Overview

Chokai Blue Line — Sea-to-Sky Volcano Skyline.

The Chokai Blue Line is a 34.9km sea-to-sky mountain road that climbs from the Sea of Japan coast to 1,100m on the flank of Mt Chokai, the great 2,236m volcano known as Dewa Fuji. Straddling the Akita-Yamagata border, it rises from Basho's tidal islets at Kisakata through beech forest to a high observation deck where the Oga Peninsula, Awashima Island and the whole Shonai plain spread below. One of Tohoku's great touring roads.
