Hotaka Rock Climbing offers multi-pitch alpine climbing on the granite faces of the Hotaka range in the Northern Japan Alps, accessed on foot from Kamikochi via the Karasawa Cirque near Matsumoto City, Nagano. This is alpine mountaineering-style climbing rather than sport cragging, and it is best suited to climbers with prior rock climbing or mountaineering experience; complete beginners should look for shorter guided crag routes elsewhere. Climbers reach the base of the routes via a two-to-three-hour uphill approach from the Kamikochi valley floor, then continue over one to two days depending on the route chosen, often overnighting at Karasawa or Hotakadake mountain huts. Guided ascents through EVERGREEN Outdoor Center Hakuba include a harness and helmet, with technical climbing shoes either brought by the climber or rented at the base; a sleeping bag is needed for hut nights. EVERGREEN is an established Hakuba-based outdoor operator staffed by certified alpine guides who lead route selection, set anchors on technical sections, and monitor conditions throughout the ascent. Because the terrain is remote and weather in the Northern Alps can shift rapidly, guides give a safety briefing before departure covering communication protocols, turnaround points, and hut-based shelter in case conditions deteriorate; helicopter evacuation is the fallback for serious injuries given the terrain's remoteness. The climbing season runs from July to September, with August generally offering the driest rock and most stable weather; snow and ice can still linger on north-facing sections early in the season.
