Shiga Kogen Kumanoyu Mountain
The landform the resort sits on: the shape of the hill beyond the pistes, how steep it gets, and where it stands among the mountains on JapowDB.
Broadly one hillside, leaning to the north-north-east.
Where this vertical sits among the mountains on JapowDB
270 m, more than 3 of the 49 mountains on JapowDB.
The mountain
- Above it
- 横手山 (Yokote-yama) 2,307 m
- Landform
- Not a volcano of its own. The runs lie on the north side of a ridge of old volcanic rock. Two much younger volcanic peaks rise on either side of it: Kasagatake (2,075.8 m) to the west and Yokote-yama (2,307 m) to the east. Kasagatake is the sharp, hat-shaped summit you see beside the ski area.
- Rock
- Every run sampled, from the top of the lifts at 1,952 m down to the base at 1,680 m, sits on one formation: andesite and basaltic andesite lava and pyroclastic rock from the early-to-middle Miocene, roughly 15 to 20 million years old. That is far older than the volcanic peaks either side. The summit of Yokote-yama is early Pleistocene and Kasagatake is late Pleistocene, both under about 2.6 million years. The ski area is on the old basement those younger cones were built beside.

That ground is outside the ski area. It is not patrolled.
Measured
01
Which way it faces
Faces north.
Most of the mapped runs fall away toward the north.
02
How steep it gets
That steep ground sits high on the mountain.
Its steepest pitch measures 28.7°.
Its steepest tenth is steeper than 34 of the 49 mountains here that carry pitch data.
20.1° the steepest tenth of runs
03
How varied it is
Its runs range from 8.1° to 20.4°.
Half of them are gentler than 14.5°. Each mark is one run.
That spread is wider than 10 of the 48 mountains here that carry pitch data.
04
What grows on it
This mountain has both, in separate patches. The deciduous stands drop their leaves and open up for the winter; the conifer stands stay closed.
