With over 100,000 trekkers each year, this sacred mountain—which, along with Mount Tate and Mount Haku, rounds out Japan’s “Three Holy Mountains”—has become a truly global pilgrimage. The steep climb follows four trails, each lined with concession stands and beds, and is a full-day hike. The picturesque mountain, which was first climbed by a monk in 663, was closed to foreigners and women for hundreds of years. Nowadays, though, anyone can hop the train from nearby Tokyo and catch the breathtaking sunrise from Fuji’s peak.
