How to Climb Mount Fuji

Mount Fuji is a 3,776-meter volcano west of Tokyo. Most independent travelers climb it in summer. In the 2026 season, the official window runs from early July through September 10. The upper trails close outside those dates. Climbers pay ¥4,000 per person for each climb on all four routes. The Yoshida trail on the north side caps daily entries at 4,000 and uses an advance-booking system. Gates on all routes close between 14:00 and 03:00, so a mountain hut is the practical way to climb through that window.

Each trail starts at a fifth station, the road-accessible parking and facilities area about halfway up the mountain. The climb is divided into ten stations in total, and the day’s hike begins at the fifth station. Most climbers reach the summit in one day from the fifth station, or they spend one night in a mountain hut and start again before dawn.

Climbing Season Dates

The Shizuoka Prefecture page for Mount Fuji gives the official season as early July through 10 September. Japan Guide describes the same window as the time when the trails and mountain facilities are open, the mountain is usually free of snow, the weather is milder, and the huts are open. Snow and trail conditions can shift the opening dates, so the official notice for the year you travel is the final word.

Demand peaks in the middle of the season. The busiest stretch runs from about 20 July through the end of August, with Obon in mid-August and weekends especially crowded. If you want a quieter climb, aim for early July or the first week of September.

Outside the season, the upper mountain is not safe to climb. The official Mount Fuji climbing site states that the mountain is closed for winter, and that snow, ice, and strong winds make climbing unsafe. Do not plan a winter or shoulder-season ascent without checking current conditions with the authorities.

The final day of the season has one unconfirmed detail. The Yoshida descent may stay open until the morning of 11 September, but check the official site before you plan a descent that day.

Choosing Among the Four Trails

The four trails start from different fifth stations. Yoshida begins at the Fuji Subaru Line 5th Station on the north side in Yamanashi Prefecture, and it is the easiest to reach from Kawaguchiko Station. Subashiri (east), Gotemba (southeast), and Fujinomiya (south) begin on the Shizuoka Prefecture side.

Yoshida suits first-time climbers who want the most facilities and the most company on the trail. Its timing depends on pace and conditions, so check Japan Guide for current trail details. The daily cap and the booking system apply only here, which means a Yoshida climb requires more planning than a Shizuoka-side climb.

Gotemba trades time for solitude. A long climb to the top means a late start from a low station, a long night, and a bigger chance of arriving at the summit after dark. Fujinomiya is the shortest route but the steepest, so it rewards a fit climber who wants a quick ascent and does not mind a demanding slope.

The Subashiri trail opens on July 1 or July 10 in 2026, so check the date on the Shizuoka Prefecture page before you choose a trail. The Ohachi-meguri crater rim walk, a loop around the summit crater, opens on July 10 in 2026 and runs through 10 September.

Entry Fees and Reservations

The entry fee is ¥4,000 per person for each climb on all four routes in the 2026 season. Yamanashi introduced a ¥2,000 fee in 2024, and Shizuoka aligned at ¥4,000 in 2025. Before that, the two prefectures charged different amounts. Authorities said the fee revenue would pay for emergency shelters along the path for volcanic eruptions and for trail maintenance. Check the current fee on the official climbing site before you travel.

The fee applies to each climb, not to each season. A climber who ascends twice pays twice, and the Shizuoka-side guidance says the same. On the Yoshida trail, climbers without a booking can pay on site as long as the daily cap has room, so a booked slot is the safer choice for a fixed date.

Booking a Yoshida slot

The Yamanashi booking system is optional, but it is the only way to be sure of a place on a given day. The system works as follows:

• Climbers who pay in advance scan a QR code at the trailhead on the day of the climb.
• The daily cap is 4,000 climbers, with 3,000 slots for advance bookings and 1,000 for same-day entries.
• Access stops once 4,000 climbers have passed the fifth station that day.
• One representative can process payments for up to 100 people in a group.

Confirm the rules for changing a booked date and for refunds at the time of booking, and keep a copy of the confirmation.

Pre-registering for Shizuoka-side trails

The Shizuoka-side trails use a pre-registration system. Climbers complete a study of the rules and manners for protecting the mountain and for climbing safely before they receive an entry pass. Pre-registration runs through the FUJI NAVI app. Climbers who skip pre-registration can pay the fee and complete the rules study at the fifth station, which takes time, so pre-register before you travel.

The Shizuoka routes are not reported as capped. The daily cap applies to the Yoshida trail.

Gate Hours and Overnight Rules

The gates close each night between 14:00 and 03:00. The Shizuoka Prefecture page ties entry during that window to a hut stay. The 2024 rules barred climbers without an overnight hut booking between 4 p.m. and 3 a.m.

Confirm with the official site whether a day hiker can pass the gate after 14:00 before you set out.

For practical purposes, a hut booking is the surest way through. The Kamaiwakan hut on the seventh station says a booking confirmation email lets guests pass the fifth station gate after 14:00. Plan for a hut stay on the first night of any climb that starts in the afternoon. Hikers who begin early in the morning and reach the summit before 14:00 are not covered by the same overnight rule, but that schedule leaves little room for delay on a mountain where weather can change quickly.

Mountain Huts and Booking

Mountain huts provide beds, meals, and a rest point before the summit push. Yoshida-route overnight stays require advance booking through each hut. Fujisan Miharashi at the Fuji Subaru 5th Station takes overnight guests only in July and August, and it requires a reservation. The hut operates from about mid-March to mid-December. Sato-goya is open all year and requires a reservation in winter. Satomidaira/Seikans?, at the sixth station, takes online bookings through Yamatan.

Kamaiwakan takes overnight reservations online only. Its booking window usually opens after Golden Week, the early-May holiday cluster in Japan. It accepts credit cards, with 3-D Secure verification required, and PayPay. The summit hut Ch?j? Fujikan does not accept booking by email, because email requests can lead to availability errors.

The table lists 2026 season rates. Confirm every rate with the hut before you book.

Older figures are much lower, including about ¥7,500 for two meals in a shared room and about ¥6,000 for room only. Those figures predate the recent increases, so do not use them for budgeting.

Huts add charges beyond the room rate. Resting indoors without staying, or eating your own food inside, costs about ¥300. Benches outside the huts are free. Dinners at most huts follow a curry-based menu, with vegetarian options at some. Kamaiwakan says its breakfast and snacks are sold at its shop and are not included in the rate, so pack extra food if you want to save money.

Altitude and Weather Risks

Altitude sickness is the main medical risk on Mount Fuji. Japan Guide says many climbers develop it because the body needs time to adjust to a rapid gain in height. Symptoms include headache, nausea, dizziness, shortness of breath, and fatigue. The guide recommends a slow pace, steady fluid intake, frequent short breaks, and an overnight stay near the seventh or eighth station. Small oxygen bottles are sold at the fifth station and in the huts. They help, but they do not replace going down. Descent is the only reliable treatment, so a climber with worsening symptoms should turn back and descend.

A U.S. military base safety briefing for Yokota, updated in 2023, recommends limiting caffeine and alcohol for 24 hours before the climb and getting at least 8 hours of sleep. The briefing also says anyone in good physical condition is suitable for the climb. Fit people can still develop altitude sickness, so the advice applies to everyone. Plan to drink at least 2 liters of water a day, as this guide recommends.

The weather is the second major risk. The official site says the temperature changes and wind effects on the mountain are very significant, and it calls adequate equipment and preparation essential. Global Summit Guide says the summit averages a few degrees above freezing and falls to around 0°C with wind chill. Plan for cold, wind, and rain even in July. Summer thunderstorms can form quickly, and fog can make it difficult to find the correct trail at junctions.

Gear and Helmets

The official site lists hiking boots, rain gear including a jacket and trousers, and cold-weather clothing as essential for the standard one-night, two-day climb. Hiking boots with ankle support matter most on the rocky, steep sections. Break in the boots before the climb, because blisters are one of the most common problems on the trail. Avoid buying new boots just before the trip, as this guide advises. A two-piece rain suit works better than a poncho, which the Yokota briefing advises against.

Pack warm layers, including an insulated jacket, a warm hat, and gloves, along with a headlamp and spare batteries. Sun protection matters during the day: a hat, sunglasses, long sleeves, and sunscreen. Trekking poles are available for rent, according to the Yokota briefing. Global Summit Guide notes that a headlamp is essential for the night climb, which starts after midnight for most climbers who want to see the sunrise.

Do not count on sneakers or sandals being allowed on the trail. Bring proper boots.

The Yokota briefing also urges climbers to bring a helmet, a dust mask, and goggles. It cites the 2014 eruption of Mount Ontake, which killed more than 60 people when it erupted without warning. The briefing says even a bicycle helmet is better than none. The briefing is advice, not a Japanese legal requirement, so treat the helmet as sensible protection.

Why Crowd Limits Exist

Climber numbers have fallen since the peak years. Environment ministry data put the number of climbers at 221,322 in 2023 and 204,316 in 2024. An estimate for the 2026 season puts the count at about 240,000 climbers between 1 July and 10 September, a rise of roughly 17 percent.

Authorities cite protecting lives as the main reason for the restrictions. They call the bullet climb, a rush to the summit without a hut stay, dangerous, and the overnight rules are meant to curb it. Officials have also cited overcrowding, pollution, and disruptive tourist behavior. A Shizuoka official said 200,000 hikers is still a very large number and that some restrictions are needed for safety.

The 2024 figures fell, but one 2026 estimate shows traffic rising despite the rules. Commentators disagree on the approach. One argues that capping numbers is the wrong instrument and that fees should rise in peak months instead. Another visible change is a screen erected in Fujikawaguchiko that blocks the classic view of the mountain. The screen was meant to reduce crowds at a popular photo spot, and one news report calls it a giant black screen.

For a traveler, the practical effect is that a Yoshida climb in mid-August requires a booking, a fixed time, and a hut stay, while a late-season climb on a less busy trail may be easier to arrange on short notice. Check the official fee and booking pages before you set a date, because the rules have changed almost every season since 2024.

What to Decide Before You Climb

• Book the hut before the trail: Entry is restricted from 14:00 to 03:00, and a confirmed hut stay is the main way to climb through that window.
• Pick the trail by the time and the crowds: Yoshida has the booking system and the most people. Gotemba is the longest and least crowded. Fujinomiya is the shortest and steepest.
• Budget ¥4,000 for each climb: The 2026 fee applies to every climb on every route, so a return climb costs twice as much.
• Descend at the first severe symptoms: Descent is the only reliable treatment for altitude sickness, and oxygen bottles only help while you go down.
• Pack boots, layers, and rain gear: The summit can fall to around 0°C with wind chill, and a helmet is strongly advised even though the law does not require one.
