Despite the numbers, and the infrastructure that has been built to serve them, the mountain is not without its challenges. Altitude is one of the most significant; there is little chance to acclimatize on the hike and, approaching 4,000 meters in height, the mountain is easily tall enough to induce altitude sickness in even the fittest of climbers. Another is exposure: Above the treeline there is very little shelter, Fuji is so prominent that nothing blocks incoming weather, and conditions can change very quickly.
However, to summit Mount Fuji is a great challenge, one that should be relished. The view of Japan from the top is unparalleled, especially when sunrise is thrown into the mix. With this guide, you should have an idea of what to expect from the mountain, and what is needed to make a successful summit.
When to climb
The climbing window for Mount Fuji begins July 1 each year, when the Yoshida Trail opens, and lasts till Sept. 10. The other three trails open July 10. During this time, all trails are well serviced by public transport, mountain huts are open and emergency services and first aid are more readily available. Bear in mind that weekends are much busier than weekdays, with Saturdays the most crowded.
It is possible to do an off-season climb of Mount Fuji — and even ski the mountain during the snowy months — but that requires specialist equipment and knowledge that is beyond the scope of this guide. In the off-season, huts are closed and there is no available public transport. Multiple fatalities occur each year among people trying to summit the mountain in the off-season.
