and, frequently, altitude-sick.

Every experienced Fuji climber advises booking a hut. The rest lets your body begin acclimatising above 3,000 metres before the final push; you reach the summit in better physical shape; and you avoid the coldest, windiest hours at the most exposed section of the climb. The 2026 Yoshida trail gate restrictions have also made the bullet climb harder to execute — you need a hut booking to pass the afternoon gate regardless of your climbing plan.

Hut prices at the 7th and 8th stations have risen substantially in recent years. Budget ¥12,000–¥20,000 per person including dinner and breakfast, with peak-season weekend rates at the higher end. Most huts accept cash only. Reservations for the busiest weeks — mid-July through mid-August — sell out within days of the annual booking window opening in late April. Browse each hut's website from mid-April and book the moment reservations open.

Fitness, altitude, and what to actually expect

Fuji is not a technical climb. No ropes, no scrambling, no specialist equipment. But it is a sustained aerobic effort that starts in the dark, lasts 9–12 hours round trip depending on route and rest time, and finishes near 3,776 metres — well above the altitude where most people start to feel the effects of thin air.

Altitude sickness (headaches, nausea, dizziness, fatigue) becomes a real risk above 2,500 metres and is common above 3,000m. Spending a couple of hours at the 5th station before climbing — eating, hydrating, moving slowly — gives your body some adjustment time. Above that, pace is everything: climbing too fast is the single most reliable way to end a Fuji attempt on the descent instead of the summit. Aim for a steady pace with short rests every 30–40 minutes, and drink water consistently throughout the ascent.

Temperatures at the summit crater rim average a low of around 2°C in July and 4°C in August, but wind chill regularly pushes the felt temperature below freezing, and brief snow is possible even in August. Bring a warm mid-layer and a windproof shell regardless of the forecast. Wearing shorts and a T-shirt from the 5th station is a mistake that becomes obvious above the 8th.

In the context of Japan's broader hiking landscape, Fuji sits at the challenging end — comparable to a long mountain day in the Alps, not an afternoon forest walk. That said, thousands of people in ordinary physical condition complete the ascent every season. Preparation and pacing matter far more than peak fitness.

Getting to the 5th stations

Private vehicles are not permitted on the approach roads during the climbing season — all access is by bus. No advance JR Pass is needed for the buses, though the JR Pass covers the Shinkansen leg to Mishima and the JR Gotemba line. See the getting around guide for Japan public transport in general.

Practical tips

• Cash: Mountain huts and the summit crater shrine accept cash only. Carry at least ¥5,000–¥8,000 beyond your hut booking for food, hot drinks, toilet fees (¥200–¥300 per visit), and emergency supplies.
• Headlamp: Essential for any pre-dawn start. Bring spare batteries — cold drains them faster than usual.
• Layers: Base layer, warm mid-layer (fleece or down), and a wind and waterproof shell. Add gloves and a hat before the 8th station even in July.
• Trekking poles: Reduce knee strain significantly on the descent, especially on Gotemba. Available to hire at 5th stations if you don't want to travel with them.
• Register early: Shizuoka-side routes require completing the FUJI NAVI e-learning course and paying the ¥4,000 fee before arrival — do this the day before, not at the trailhead.

Nearby

The 5th stations are transit points, not destinations. Build your trip around a base in Kawaguchiko, Hakone, or Gotemba town, and combine the climb with lake views or an onsen recovery day.
