About NAMBA Niseko Area Mountain Bike Association

The NAMBA Story

In 2021, six keen mountain bikers in Niseko looked at the mountains around them and asked why nobody was using them in summer. Niseko was a famous winter destination, but when the snow melted, the trails stopped. They decided to change that.
What six riders started in 2021 has become Japan's largest free-access, nonprofit-built mountain bike trail network. Over 21 kilometres of Swiss-designed trails, spanning multiple parks across the Niseko region. All free to ride, every day of the season, no membership or registration required.
NAMBA is not just a bike park. We're behind mountain biking across the entire Niseko area: building and managing Twin Peaks Bike Park, consulting on Grand Hirafu's expansion, opening Hanazono's first trails, designing unified signage systems, and planning the Mt Yotei loop. No other organisation in Japan is doing this at this scale.

Why NAMBA exists

We're riders who got tired of waiting for someone else to build. When the snow melted, Niseko shut down, so we started.
Our own bike parks are free, always: Twin Peaks now, Yotei 360 and alpine trails next, no membership and no gates. We also build at resort partners, where trails ride off their lifts.
What we're working towards: Asia's premier mountain bike region, park by park, season by season.

The Allegra Partnership

Our trails are designed and built with Allegra, the Swiss trail-building firm behind some of the best-known parks in Europe and Asia. That experience shapes every metre of trail at Twin Peaks.

Growth Timeline

2021
Six riders with a question

Six mountain bikers in Niseko look at the mountains around them and see year-round potential. They start figuring out how to build a nonprofit from scratch.

2022
NAMBA is real

Officially founded as an NPO. The founding board comes together. Trail design goes out to tender, and Allegra win by unanimous vote. Kutchan town grants us permission to rent the land that becomes Twin Peaks. COVID visa lead times for Allegra's crew cut the first build window short, but we still finish Ezo Shika and the upper part of Easy Ryder, all built under a 1m trail-width restriction and without cutting down a single tree.

2023
Twin Peaks opens

Our biggest build window yet, the fastest-growing project Allegra had ever seen. Sponsorship is tricky, but every trail finds a backer. We learn (the hard way) that every excavation has to be revegetated before opening, so the community shows up: volunteers building bridges, installing signage, hand-seeding grass. On 16 September, Twin Peaks opens to the public. That summer, Hokkaido hosts its first Soil Searching event. At the closing weekend, Grand Hirafu approach us about building at their resort.

2024
One park becomes two

Work begins at Grand Hirafu: new trail goes in and the existing Kaikan is reworked, with a future link to Twin Peaks in mind. At Twin Peaks, the rocky upper section we'd been wrestling with the year before becomes Taki Tech, the park's first double-black. Dirty Dames launches with 30+ women at the opening ride.

2025
Riders the world over

Cruise Control opens and becomes one of the park's most-loved trails. So does Twin Peaks' first jump line, paired with a dedicated climb trail for hot laps. Loic Bruni visits to ride and to discuss a new project with NAMBA and Nico Vink. Building begins at Hanazono.

2026
A regional network takes shape

Hanazono opens in summer 2026, joining the network. Grand Hirafu shifts operations to the new Ace Gondola, with new singletrack going in. The vision the founders sketched in 2021, one connected Niseko riding region, is becoming the map.
