Japan observation deck
Yokoyama Viewpoint
You can see 213 km from here, looking north-east.
Calculating the panorama…
Drag to turn around. The relief is drawn 2.2 times taller so the ridges can be read; far ridges are paler, as in the real air.
The view
Up to 213 km away.
Calculated on the relief one degree at a time, up to 250 km, with the curvature of the Earth and the refraction of the air: what stands above the horizon from here.
Our own rating, from the relief and the climate only: open horizon (35 points), how far you see (25), sea and named peaks in view (20) and clear months (20).

The 71 peaks you can name from here
From west to east as you turn around: height, distance and direction. Each one links to its guide on Peakyas, our mountain atlas.
From the relief only: buildings, trees and haze are not in the model. On a hazy day you see much less; 250 km is the limit of our calculation.
The sun
The best sunsets are in April, in August and from November to December.
