Overview
The Chōkai Blue Line is a 34.9km mountain scenic route connecting Fuipura, Yuzawa-machi, Akumi-gun in Yamagata Prefecture to Kotaki, Shōgata-machi, in Nikaho City, Akita Prefecture. It climbs dramatically from sea level to 1,100 meters, offering stunning views of the majestic Mount Chōkai, the expansive Sea of Japan, and the Shonai Plain.
The Yamagata side winds through beech forests, while the Akita side meanders through vast grasslands at the foot of Mount Chōkai, providing diverse and ever-changing scenery. The beech forest on the Yamagata side is a particular highlight, offering a refreshing drive through a mystical, primeval forest.
Near the summit, you'll find the Ōhira Sansō, a lodging facility where you can enjoy a day trip bath and meals. It also serves as a base for climbing Mount Chōkai, making it a perfect combination to drive the Chōkai Blue Line and then embark on a climb.
The Chōkai Blue Line is also captivating for its seasonal beauty—spring greenery, summer foliage, and autumn leaves. It's a beloved drive offering beautiful nature throughout the year.
