Calm conditions persist on Fuji with some conflicting reports about what the future of weather will be on the mountain. We've got reports calling for plenty of rain but also another report not calling for rain at all. So it appears to be a mixed bag and no one quite knows what you'll be in for on a Fuji climb in the next 2 days.
That aside, you can at least count on low winds of about 10-20kph on the summit and moderate temperatures of 4-8 degrees C.
Climbers in these conditions should be prepared for rain with proper rain gear and hiking boots.
This time of year is especially crowded on Mt. Fuji so climbers should be prepared for lots of crowds on the summit!

With Typhoon #13 out of the way, we're back to business as usual on Mt. Fuji. Current conditions are relatively calm with light winds and moderate temperatures. The weather is a little bit of everything right now alternating between clear blue skies, clouds and some rain expected.
Calm conditions like this tend to promote thunder clouds on Mt. Fuji so climbers should keep an eye out for any thunderheads which may develop, and take shelter in a hut if there is any activity.
As of 9pm the typhoon is lingering off the east coast of Tokyo, surprisingly unable to push through the landmass to the Sea of Japan.
Over the course of the evening the typhoon will continue pushing against the coast but it scheduled to lose power in this process and start moving north as it weakens. Its weakening so fast that by 9am tomorrow the system is forecast to have lost most of its land-battering power, although it will still remain strong at sea.
As such, our forecast models are calling for harsh conditions to subside by 9am, with winds at the summit predicted to be a topical 30kph (by 9am) moving down to 15kph by the end of the day.
Of course climbers should assess real life conditions on the mountain to decide whether or not to climb.
Weather alert **TYPHOON**
While the Mountain today had relatively calm weather, Typhoon #13 is bearing down on Japan quickly with Mt. Fuji forecasted to be significantly affected.
Starting tonight and going on until at least Thursday morning (Aug 9), Mt. Fuji is forecasted to get blasted with winds exceeding 100kph with gusts on top of that. In addition, massive amounts of rain are forecasted to fall. Visibility will also be zero as the Mountain is enveloped in a cloud.
THERE SHOULD BE NO ATTEMPT TO CLIMB MT FUJI FROM THE EVENING OF AUGUST 7 TO THE MORNING OF AUGUST 9 AT LEAST. THE MOUNTAIN IS EXTREMELY HAZARDOUS IN A TYPHOON. CLIMBERS RISK BEING BLOWN OFF THE MOUNTAIN, BEING BLASTED BY SAND AND DIRT, BEING CAUGHT IN MUD/ROCK SLIDES AND GETTING DISORIENTED AND LOST.

Generally fair conditions persist on Mt. Fuji with clear skies at the beginning of today moving to rain showers, fog and clouds in the afternoon and evening.
Come tomorrow, you can expect a little bit of everything. The day is expected to start off with rain, then move to fog and then become clearer later in the day.
It's anyone's guess what the sunrise will look like in these conditions as it could be anywhere from perfect to whiteout.
Safety wise, the temperatures and winds will remain moderate but given that there's rain in the forecast, if you don't have proper rain gear you will get very cold even with 6-8 degrees C temperatures and moderate winds.
Be safe out there and I wish you a happy sunrise!

Beautiful weather persists on Mt. Fuji with moderate winds and clear skies. Clear skies are expected until noon tomorrow when there will be clouds developing with the afternoon warmth, but those are expected to burn off towards the end of the day.
Summit temperatures are between 4-8 degrees C with moderate wind chill subtracting 2-4 degrees from the official temperature.
All in all, conditions are great for a good climb of Mt. Fuji and the likelihood of a textbook-perfect sunrise is high.
Of course, favorable conditions like this always increase the likelihood of a thunder clouds so climbers should keep an eye out for the development of thunderheads and take shelter if lightning is spotted.
Sunny weather means the chances for getting sunburned are very high--climbers should apply sunblock every few hours to keep from getting toasted.
Have fun out there tonight and enjoy the great conditions!

Winds on Mt. Fuji continue to be moderate but the chance of rain at lower elevations is quite high throughout today. Higher elevations are less likely to experience rain but depending on the movement of wind and clouds, climbers today should have their rain gear at the ready.
Highs at the summit are expected to be between 4-6 degrees C without windchill. Winds should not be in excess of 10-20kph. All in all, climbers today and tomorrow should expect a little bit of everything.
General conditions are favorable for the development of thunder heads so climbers should be on the lookout for ominous looking clouds for a risk of lightning.
The sunrise could be a mixed bag depending on the specific conditions at summit. Here's to hoping for a good break in the clouds for a great sunrise!

With the passing of typhoon #12, most of the weather now is clear and relatively calm on Mt. Fuji. While clear skies are expected above 3200m, cloud cover is expected below that, providing good sun-coverage for climbers.
Winds continue to die down throughout the day with summit winds expected to hit a mellow 15kph toward the end of the day.
The upcoming week is expected to continue to be pleasant weather with moderate winds and light rain expected here and there.
Influenced by typhoon #12, the weather on Mt. Fuji has been severely rainy with high winds of about 100kph on the summit. Visibility is also low.
Climbers should not attempt to summit or climb the mountain today. Further, roads and trains to/from Mt. Fuji tend to close down in a typhoon event so its best to skip a Fuji visit for the moment.
Looking to the next few days, the weather will open up Sunday morning and while Sunday will still be windy at the summit, it should begin dying down by noon and clearing up more in the following days.
Monday is forecast to be back to regular good climbing weather with low winds and sunny skies.
Weather today on Fuji has started off sunny with very little wind, but the conditions will gradually become more turbulent as the day goes on with rain showers, clouds and higher winds expected in the PM. Temperatures on the summit are expected to be around 4-6 degrees C with higher winds making the "feels like" temperature 2-5 degrees colder.
IMPORTANT WEATHER UPDATE
A typhoon is moving through on Saturday so climbers should not attempt a climb on this date. Extreme winds, severe rains and low visibility are expected on Saturday.
