Mt. Fuji Climbing Season: What to Know Before You Go

Every summer, Japan’s most famous landmark, Mt. Fuji, draws thousands of climbers chasing the country’s highest point. For a few short weeks, the snow disappears, trails open, and the mountain turns from a postcard view into a real adventure.

Thinking about climbing it? Then timing is key. Knowing Mt. Fuji’s Japan official climbing season and a few safety basics will make your trip way better. Here’s what to know before setting foot on the mountain.

When is Mt. Fuji climbing season?

The official Mt. Fuji climbing season runs from early July to early September each year. It’s the only time when trails are open, huts are running, and first-aid stations are ready. During these summer weeks, the weather is the most stable, buses run to the 5th Station, and rescue teams are active if needed.

In early July, the Yamanashi side kicks things off, with the famous Yoshida Trail opening around the first of the month. By mid-July, the Shizuoka Prefecture routes, Gotemba, Subashiri, and Fujinomiya, join the action. When early September rolls in, huts start closing, the crowds thin out, and snow slowly returns to the peaks.

Once the season ends, climbing is not advisable. Trails are closed, huts are empty, and rescue services are limited. The weather becomes unpredictable, and temperatures at the top can drop below freezing even in autumn. It’s best to wait for summer when Mt. Fuji is ready for climbers again.

Why the Season is Limited

Mt. Fuji might look calm from far away, but don’t be fooled. The mountain’s weather changes fast and can be rough. At 3,776 meters high, it feels more like an alpine peak than a summer hike. Strong winds, thick fog, and sudden temperature drops can occur without warning, especially at higher elevations.

The summer climbing season keeps things safe and organized. Trails are clear, huts are open, and help is available if needed. Outside this window, the risks rise fast. You could face freezing temperatures, lose your way, or deal with altitude sickness.

Officials in Japan make it clear: climbing out of season isn’t for beginners. It’s only for trained mountaineers with winter gear and authentic experience. For everyone else, summer is the best and safest time to conquer Mt. Fuji.

Choosing a Trail

There are four main routes to reach the summit. Each offers a slightly different experience:

Yoshida Trail (Yamanashi Prefecture)

The most popular and beginner-friendly route, with many mountain huts and rest stations. It’s often the busiest but provides excellent views of the sunrise.

Subashiri Trail (Shizuoka Prefecture)

Begins in forested terrain and merges with Yoshida near the top. It’s less crowded and offers a quieter climb.

Gotemba Trail (Shizuoka Prefecture)

The longest and least developed route starts from a lower elevation. It’s suited for experienced hikers who prefer fewer crowds.

Fujinomiya Trail (Shizuoka Prefecture)

The shortest route to the summit is, but with steeper slopes. It’s popular among climbers seeking a faster ascent. Most climbers start from one of the 5th Stations, located about halfway up the mountain. These stations offer food, water, restrooms, and gear rentals, serving as the primary starting point for all routes.

Preparing for the Climb

Climbing Mt. Fuji isn’t just for pros; you can totally do it with some prep! It usually takes about five to seven hours to reach the top.

Getting down takes another three to five hours, so pace yourself! The higher you go, the thinner the air gets, and breathing feels tougher. And guess what? It can be over 20°C colder at the top than at the bottom!

Plan an overnight stay

Bullet climbing means trying to go up and down Mt. Fuji in one day, and it’s a big no-no. It’ll leave you exhausted and dizzy from the altitude. Instead, stay in a cozy mountain hut to rest and adjust. Then wake up early to catch that magical sunrise at the summit.

Pack appropriately

Pack layered clothes, it gets really cold after sunset. Bring a windproof jacket, gloves, hat, and solid hiking boots. Add a headlamp, rain gear, and about 1.5 liters of water. Don’t forget to bring energy snacks to keep your energy up.

Pace yourself

Take it slow and rest every 30 to 60 minutes. Altitude sickness can affect anyone, regardless of fitness level. Watch for headaches, dizziness, or nausea, all of which are warning signs. If it gets worse, head down right away.

Check the weather

Even in summer, the weather can flip fast. Afternoon storms and heavy rain can sometimes appear, so start early. Always check the latest weather and trail updates before heading out.

Entry Fees and Regulations

Since 2024, some trails have introduced a climbing fee of approximately 2,000 yen (around $ 13 USD). They also limit the number of people who can hike each day. The Yoshida Trail, for example, closes during certain hours to prevent crowding and risky night climbs. These rules help protect the environment and support local maintenance.

Your fee also supports conservation efforts to maintain Mt. Fuji’s ecosystem’s health. Climbers should submit a simple hiking plan and follow all posted rules and regulations. There’s no big trash system up there; pack out everything you bring.

When to Go

July to September is the prime climbing season on Mt. Fuji. The sweet spot is mid-July to early August for good weather and smaller crowds. Early July can still have leftover monsoon rain, so pack wisely.

Late August and September mean fewer people, but colder and windier days. Weekdays are calmer than weekends, so start midweek for better hut chances. Most climbers aim for goraiko, or the sunrise at the summit. Watching the first light over the clouds is pure magic, but freezing. Bring extra layers for the top.

Respecting the Mountain

Mt. Fuji isn’t just a national icon; it’s a sacred place. Climbers are asked to show respect and stay mindful. Keep your voice low, stick to marked trails, and leave no trace. Shrines near the summit celebrate the mountain’s spiritual side. Many hikers stop to give thanks before heading back down the trail.

Why the Mt. Fuji Climbing Season Matters

Climbing Mt. Fuji isn’t just about the summit; it’s about timing it right. The official season is July to September for a reason. During these weeks, trails are safe, maintained, and support services are running.

Outside that window, the mountain turns icy, unpredictable, and risky. Weather can change rapidly, and summit temperatures can drop below freezing, making rescues more challenging. Sticking to the season protects you and honors the mountain and its keepers.

Climb when Mt. Fuji magic welcomes you, take it slow, and soak in the views. Sunrise, clouds, and quiet summit moments make it more than a hike; it’s unforgettable.
