High point 2,870m ／ Total ascent approx. 1,408m ／ 1,408m of climbing from Nakabusa Onsen trailhead (1,462m)
Hut (tap for details) Trailhead Point passed Elevation not confirmed
The horizontal axis is the order of the route, not time: we have not confirmed this route's leg times against an official source. The ridge line simply joins the recorded points, so it does not show the real shape of the terrain. Total ascent is an approximation summed between those points. Chogatake Hutte have no confirmed elevation, so they are placed provisionally between the points either side.
Stop by stop
Section times are estimates from the path length, climb and descent (a formula fitted to Nagano Prefecture's grading table; typically within about 10%).
