Mount Fuji Climbing Guide: When to Go, Which Trail, What to Bring

Mount Fuji stands at 3,776 metres and straddles Yamanashi and Shizuoka prefectures. Anyone searching for how to climb it should know first that this is a real mountain walk, not a sightseeing stroll. No rock-climbing technique is needed, but cold, wind and altitude send under-prepared people back down all the time. This guide helps you decide when to go, which trail to take, what to prepare and what to know before booking a place to sleep.

Climbing season

Fuji is open for general climbing only in a short summer window, roughly early July to early September. Outside it there is snow and ice, conditions are dangerous, the huts are closed and the buses to the fifth stations do not run. Opening and closing dates differ by trail and change by year. Early in the season snow patches and cold can linger, and the middle of the season is the most crowded, especially around Japanese holidays. Afternoons often bring cloud or storms, which is why many climbers set off in the afternoon or evening to reach the summit by morning.

Trails

For a first-timer coming from Tokyo, the Yoshida Trail is the least complicated. It starts from the fifth station on the Fuji Subaru Line, reached by bus from Kawaguchiko, and in some periods by direct bus from Tokyo. Bus schedules and entry requirements change by year, so check before you plan.

Booking and rules

In recent years rules have been introduced to reduce crowding and improve safety, such as caps on climber numbers on some trails, a climbing fee, and a strong discouragement of bullet climbing, meaning rushing up overnight without resting. Details such as numbers, fees, booking channels and the times gates close can change every year, so do not rely on old information. Use the official sites of Yamanashi and Shizuoka prefectures and the website of the trail you intend to use.

Gear

• Hiking shoes already broken in, with a grippy sole; thin sneakers are a poor idea.
• A proper two-piece rain jacket and trousers that block wind; the summit is cold and windy even in summer.
• Mid and base layers such as fleece, a warm top, hat, gloves and spare socks.
• A headlamp with spare batteries, drinking water, high-energy snacks and coins for toilets that charge a fee.
• A bag to carry your rubbish down, since bins on the mountain are scarce, plus a power bank for your phone.

Where to sleep

The safest approach is to book a mountain hut to rest and adjust to altitude, then continue in the small hours to watch sunrise, known as goraiko. Huts offer shared sleeping space and basic meals; the service is simple and not hotel-like. Reserve in advance under each hut's rules and follow its cancellation terms strictly. If you prefer to stay in town, Kawaguchiko is a popular base for the Yoshida Trail, but allow for the travel time to the fifth station.

A one to two day plan

1. 1Day one: reach the fifth station and acclimatiseReach the fifth station by late morning or afternoon, spend a while adjusting to the height, eat, then walk up slowly to the hut you booked.
2. 2A short restSleep or rest for a few hours in the hut. It will not be deep sleep, but it leaves you better prepared than going straight up.
3. 3Day two: summit and descentSet off in the early hours to reach the top before first light; turn back if the weather turns, and allow time for a tiring, slippery descent.

Safety

Altitude sickness such as headache, nausea and dizziness is common; if symptoms worsen, descend at once rather than push on for the summit. Anyone with heart or lung conditions, or who does no exercise at all, should talk to a doctor first. Do not go if the forecast shows storms, strong wind or thick fog. Tell someone trustworthy your plan, and do not rely on a phone torch alone. Mobile data helps with checking the forecast and calling for help, and a Japan eSIM can cover that, though signal on the mountain may not be steady everywhere.
