Geto Kogen: the tree-run zones
11 zones, 46.6 hectares, drawn by the resort itself — with 29 marked hazards and 62 numbered rescue points.
Off-piste skiing in Japan is forbidden by default, so a resort that permits it draws the ground where it is permitted and names every piece. Geto Kogen publishes that as a map in real coordinates rather than as a picture, which is why this page can show you the shapes instead of describing them.
The zones
English spellings appear where the Japanese name is an English word written in katakana — シューター is Shooter. Areas are measured from the resort's own outlines.
| Zone | Area | Rescue markers |
|---|---|---|
| Beach ビーチ | 10.1 ha | 11 |
| Shooter シューター | 9.5 ha | 10 |
| Summit サミット | 8.7 ha | 13 |
| Stream ストリーム | 4.4 ha | 9 |
| Extreme エクストリーム | 4.1 ha | 4 |
| Cascade カスケード | 3.4 ha | 5 |
| Rabbit ラビット | 2.2 ha | 3 |
| Alta アルタ | 1.6 ha | 2 |
| Garden ガーデン | 1.3 ha | 3 |
| Heart ハート | 0.8 ha | 2 |
| Juukidou | 0.5 ha | — |
What the numbered dots are for
The 62 small dots are numbered signs on the ground, each named for the zone it stands in. They exist so somebody in trouble can say which one they are beside and have patrol know where that is: the resort calls the map a 位置確認ツール, a position-checking tool, and that is the reason these coordinates are public at all.
The rules, in the resort's own words
Quoted rather than summarised. 「着用を義務」 (compulsory) and 「着用を推奨」 (recommended) differ by one word, and only the operator's own page is current.

Where this came from
The geometry is the resort's own published map, titled 夏油ツリーラン, projected about its own centre so that one unit of the drawing is one metre. Nothing is traced and nothing is inferred: every outline, hazard and marker sits where the operator put it. OpenStreetMap holds no gladed terrain here at all, which is why this resort does not appear on the site's other tree page.
