About Mount Fuji

The official climbing season runs from July into early September, when the Yoshida Trail and mountain huts open and the summit is accessible without technical gear. Kawaguchiko and Hakone offer lake-and-onsen bases with views of the cone, and Chureito Pagoda frames it above Fujiyoshida. June and early July are generally wet, so summer days are best planned around the forecast rather than booked far ahead.
