National Park Mountain Running Nikko is one of Japan's premier trail running events, offering a rare opportunity to race through the breathtaking landscapes and cultural heritage of Nikkō National Park. Held each autumn in Nikkō City, Tochigi Prefecture, the event combines challenging mountain terrain with UNESCO World Heritage landmarks, making it one of the country's most distinctive trail races. Participants traverse centuries-old pilgrimage routes, forest singletrack, highland trails, and panoramic ridgelines while experiencing the remarkable blend of natural beauty and spiritual history that has made Nikkō one of Japan's most celebrated destinations. The race is designed to showcase the region's unique environment while promoting responsible outdoor recreation within one of Japan's oldest national parks.
The event features multiple distances to accommodate a wide range of runners. The flagship Ultra Course (75 km) is an endurance challenge that climbs through the mountains surrounding Nikkō, while the Middle Course (35 km) and Short Course (15 km) provide shorter but equally scenic experiences. The race begins in the heart of Nikkō's historic temple district, passing the Shrines and Temples of Nikkō, a UNESCO World Heritage Site, before ascending into the Kirifuri Highlands, where runners encounter expansive grasslands, mountain forests, waterfalls, and spectacular viewpoints across the national park. The varied terrain includes paved roads, technical mountain trails, forest paths, and alpine sections that reward participants with unforgettable scenery throughout the day.
