This area offers a field where you can enjoy a variety of activities such as trail running, mountain biking (MTB), and backcountry (BC) skiing, each season bringing its own beautiful scenery.
Okushinano also has numerous hot springs. After the race, please fully enjoy Japan's traditional hot spring culture. We have created a 100km course with the desire for you to fully experience the charming nature of Okushinano. We are confident you will be satisfied."

3 round trip courses of mountain and village

• A countryside round trip, running through orchards and pastoral landscapes

"The Okushinano 100" encompasses these three rounds. Along the way, there are historic trails that connect villages, beech forests that have withstood the weight of snow, trails along streams fed by melting snow, and landscapes of mountain hamlets filled with nostalgia and tranquility. It's a 100km journey packed with the natural beauty and charm of Okushinano, so please enjoy it to the fullest.

Features of the race

* The Okushinano Ultimate Trail Journey

You will encounter paths filled with natural beauty, such as primeval beech forests that are 300 years old, the beautiful rural landscapes of Kijimadaira, historic trails, and paths leading to orchards.
