Rusutsu Resort 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 north-east.
Where this vertical sits among the mountains on JapowDB
594 m, more than 12 of the 34 mountains on JapowDB.
The mountain
橇負山 (Sorioi-yama) 994 m
- Landform
- A low volcanic hill, and the lifts run right to the top of it. That cone on the horizon is Yotei, and it is a different mountain entirely, standing across the valley. Because it is over there, you can see all of it at once.
- Rock
- Andesite and basaltic andesite lava with its own debris, early Quaternary, and it does not change between the top of the lifts and the bottom. The whole hill is one volcanic pile, put down gently.

Measured
01
Which way it faces
Faces north-east.
Most of the mapped runs fall away toward the north-east.
02
How steep it gets
The steepest quarter of the runs faces east, a different way from the mountain overall.
Its steepest tenth is steeper than 20 of the 34 mountains here that carry pitch data.
19.1° the steepest tenth of runs
03
How varied it is
Its runs range from 3.0° to 27.6°.
Half of them are gentler than 13.2°. Each mark is one run.
That spread is wider than 32 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.
