Fields x Samurai Sports
This year, Fields is excited to partner with Samurai Sports for seven races, based primarily in Hokkaido, Nagano, and Hiroshima. This collaboration makes races more accessible for all trail runners, regardless of their ability to communicate in Japanese.
With Samurai Sports, the information needed to register for, compete in, and successfully complete races will be in English. The language barrier becomes one less headache, allowing participants to race and explore Japan stress-free.
By making Japan’s trail races more accessible and offering English-language support, Fields hopes to introduce and invite the international community of outdoor enthusiasts to dive into the world of trail running in Japan.
From the most competitive of trail runners to the casual outdoor enthusiast, Fields looks forward to welcoming international athletes from all corners of the world. Check out the races below and sign up for one today!
One of western Japan’s toughest trail races, the Hiroshima Osorakan Trail Race is a challenging course requiring runners to traverse the highest peaks of both Hiroshima and Shimane Prefectures. Intermediate to advanced athletes will find this race suitably difficult as they climb the equivalent of sea level to the summit of Mt. Fuji.
Unique for its looped course, runners will encounter the rousing cheer of supporters up to three times on the 67KM run. Line up with some of the nation’s hardiest trail runners and see where you stand!

Now celebrating its 12th year, Skyline Sugadaira treats runners to some of Nagano’s most spectacular views. Enjoy the stunning landscape as you traverse the Japan Alps, scramble down the ski slopes, and run above the clouds!
With routes that are more than 90% trail and well-stocked aid stations, trail lovers won’t be disappointed. Panoramic views of Nagano, Mt. Asama, and even Mt. Fuji will be a regular treat along the course. Those seeking a reprieve from the concrete jungles of the city can bask in the cool breezes of early summer in Sugadaira – experience it for yourself!
Outdoor sports abound all-year round in Hokkaido and during the warmer months, racing the Sapporo Teine Trail Race is a can’t-miss way to take in the breathtaking (green!) views of Japan’s northernmost prefecture!
Home to the 1972 Sapporo Winter Olympics, the Teine area is the epitome of the all-natural beauty renown in northern Japan. While staying true to the oft-grueling nature of trail running, the course is suitable for beginners and advanced runners alike.
Perennially ranked in the top 5 most popular trail races in the nation, the inov-8 Cup 9th Annual Utsukushigahara Trail Race is a bucketlist race for those up to the challenge!
With four distances ranging from 90KM to 14KM, it’s a race everyone can be a part of. Fancy yourself hardcore? Go on and bite the bullet with the technical 90KM course – includes 5,110m or about 16,700ft total ascent – and go toe-to-toe with Japan’s top athletes. Looking for something less daunting? The 14KM course is perfect (but still includes almost 1,000m of climbing)!
In Japanese, Utsukushigahara means “beautiful field” – and trust us, no matter which course you find yourself, the views of Nagano will be spectacularly scenic.
With over 600 runners joining us each year, Mt. Taisetsu is one of Hokkaido’s most popular trail races! Set in Japan’s biggest national park, the sheer scale of wilderness and nature encountered on the course is second to none.
Different from years prior, the Mt. Taisetsu Trail Journey now offers a 70KM course, the return of the 40KM course, and junior trail challenges at 5KM and 10KM. In the future, there will be a 100KM ultra trail every four years; the next one is scheduled in 2022 to celebrate the tenth edition of the Mt. Taisetsu Trail Journey.
None of these courses will be easy; however, the satisfaction you will feel when you cross the finish will be unforgettable. Don’t forget to spend some time feasting on Hokkaido’s seasonal offerings, soaking in the onsen hot springs, and relaxing in post-race relaxation mode!
Based in the heart of the popular Kami-Furano area and near Biei, the Tokachidake Trail Race takes runners on a 20KM or 55KM course around Mt. Tokachidake. The majority of the course takes part on relatively running-friendly terrain, making the longer distance covered less formidable. Don’t forget to sign up for the pre-race barbeque at Hinode Park and indulge post-race in the onsen hot springs!
The outdoors are what keep drawing people – and trail runners – back to Hokkaido. Come and see what it’s all about in the north!
Autumn beckons as the leaves turn and temperatures drop in Nagano…surround yourself in pure nature! Taking place in the most magnificent of natural playgrounds, the Shinshu Togakushi Trail Race is one of Japan’s rising stars in the long list of trail races around the nation.
Push through with that rush of adrenaline as you run along the historical Togakushi trail! Feelin’ spiritual? You’ll find Togakushi Shrine tucked away in the middle of the woods. With a course cutting through the Joshinetsu-Kogen National Park, runners have unparalleled opportunities to see tranquil sides of Japan’s raw beauty!
During the race, experience the serenity of the mountains, deep in the wilderness of Nagano. After the race, reward yourself with a taste of traditional Japan and treat yourself to warm, handmade Togakushi soba.
