Kiroro Snow World 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 west.
Where this vertical sits among the mountains on JapowDB
660 m, more than 16 of the 34 mountains on JapowDB.
The mountain
朝里岳・長峰岳 (Asari-dake and Nagamine-dake)
- Above it
- 余市岳 (Yoichi-dake) 1,488 m
- Landform
- You ski the sides of two volcanoes here. Asari-dake is a basalt cone, and its summit is so flat that skiers call it the airfield. The lifts stop at 1,180 m, about a hundred short of that summit, and much further below Yoichi-dake.
- Rock
- One rock from top to bottom: andesite and basaltic andesite lava with the debris it threw out, Miocene to Pliocene. Sampled at the top of the lifts and again halfway down, it does not change, and that is the plainest reason every slope here leans the same way.

That ground is outside the ski area. It is not patrolled.
Measured
01
Which way it faces
Faces west.
Most of the mapped runs fall away toward the west.
02
How steep it gets
That steep ground sits high on the mountain.
Its steepest tenth is steeper than 10 of the 34 mountains here that carry pitch data.
16.9° the steepest tenth of runs
03
How varied it is
Its runs range from 2.9° to 17.9°.
Half of them are gentler than 9.9°. Each mark is one run.
That spread is wider than 14 of the 34 mountains here that carry pitch data.
04
What grows on it
Mostly deciduous: broadleaf woods and larch. They stand bare through the winter, so you can see a long way into them.
