Dynaland 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 east-south-east.
That steep ground sits high on the mountain.
Where this vertical sits among the mountains on JapowDB
447 m, more than 8 of the 49 mountains on JapowDB.
The mountain
大日ヶ岳 (Dainichi-ga-take)
- Landform
- The east flank of a volcano. The national geological survey lists Dainichi-ga-take as a composite volcano of andesite and dacite, active about 1.1 million to 900,000 years ago, with no eruption on record since, and the Meteorological Agency does not list it as active. It has been worn down ever since. The summit is 1,708.9 m, about 1.7 km west-northwest of the top of the runs. The lifts stop at 1,427 m, roughly 280 m below it, and the ground climbs from there to the summit without ever dipping. Takasu Snow Park sits on the same flank of the same mountain.
- Rock
- One rock from the top of the runs to the bottom: andesite and basaltic andesite, as lava and as pyroclastic rock, laid down in the Early Pleistocene by the volcano itself. Sampled at 1,427 m, 1,150 m and 984 m, it does not change. All 443 m of lift-served vertical is on the volcano's own flank. The rock stays the same while the runs steepen higher up, so the steeper upper ground comes from the shape of the cone, which rises more sharply toward the summit.

That ground is outside the ski area. It is not patrolled.
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.
The steepest quarter of the runs faces south, a different way from the mountain overall.
Its steepest pitch measures 32.8°.
Its steepest tenth is steeper than 44 of the 49 mountains here that carry pitch data.
22.8° the steepest tenth of runs
03
How varied it is
Its runs range from 8.2° to 27.0°.
Half of them are gentler than 13.5°. Each mark is one run.
That spread is wider than 34 of the 48 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.
