Mt. Fuji Live Weather, Trail Conditions & Safety Updates

Our guiding teams are on the mountain from early July through early September. This section is updated directly from our lead guides.

Trails officially open July 1st (Yoshida and Subashiri Routes) and July 10 (Gotemba and Fujinomiya Routes).

5th Station access roads are currently clear. Upper mountain trails are undergoing pre-season preparations.

Preparing for opening day.

A common mistake for climbers is checking the weather forecast for Tokyo or the base towns and assuming the mountain will be the same.

Mt. Fuji is an isolated volcanic peak rising 3,776 meters (12,388 feet) above sea level. It creates its own aggressive microclimates.

Always expect hot, cold, dry & wet conditions for each climb.

As a rule of thumb, you will lose roughly 6.5°C of temperature for every 1,000 meters of elevation gained. If it is a humid 30°C in Tokyo, it can easily be near 0°C (or freezing with wind chill) at the summit.

Because there are no surrounding mountain ranges to block the air currents, Mt. Fuji invites high winds. A gentle breeze at the 5th station can easily turn into violent, 20+ m/s gale-force winds at the summit, making progress dangerous.

Clear morning skies can shift into thick cloud cover, dense fog, and/ or torrential alpine rain rapidly.

We maintain absolute operational transparency. A scheduled climb will be officially canceled or halted if any of the following parameters are met:

Immediate cancellation if the Japan Meteorological Agency issues official typhoon warnings or severe weather alerts for our operational region.

If regional authorities close the mountain access roads due to rockslides, heavy erosion, or extreme weather conditions, preventing transit to the 5th Stations.

If sudden, unexpected mountain developments cause; high winds make walking unstable, creating an immediate risk of falls during either the ascent or descent, etc.

Safety at Mt. Fuji Guides is heavily systematized through internal reporting.

We do not leave safety up to chance:

Cancellation if the Japan Meteorological Agency issues official typhoon warnings or severe weather alerts affecting the safety of the trip.

Prior to every single departure, our guiding team must complete and submit an AM Form. This includes a thorough analysis of current weather models, climber health/allergy reviews, and a localized safety plan tailored to the day's specific mountain conditions.

Within 12 hours of completing a climb, our guides are required to submit a comprehensive Post-Trip Report. This protocol ensures documentation of group tracking, gear performance, safety analysis, and immediate reporting of any field incidents.

By applying these pre- and post-tour reporting standards, we maintain a continuously updated database of mountain logistics, ensuring that we are the most informed and responsive operators that we can be.
