Irohazaka Climb

Irohazaka is one of Japan’s most famous winding roads, located in Nikko, Tochigi Prefecture. Known for its steep curves and stunning natural scenery, it consists of two separate roads: the “First Irohazaka” for ascending and the “Second Irohazaka” for descending. Each road features 48 curves, named after the old Japanese syllabary “Iroha,” which is how the road got its name.

This route is especially popular during the autumn season when vibrant fall foliage transforms the landscape into a breathtaking sight. However, cycling here can be challenging due to the elevation gain on the way up and the high speeds possible on the way down, requiring careful braking techniques.

The Route
