A scenic road in Nikko, famous for its breathtaking autumn foliage views.
Connecting central Nikko to Lake Chuzenji, this 15.8 km scenic road is a renowned tourist route. It consists of two separate roads: the "First Irohazaka" for descending and the "Second Irohazaka" for ascending. The road features 48 hairpin turns, named after the 48 characters of the ancient Japanese syllabary "Iroha." The origins of Irohazaka trace back to the mountain worship of Mt. Nantai, dating to the Nara period. Due to its sacred nature, the Okunikko area, which begins at Irohazaka, was considered holy, and women were prohibited from entering until the Meiji era. The area was developed and opened in the Showa era.
Both sides of the road are lined with Nikko’s lush natural beauty, with autumn foliage offering a spectacular display. With a 440-meter elevation difference, the best time to view the fall colors varies depending on altitude, allowing for an extended period of vibrant scenery. A highlight is Akechidaira, located midway along the Second Irohazaka. From here, you can take a ropeway to the Akechidaira Observation Deck, where you can enjoy a panoramic view of Lake Chuzenji, Mt. Nantai, and Kegon Falls, all beautifully framed in autumn colors.
While the journey typically takes about 20 minutes, during the peak autumn season, the road can become congested with visitors seeking the scenic views, and it may take 2–3 hours. To avoid traffic, it’s recommended to visit early in the morning or plan for a relaxed schedule.

In Nikko, you’re sure to pass through the famous Irohazaka Winding Road! The most distinctive thing about this mountain road is its series of curves. As it winds its way up the mountain, driving here really feels like a “mountain road adventure.”
As you head farther up the mountain, the scenery outside the window keeps changing, from forests to valleys, with the view becoming more and more expansive. Especially during the fall foliage season, the entire mountain turns red and yellow, and driving through scenery like this is truly beautiful.
Irohazaka is also an important road for reaching Nikko attractions such as Lake Chuzenji and Kegon Falls, so it’s usually included in the same itinerary. Although there are many curves along the way, they also make enjoying the mountain scenery more fun.
Passing through Irohazaka this time, I felt that it’s not just a “transportation route,” but part of the Nikko travel experience itself. If you come to Nikko by car or bus, seeing these continuous curves and the mountain forest scenery will help you appreciate Nikko’s natural beauty even more!
The Irohazaka mountain road is full of twists and turns, but the bus driver was incredibly skilled. I didn’t feel scared or carsick at all going up or down the mountain.
Watching the mountains covered in red autumn leaves through the window was amazing, and every turn brought a different view.
Even better, we didn’t run into the traffic jams we’d heard about. Being able to enjoy this fall foliage trip without having to drive ourselves made it absolutely perfect.
