Niseko United 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.
This mountain faces several ways at once, mostly east.
Where this vertical sits among the mountains on JapowDB
933 m, more than 44 of the 50 mountains on JapowDB.
The mountain
ニセコアンヌプリ (Niseko Annupuri)
- Landform
- A stratovolcano, and the main peak of the Niseko range. It threw out andesite lava over and over between roughly 700,000 and 250,000 years ago, then went quiet. The four ski areas sit on four sides of the one cone, and the lifts stop about 120 m under its 1,308.2 m summit.
- Rock
- Andesite and basaltic andesite lava with its own debris, middle Pleistocene, and the same top to bottom. The cone is built out of what it erupted.

Measured
01
Which way it faces
Faces east.
Most of the mapped runs fall away toward the east.
02
How steep it gets
That steep ground sits high on the mountain.
Its steepest tenth is steeper than 29 of the 50 mountains here that carry pitch data.
18.7° the steepest tenth of runs
03
How varied it is
Its runs range from 2.7° to 21.9°.
Half of them are gentler than 13.1°. Each mark is one run.
That spread is wider than 37 of the 49 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.
