What this is
Shio-no-Michi (The Salt Road) is an ultra-distance trail race following the historic trade routes that once carried salt from the Sea of Japan coast through the mountains of Niigata and Nagano prefectures. These ancient pathways were vital arteries of pre-industrial Japan, connecting coastal salt producers with inland mountain communities for centuries. The race offers distances ranging from 50km to over 100km, with technical mountain terrain and significant elevation changes throughout. It stands as both a serious athletic challenge and a living tribute to Japan's pre-modern trade heritage, making it one of the more culturally resonant ultra-running events in the country.
Who should go
This event is designed for serious ultra-runners and experienced trail running enthusiasts who are comfortable with demanding mountain conditions and multi-hour efforts in remote terrain. The atmosphere blends competitive spirit with a genuine appreciation for historical landscapes and mountain culture, attracting participants who value the journey as much as the finish line. International runners will find well-organized aid stations and clear course marking, though some basic Japanese language ability is helpful for interactions with local volunteers and staff. Come fully prepared with appropriate mountain running gear, navigation skills, and a training base suited to your chosen distance and elevation profile.
Good to know
Race registration for Japanese trail ultras typically opens several months in advance via platforms such as RUNNET (runnet.jp) or the official race website — foreign credit cards are not always accepted on RUNNET, so have a Japanese payment method or use a proxy registration service if needed. The course runs point-to-point from Matsumoto to Itoigawa, so plan your accommodation and transport at both ends in advance, as the two towns are in different prefectures and require separate logistics. Aid stations are reported to be well-organized, but self-sufficiency is expected on the mountain sections — carry sufficient nutrition and water between checkpoints. June in the Japanese Alps can bring unpredictable weather including rain and low cloud, so waterproof layers and a headlamp are essential regardless of your start time. Post-race, Itoigawa is a small coastal city with limited late-night food options, so arrange your recovery meal and accommodation well ahead.
