Niseko’s Ascent: Unpacking Japan’s Premier MTB Destination
Niseko’s journey to becoming a mountain biking powerhouse is guided by a clear and ambitious vision. The Niseko Area Mountain Bike Association (NAMBA), a non-profit entity, is spearheading this transformation, aiming to establish Niseko as a world-renowned mountain biking community. Their conceptual master plan, developed in collaboration with Swiss trail builder Allegra Tourism, envisions an expansive network of trails that will eventually connect Niseko’s five resorts, neighboring towns, and even feature a loop course around the iconic Mt. Yotei. This long-term project, anticipated to take 20 years to complete, seeks to broaden the appeal of mountain biking beyond extreme sports, making it accessible and enjoyable for everyone. Currently, Niseko boasts over 20 kilometers of trails, with plans to expand to 30 kilometers by phase three, firmly setting its course to host Japan’s largest mountain bike park.
Twin Peaks Bike Park: The Free-Access Frontier
At the very core of Niseko’s burgeoning mountain biking landscape is the Twin Peaks Bike Park, proudly managed by NAMBA. This world-class facility distinguishes itself as Japan’s largest free-to-use, pedal-access trail center. Since its initial opening in Summer 2021, the park has seen continuous expansion, now featuring 14 trails spanning approximately 13 kilometers. Riders can explore a diverse array of experiences, including flowing trails, classic enduro descents, challenging technical sections, dedicated skill loops for practice, and uphill trails. The park provides detailed trail statistics, including specific names like Jinja Ninja (Easy), Easy Ryder (More Difficult), Shogun Syndicate (Very Difficult), and Taki Tech (Extremely Difficult), along with their respective lengths, climbs, and descents. Looking ahead, as of February 2025, future development plans for Twin Peaks include the addition of a new jump line, a green uphill and downhill trail, and several new trail connections, further enhancing its appeal for riders across all skill levels.
Grand Hirafu & Koropokkur: Lift-Accessed Thrills & Family Fun
Complementing the pedal-powered Twin Peaks, Niseko’s major resorts offer convenient lift-accessed mountain biking, enriching the overall riding experience.
Grand Hirafu has revitalized its MTB Bike Park, which is now accessible via gondola lifts during the green season. It features a “Flowtrail” designed with gentle and steep slopes, banks, and turns that mimic the fluid sensation of skiing or snowboarding, providing an unexpected layer of enjoyment for winter sports enthusiasts. The upper section of this Flowtrail operates from July 19th to August 31st, 2025, while the lower section runs from May 31st to September 29th, 2025. Grand Hirafu also provides a free “Skill-up area” tailored for beginner and intermediate riders, with mountain bike rentals readily available. Various gondola and lift passes are offered, including daily and season passes, to facilitate access. The Hirafu Summer Gondola operates from July 13th to September 23rd, providing access to thrilling courses and connections to the Twin Peaks trail, further integrating the region’s network.
Koropokkur Bike Park focuses on providing beginner-friendly experiences and family enjoyment. For 2025, Koropokkur is undergoing Phase 2 construction, which involves expanding the park with an intermediate flow trail, a new freeride trail, and enhanced dirt jump sections. Additionally, new features such as boardwalks, seesaws, and rock sections are being added. Koropokkur also offers local discounts and improved bike wash facilities for visitor convenience. The park operates from May 31st to October 13th, 2025, with specific weekday and weekend schedules. Further details indicate that Koropokkur (also known as Niseko Bike Park) features 9 trails (6 single tracks, 3 double tracks), with a total course length of 2.4 kilometers, alongside various skills areas including a pump track and dirt jumps.
The combination of both free pedal-accessed trails at Twin Peaks and paid lift-accessed resort trails at Grand Hirafu and Koropokkur provides a compelling advantage for Niseko. This dual-access model offers riders the flexibility to choose based on their preference, skill level, and budget – from the self-powered exploration and challenge of Twin Peaks to the convenience and gravity-fed thrills of resort downhill. This versatility caters to a broader spectrum of mountain biking enthusiasts, allowing Niseko to capture a larger market share within the global mountain biking community. It also establishes a more sustainable tourism model by diversifying revenue streams, making the overall mountain biking offering more resilient and appealing.
Niseko’s Claim to Fame: A Comparative Edge
While other regions in Japan offer mountain biking experiences, Niseko’s rapid development and comprehensive master plan uniquely position it to become the country’s largest and most diverse mountain biking destination. Twin Peaks is already recognized as Japan’s largest free-access trail center. While Minami-Alps Tatenuma MTB Park is also cited as Japan’s largest
free MTB park with a total length of approximately 3 kilometers, NAMBA’s Twin Peaks boasts 13 kilometers of trails, making Niseko’s claim to the “largest free” highly credible for a single park entity.
For comparison, Fujimi Panorama in Nagano offers three downhill courses (A, B, and C) with lengths of 4.2 km, 5.2 km, and 7.2 km respectively, totaling around 16.6 km of downhill trails. However, some reports indicate issues with trail condition and occasional closures. Hakuba Iwatake MTB Park features 10 trails with a total distance of 13 miles (approximately 20.9 km). Nozawa Onsen offers a 10-kilometer mountain bike tour down Mt. Kenashi.
Niseko’s unique blend of extensive free-access pedal trails at Twin Peaks, combined with lift-accessed resort trails at Grand Hirafu and Koropokkur, and an overarching vision to connect the entire region, sets it apart. The sheer scale of NAMBA’s 20-year master plan, aiming for trails connecting five resorts and a Mt. Yotei loop suggests a future network that will significantly exceed current Japanese offerings in terms of interconnectedness and overall length. This ambitious future vision, coupled with the rapid rate of expansion (e.g., 30 kilometers by Phase 3), clearly indicates Niseko’s trajectory and commitment to becoming the preeminent mountain biking destination in Japan. For Australian tourists, this means Niseko is not just a current world-class destination but one with immense, ongoing future growth. This promises new trails, expanded experiences, and a continually evolving scene for return visits, positioning Niseko as a forward-thinking, dynamic destination that appeals to riders who wish to be part of an emerging and ambitious mountain biking hub.
