SnowWind · Hokkaido snow planning

Understand the mountain. See your position and direction in context. Bring in a human when you need one.

SnowWind connects Hokkaido-specific 3D terrain with pre-trip planning, field orientation and a structured handoff to a guide. The map supports judgment; it never guarantees safety.

Backcountry

Choose a mountain, read the terrain, build the plan.

Move through Hokkaido areas with 3D terrain, slope angles, routes and daily information in one planning flow. The map is a planning aid, not a safety guarantee.

01Choose an area

Start with a published Hokkaido area.

Each area leads to its 3D terrain, recorded routes and sources. This is separate from resort mapping.

02Slope & avalanche

Read slope and route on the same terrain.

A slope-angle layer derived from the DEM, shading the 30–45° terrain where avalanches most often release. This map does not remove danger — it helps you find it. The final call must always be made on the ground.

03Today

Refresh the day before you commit.

Weather, snowpack, wind direction. Today's conditions and the daily snapshot, gathered in one place. The numbers are only a starting point — read them alongside the official avalanche bulletin, and keep the nerve to turn back.

SnowWind field app

Put yourself inside the mountain, not just on a line.

Take the same curated Hokkaido terrain into the field and read position, orientation, route, slope and hazard context on one 3D map. GPS records stay on your device and can be reviewed in 3D. The public Android release is in preparation.

Position in 3D terrain

Read where you are and where you are moving together with the shape of the mountain.

Consequences before commitment

Layer slope, hazards and route notes so consequential terrain is visible before you commit.

Record, review, plan again

Record the day, review it in 3D and, when useful, hand the same area or route to a guide.

Guides

Read the terms before you contact a guide.

SnowWind publishes an independent Hokkaido guide's listing only after checking their certification and liability insurance. SnowWind provides the directory, introduction, communication and, where available, payment tools; each guide independently provides the mountain service.
