Hiking Mount Fuji: everything you need to know
Mount Fuji is Japan's highest mountain and its most recognisable landmark, a near-perfect volcanic cone that rises to 3,776 metres south-west of Tokyo. Reaching the summit is a genuine goal for many visitors, and while it takes no technical climbing skill, it does demand respect, preparation, and the right timing. This guide covers what to expect on the mountain and how to plan a safe ascent.

| Best season | Early July to early September |
| Start point | A fifth-station trailhead, reached from Tokyo or Fujinomiya |

The climb is a long, steady uphill slog at altitude rather than a scramble, but the thin air, loose volcanic gravel, and fast-changing weather make it harder than the distance suggests.
Overview
Fuji is climbed almost entirely during a short official summer season, when the trails, mountain huts, and first-aid stations are open and staffed. Outside that window the mountain is genuinely dangerous, with snow, ice, and no support, and the authorities strongly discourage off-season attempts.
There are four main routes to the summit: the Yoshida Trail on the north side, the most popular and best-served by huts, along with the Subashiri, Gotemba, and Fujinomiya trails. Most climbers start from a fifth station partway up the mountain, where the paved road ends and the walking begins. The UK travel advice for Japan is at the normal level, but mountain conditions are their own risk, so treat Fuji as a serious hike regardless of the general picture.
A trail reservation and entry system now applies to the busiest routes in the climbing season, and rules change year to year. Check the official Mount Fuji climbing site for the current season dates, reservations, and any daily limits before you plan your dates.
Getting there
The Yoshida Trail begins at the Fuji Subaru Line Fifth Station, reached by direct bus from central Tokyo or from the towns around the Fuji Five Lakes. It is the easiest trailhead to reach on public transport and the busiest. The Fujinomiya Fifth Station, on the southern side, is the closest start point to the summit and is served from the Shizuoka side.

Best time to go
The official climbing season runs from early July to early September, and this is the only period most people should consider. July can still see lingering weather on the upper slopes, while late August tends to be more settled. Weekends and the mid-August holiday period are extremely busy, so a weekday climb is calmer.
Many climbers time their ascent to reach the summit for sunrise, known as goraiko. This usually means either climbing through the night or, more safely, staying in a mountain hut partway up and setting off in the very early hours.
The four trails
Four routes climb Mount Fuji, each starting from its own fifth station and each with a different character. Choosing between them is the main planning decision after choosing your dates.
Yoshida Trail. The northern route from the Fuji Subaru Line Fifth Station, and by a wide margin the most used. It has the greatest concentration of mountain huts and first aid points, and separate ascent and descent paths for much of its length. It is the default choice for a first climb, and the busiest.
Fujinomiya Trail. The southern route, starting from the highest fifth station of the four and therefore the shortest ascent to the summit. It is steeper as a result, and the same path serves both directions, so expect two-way traffic.
Subashiri Trail. The eastern route, quieter than Yoshida and wooded through its lower sections before it breaks out above the treeline. It merges with the Yoshida Trail higher up. The descent includes long stretches of volcanic gravel.
Gotemba Trail. The longest and least travelled route, beginning from the lowest fifth station. It has the fewest huts and the greatest height gain, and is generally treated as a route for climbers who already have mountain experience.
Trail and hut status is set each year by the local prefectures, and access arrangements have been revised more than once in recent seasons. Check the current official trail information before committing to a route.
What to bring
Conditions on Fuji can shift from warm sunshine to cold rain and strong wind within an hour, and the summit is far colder than the base. Pack for that range.
- Warm, windproof, and waterproof layers, including hat and gloves
- Sturdy walking boots with good grip for loose gravel
- A head torch with spare batteries for a night or pre-dawn climb
- Plenty of water and high-energy food
- A small amount of cash for huts, toilets, and rest stops
- Sun protection, as there is little shade above the tree line
- A basic first-aid kit and any personal medication
Altitude sickness is the most common problem on Fuji. Climbing slowly, resting at the huts, and spending time acclimatising near the fifth station before ascending all reduce the risk. If symptoms worsen, the only reliable treatment is to descend.
Visa and entry
British passport holders can enter Japan visa-free for tourism for up to 90 days, so a Fuji trip within a normal holiday needs no advance visa. Requirements depend on your nationality, so check our Japan entry requirements guide and confirm the rule for your own passport before you travel.
Getting connected on the mountain
Mobile coverage on Fuji is patchy but present on the popular trails, and having data matters for weather updates, hut bookings, and staying in touch with your group. A Saily eSIM lets you set up a Japan data plan before you fly and switch it on when you land, so you are connected before you even reach the trailhead.
Sort your Japan eSIM with Saily ahead of the trip, and see our best eSIM for Japan guide for setup and device compatibility.

Frequently asked questions
Do you need to be fit to climb Mount Fuji?
You need a reasonable level of general fitness and stamina, as the climb is a long uphill effort at altitude, but no technical climbing skill is required. Regular walkers who prepare properly and pace themselves can reach the summit.
How long does it take to climb Mount Fuji?
Most people take between five and seven hours to ascend and three to five to come down, depending on the trail and their pace. Splitting the climb across two days with a night in a mountain hut is the most common and comfortable approach.
When can you climb Mount Fuji?
The official climbing season runs from early July to early September, when the trails and huts are open and staffed. Climbing outside this window is strongly discouraged because of snow, ice, and the absence of any support on the mountain.
Do you need to book to climb Mount Fuji?
A trail reservation and entry system now applies to the busiest routes, and the rules change from year to year. Check the official Mount Fuji climbing site for the current season's reservation requirements and any daily limits before you set your dates.
Can beginners climb Mount Fuji?
Yes, many first-time hikers climb Fuji successfully, but it should not be underestimated. Beginners should go with realistic expectations, allow time to acclimatise, climb slowly, and be ready to turn back if the weather or altitude becomes a problem.
What is goraiko on Mount Fuji?
Goraiko is the sunrise seen from near the summit, a highlight for many climbers. Reaching the top in time usually means staying overnight in a mountain hut and setting off in the early hours, rather than climbing straight through without rest.
How cold is it at the summit of Mount Fuji?
The summit is far colder than the base and can be near freezing even in summer, made worse by wind. Warm, windproof, and waterproof layers are essential no matter how mild the weather looks at the fifth station.
Is it worth climbing Mount Fuji or just viewing it?
That depends on what you want. The climb is a memorable challenge with a sunrise reward, but it is hard work and often crowded. If you prefer scenery without the effort, the views from Hakone and the Fuji Five Lakes are superb, as covered in our one week in Japan itinerary.
Can you hike Mount Fuji outside the official season?
The mountain is not closed in the sense of being physically barred, but outside the official season the huts are shut, the mountain first aid stations are unstaffed, and the weather and snow make it a serious undertaking rather than a walk. Local authorities strongly discourage off-season ascents, and anyone attempting one is expected to be equipped and experienced for winter mountaineering.
Which Mount Fuji trail should I choose?
The Yoshida Trail is the usual answer for a first climb, because it has the most huts, the best public transport access from Tokyo, and separate up and down paths. Fujinomiya is the shortest route to the summit but steeper, and Subashiri and Gotemba are quieter and less supported.
Can anyone climb Mount Fuji?
No technical climbing skill is needed, and large numbers of ordinary walkers reach the summit each season. The difficulty comes from the sustained height gain, the thin air near 3,776 metres, and weather that changes quickly, so reasonable fitness and proper preparation matter more than experience.
