The Yamanami Highway is a scenic 58 km mountain road that connects Beppu City in Ōita Prefecture with Aso City in Kumamoto Prefecture. Officially known as Prefectural Route 11 (Beppu–Ichinomiya Line), it is famous among riders for its breathtaking views of the Kuju Mountains and Mount Aso. The route reaches elevations over 1,000 meters, making it one of Kyushu’s premier highland drives.
Highlights and Attractions
Along the way, you’ll enjoy expansive views of the Kuju Highlands, Iida Highlands, and the Aso outer rim mountains. The scenery changes with the seasons—lush greenery in spring, cool breezes in summer, vivid autumn foliage, and snow-covered landscapes in winter. On clear days, panoramic views stretch for miles.
Road Conditions and Safety
The entire route is well-paved and maintained, with gentle curves that are easy to ride even for beginners. Since it passes through high elevations, weather conditions can change quickly. In winter, icy patches are possible, and snow tires or chains may be required. Traffic is light, and there are few traffic lights, making it ideal for a relaxed and scenic ride.
