Climbing Mount Fuji: Season, Routes, Crowds, and Everything You Need to Know
Key Insight
Fuji's climbing season runs July to early September — the Yoshida route now has a ¥2,000 entry fee and 4,000-climber daily cap after overcrowding, with mountain huts bookable months ahead.
📖 Explanation
The Basics
Mount Fuji (富士山, Fujisan) is Japan's highest mountain at 3,776m and a UNESCO World Heritage Site. The official climbing season runs from early July to early September, when mountain huts on the trails are staffed and the summit weather is safest. Climbing outside this window is possible but dangerous and discouraged — the mountain huts are closed and trail conditions are unpredictable.
The Four Routes
Yoshida Trail (Most Popular)
Starts from Fuji Subaru Line 5th Station (2,305m), making it the most accessible. Approximately 6 hours up, 3–4 hours down. The majority of all Fuji climbers use this route. In response to severe overcrowding (4,000+ climbers per day at peak), Yamanashi Prefecture installed a gate in 2024 that closes at 4 PM and reopens at 3 AM, with a ¥2,000 per person entrance fee. A daily cap of 4,000 climbers is enforced. Pre-registration is now recommended.
Subashiri Trail
Starts from Subashiri 5th Station. Less crowded than Yoshida but joins the Yoshida route near the summit. Descent has a distinct sand-scree path that allows running descent.
Gotemba Trail (Hardest)
Lowest starting point (1,440m), longest route, fewest amenities. 8–10 hours up. Recommended only for experienced hikers.
Fujinomoto Trail (Quietest)
Shizuoka Prefecture side. Fewer crowds, closes earlier in the season. Good choice for experienced hikers wanting solitude.
What to Prepare
Layers: summit temperature in summer is 4–6°C even when Tokyo is 35°C. Waterproof jacket essential. Headlamp: most climbers start around midnight for sunrise summit — a quality headlamp is non-negotiable. Altitude sickness: above 2,500m, headache and nausea are common. Ascend slowly, hydrate, rest at 8th Station. Descend if symptoms worsen. Physical preparation: the climb does not require technical skill, but 3,000m of elevation gain demands reasonable fitness. Train with stair climbing in the weeks before.
❓ Frequently Asked Questions
- Can I climb Mount Fuji without a guide?
- Yes — Mount Fuji is a fully marked trail and guides are not required. The Yoshida route has staffed huts at each station selling food, water, and oxygen cans. However, guided climbs are recommended for those unfamiliar with mountain safety, as altitude sickness and sudden weather changes affect many first-time climbers.
- How do I get to the Yoshida 5th Station from Tokyo?
- Direct Fuji Liner highway buses run from Shinjuku Bus Terminal (4 buses daily, ~2.5 hours, ¥2,700 one-way). Alternatively, take the JR Fujikyu Railway to Fujisan Station then a local bus to the 5th Station. The Fujikyu Highland area near the base is worth combining with a Fuji day trip.
- Is it dangerous to climb Mount Fuji?
- The main risks are altitude sickness, hypothermia (sudden storms are possible even in July), and exhaustion-related injuries on the descent. The trail itself is well-marked and non-technical. Several climbers are evacuated annually — most cases are altitude sickness that could be avoided by ascending more slowly and hydrating properly.
- What is the best time to summit for sunrise?
- Depart the 5th Station around 10 PM – 11 PM to summit around 4:30–5:30 AM (sunrise, goraikō). Allow 6–7 hours for ascent. Mountain huts on the Yoshida route allow advance booking (highly recommended in August) for a mid-climb sleep — this reduces the brutal continuous night climb and improves summit timing.
