Off-Season Climbs

Climbing Mt. Fuji in the off-season can be an extremely peaceful experience as the trails and most of the mountain huts are completely deserted.

Off-Season Climbs Dates

Slight Off-Season Climbs: (June, September and October)
Climbing in the months just before and just after the climbing season I.e. (June, September and October) is actually preferred by some hikers who like to avoid the crowds. The weather varies depending on the month, but for the most part the weather is not so different from the weather during the climbing season. There are some mountain huts that remain open, however all other toilets and safety facilities are shut. (As all signposts are removed in the off-season recommend climbing with a mountain guide)

Deep off-Season Climbs: (April, May and November)
During these months, the weather can be very unforgiving; and as there are no mountain huts open during this time your only option is a 1-day climb. If you climb in April or May you will defiantly need crampons. (Of these months, May is your best weather choice for doing a 1-day climb) As the mountain is typically covered in snow climbing with a mountain guide is a must and you should never climb alone.)

Winter off-Season Climbs: (December, January, February, March)
Due to the extreme climate, (horrendous winds, subzero temperatures) this is the most dangerous time to climb Mt. Fuji and accordingly produces the most fatalities of all the seasons. The icy slopes, horrendous winds and subzero temperatures enhances the climb dangers by ten folds. I would unequivocally avoid climbing Mt. Fuji during the winter months.

Off Season Climb Advice

Despite the risks and warnings, some people will undoubtedly choose to climb Mt. Fuji in the winter off-season anyway. For those people who ignore all the warnings and accept all personal responsibility for their own safety, here are some off-season climbing tips:
 
1. Use the Fujinomiya Route: This is the most popular off-season route, as it is the shortest route to the summit. There is only one-way up and one-way down so it is less likely to get lost compared to the other routes and as this route is preferred by most in the off-season you will likely not be alone, especially if you climb on a sunny weekend.
 
2. Use the tractor trails: Normally, using the tractor/bulldozer trails is strictly forbidden during climbing season, however once all the mountain huts are closed, these trails are unoccupied and may be your best option for a quick descent.
 
3. Employ a professional guide: and bring the following equipment; crampons (twelve nails and well-shaped), an alpine ice axe, climbing rope, a pair of ski stocks, food, water, thermos and hot drinks (coffee, soup, etc.), heavy weather wear, a warm cap, snow goggles, and a flashlight.
 
4. Register with the local police before climbing in the deep off-season: Both Yamanashi and Shizuoka mountain safety authorities do not recommend you climb during the off-season. However if you do, they ask that you submit a climbing plan one week before you climb. The climbing plan lists the route, schedule equipment, group members and emergency contact details. The climbing plan form can be obtained from the official climbing Fujisan website: On-Line Guidelines and faxed to the location depending on your expected climbing route.
