Mount Fuji (Fuji-san) at 3,776 metres is Japan’s highest mountain and most enduring symbol — a near-perfect volcanic cone visible from Tokyo on clear days, revered in Shinto tradition, celebrated in art from Hokusai to the present, and ascended by approximately 300,000 climbers each year during the official summer season. Climbing Fuji is one of Japan’s most iconic physical experiences.
The Official Season
Mount Fuji’s official climbing season runs from early July to mid-September, when mountain huts are staffed, trails are maintained, and rescue services are deployed. Outside this window, trails lack facilities, weather is unpredictable, and the mountain authorities strongly discourage ascent. The notorious practice of bullet climbing (climbing overnight from the fifth station to summit and back in a single push) is discouraged due to altitude sickness risk; most climbers benefit from an overnight stay at a mountain hut around the eighth station.
Four Trails: The Yoshida Route
Four trails ascend Fuji from different directions. The Yoshida Trail (Kawaguchiko, north face) is the most popular, accounting for over half of all climbers — it has the most mountain huts, the most reliable facilities, and the most used descent path (Yoshida Descent is a sandy switchback separate from the ascent route). The Subashiri Trail (east face) has a forested lower section. The Gotemba Trail (southeast) is longest, least crowded, and most strenuous. The Fujinomiya Trail (south face) is the second most popular and reaches the summit fastest in distance, though its steepness is demanding.
Yoshida Trail: Station by Station
The Yoshida Trail begins at Fifth Station (2,305 m) — the road terminus accessible by bus from Kawaguchiko or Fujisan Station. Most day visitors go no higher; climbers begin their ascent from here. Sixth Station (2,390 m) is the last tree line. Seventh Station (multiple huts, 2,700-3,030 m) marks the serious climbing zone. Eighth Station (3,020-3,360 m) is where most climbers spend the night to acclimatise and time their summit arrival for sunrise. Ninth Station (3,600 m) is the last facility before the crater rim. The summit crater rim (3,720 m) can be circumnavigated in about 1 hour (Ohachi-meguri, crater walk). The true highest point, Kengamine, is accessible on this circuit.
Altitude Sickness & Physical Preparation
Acute mountain sickness (AMS) affects many climbers regardless of fitness level — the key variables are ascent speed and individual acclimatisation. Symptoms include headache, nausea, and fatigue. Ascend slowly, drink water consistently (one litre per four hours), and descend immediately if symptoms worsen. Most cases resolve with descent. Diamox (acetazolamide) can help but requires a prescription. Fitness level affects comfort but not AMS risk — a marathon runner can suffer altitude sickness while an unfit person does not.
What to Bring
Layers are critical: temperatures at the summit can be 15-20°C colder than the fifth station, and wind chill is severe even in August. Essentials: waterproof jacket and trousers, warm mid-layer, gloves, hat, headlamp with spare batteries (sunrise climbs start at midnight), trekking poles, water (2 litres minimum; water is sold on the mountain at 200-500 yen per bottle), high-energy snacks, and cash for mountain huts. Rental gear (jacket, pole, crampons for early season) is available at fifth station shops.
Fujiko: Fuji Worship Tradition
Fuji has been a Shinto sacred mountain for over 1,200 years. The Fujiko confraternities — religious associations that made collective pilgrimages to Fuji’s summit — were active from the 12th century. Sengen Taisha shrines at the mountain’s base and on the summit crater are dedicated to the deity Konohanasakuya-hime. Fuji was inscribed as a UNESCO World Heritage Cultural Site in 2013 — reflecting its cultural and artistic significance rather than its natural features. The 2024 season saw new crowd management measures including trail gates and entry fees (1,000 yen) on the Yoshida trail.
