Kashimayari Snow 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 south and south-west.
Where this vertical sits among the mountains on JapowDB
490 m, more than 7 of the 40 mountains on JapowDB.
The mountain
- Landform
- Not a volcano. This is a foothill rising straight off the west shore of Lake Nakatsuna, one of the three Nishina lakes, which formed along the Itoigawa-Shizuoka Tectonic Line. The Kamishiro Fault, the northernmost strand of that line, runs north-south through all three lakes and pushes the ground on its east side up. The volcanic rock in the hill is around 50 to 65 million years old, far older than any volcano that is active today.
- Rock
- Its roughly 490 m of vertical crosses four kinds of ground. Much of the top of the lifts, from about 1,200 m up, is Early Jurassic marine mudstone, the oldest rock the runs cross. Most of the skiing below that is dacite and rhyolite laid down by huge pyroclastic flows 66 to 48 million years ago. Around 900 m the runs cross granite of the same age, and the base sits on young fan and talus deposits.

That ground is outside the ski area. It is not patrolled.
Measured
01
Which way it faces
Several faces: south and south-west.
The mapped runs fall away down more than one side of the hill.
02
How steep it gets
The steepest quarter of the runs faces north, a different way from the mountain overall.
Its steepest pitch measures 34.7°.
Its steepest tenth is steeper than 12 of the 40 mountains here that carry pitch data.
16.4° the steepest tenth of runs
03
How varied it is
Its runs range from 8.0° to 22.7°.
Half of them are gentler than 10.9°. Each mark is one run.
That spread is wider than 17 of the 40 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.
