Mount Fuji — Fujisan at 3,776 metres, Japan’s highest mountain and most universally recognised symbol — receives approximately 200,000 climbers each summer season. The climb is physically demanding and altitude-sensitive but requires no technical mountaineering skills: it is a very steep, sustained hike on loose volcanic scree. Preparation and timing are the difference between a miserable and a transcendent experience.
Climbing Season
Mount Fuji’s official climbing season runs from early July to mid-September, when mountain huts and trail facilities are staffed and open. Outside this window, trails above the 5th station are officially closed; winter ascents are dangerous and require crampons, ice axes and experienced mountaineering judgment.
The most popular summit timing is the overnight climb — departing the 5th station around 10:00–11:00 pm, climbing through the night and arriving at the summit for goraiko (sunrise). The summit at dawn, above cloud level on a clear morning, with the shadow of Fuji stretching hundreds of kilometres across the plains below, is one of Japan’s most extraordinary experiences.
The Four Trails
Yoshida Trail (Fuji Subaru Line 5th Station, Yamanashi side): The most popular route — approximately 70% of all climbers. Best infrastructure: most mountain huts, clearest waymarking, most rescue facilities. Also the most crowded. Accessible by bus from Kawaguchiko Station (55 minutes) or direct highway bus from Shinjuku (2.5 hours).
Subashiri Trail (Subashiri 5th Station, Shizuoka side): Less crowded than Yoshida, joins the Yoshida trail at the 8th station. The descent crosses a sand-and-ash slope offering particularly rapid descent (sunabashiri) in late season. Accessible by bus from Gotemba Station.
Gotemba Trail (Gotemba 5th Station, Shizuoka side): The lowest 5th station (1,440 m), making this the longest and most demanding route. Very few hikers, offering genuine solitude. Excellent sand descent in season.
Fujinomiya Trail (Fujinomiya 5th Station, Shizuoka side): The highest 5th station (2,400 m), making it the shortest route. Steep, rocky terrain. Popular with experienced Shizuoka-side visitors.
Essential Preparation
Altitude sickness affects visitors with no prior high-altitude experience at Fuji’s summit elevation. Prevention: spend 1–2 hours at the 5th station before beginning, climb at deliberate pace, rest frequently. Bring waterproof jacket and trousers, warm mid-layer, gloves and headlamp. Trekking poles reduce knee stress on descent significantly. Mountain huts serve hot food and drinks. Pre-booking a hut sleeping space (approximately ¥6,000–¥8,000 including dinner and breakfast) is strongly recommended for overnight climbers in peak season.
Recent Access Restrictions
From 2024, Yamanashi Prefecture implemented a gate on the Yoshida trail’s upper section, closing after 4:00 pm daily and limiting daily climbers to 4,000 on the Yoshida route. Confirm current gate hours and reservation requirements before planning, as overcrowding management regulations may evolve in subsequent seasons.
