I want to climb Fuji in winter
by Chris White

Snow capped Mt Fuji is one of the world's most iconic sights. What the photographs don't convey is the severity of climbing Fuji "out of season." Obligatory disclaimer: climbers, experienced alpinists and gumbies alike, die every year on Fuji. Risk of death or serious injury is quite possible. None of the below is a recommendation to attempt the mountain out of season. You climb entirely at your own risk and should realize the inherently dangerous nature of the undertaking.

What is "out of season"?

The official season starts in early July and ends in early September. After that, the mountain is "closed", although it's worth noting that the huts will sometimes open a little in advance and often stay open for a week or so afterwards. The only hut on the mountain that offers (albeit sporadic - mainly weekends during winter) year round opening is Sato-goya at the 5th stage. If you climb out of season, then assume that there is no support & that you're on your own to the top.

Can I climb when the mountain is "closed"?
Yes, but the rise in out of season fatalities has raised the occasional police presence on the mountain during winter. They won't stop you climbing (apparently) but can and will inspect your gear, and will urge you to descend if they think you are under prepared. They're generally good guys, if somewhat officious, so try not to give them a hard time for doing their job.

Is the road open?
Depends on snowfall. The road to the 5th stage is not infrequently closed during winter, which means you'll be climbing from the 1st stage at Uma-gaeshi. If the path is relatively clear, then it's a couple of hours from there to the 5th stage. It's not unknown, though, for there to be several feet of snow after a decent storm, which will require snow shoes and considerable stamina to break through.

What are the risks?
  • Fuji is very, very cold in winter. People come from all over Asia to train on Fuji for Himalayan ascents. Temperatures of -40C with wind chill above the 8th stage are the norm.
  • It can be extremely windy. Gusts of 100mile/hr and above are not uncommon, enough you knock you over and send you skidding down the mountain (see below). Wind is probably the most key factor in summitting - if there's a plume on the top then you're probably best off turning back.
  • It can be extremely icy. That white capped cone is, after a couple of days of cold wind, a scoured ice slope. Against this, the mountain is neither steep nor technical enough to require ice tools or roped belays. The result is that you'll be spending many hours at reasonable altitude, fatigued, and at risk of a slip. If you do slip, you'll have at most one chance to self arrest, and if you miss that then you're probably taking a highly injurious or fatal one-way trip down the mountain. People die this way every single year on Fuji in winter. Don't be among them.
  • Coming down is harder than going up. You'll have done a big day going up and now you're facing at least a 2000m descent on snow and ice that has been degraded by the daytime sun in all likelihood.

Should I climb Fuji in winter?
If you enjoy big, technical alpine routes in winter, then there are many better routes in Japan. But it remains an icon in the Japanese mountain pantheon, and is a tick many feel they have to acquire.

If you're fit, have adept winter mountaineering experience, and are sensible with regards to the very changeable conditions on the mountain, then Fuji in winter represents an interesting and memorable challenge.
