Togakushi 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 west, north-west and south-west.
Where this vertical sits among the mountains on JapowDB
528 m, more than 17 of the 49 mountains on JapowDB.
The mountain
瑪瑙山・怪無山 (Meno-yama and Kenashi-yama)
- Above it
- 飯縄山 (Iizuna-yama) 1,917 m
- Landform
- A volcano. Meno-yama is one of the peaks of the Iizuna volcano, the southernmost of the Myoko volcanic group, a stratovolcano with lava domes that was active from about 340,000 to 60,000 years ago. Iizuna's own summit stands about 1.4 km to the southeast, across a col roughly 100 m deep. Kenashi-yama, the lower peak to the west, stands on the same lava.
- Rock
- Iizuna's own lava. From the top of Meno-yama down past 1,340 m, on both peaks, the runs sit on andesite and basaltic andesite lava and pyroclastic rock from the middle Pleistocene, one volcanic body across every face the lifts reach. Only at the bottom, near 1,220 m, does that give way to young fan and talus deposits, the material the mountain has shed onto its foot.

That ground is outside the ski area. It is not patrolled.
Measured
01
Which way it faces
Several faces: west, north-west 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 31.1°.
Its steepest tenth is steeper than 23 of the 49 mountains here that carry pitch data.
17.9° the steepest tenth of runs
03
How varied it is
Its runs range from 1.8° to 24.6°.
Half of them are gentler than 13.2°. Each mark is one run.
That spread is wider than 44 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.
