Terrain
Colours show terrain angle (30° yellow, 35° orange, 40° red, 45°+ purple). Most avalanches start on 30–45° slopes, but no colour does not mean safe. Overlay your own GPX/KML to see distance and slope (the file is read on your device only, never uploaded).
Map & elevation: GSI Japan (slope computed by Japow Now! from the 10 m elevation tiles)
