Also known as: Niseko United MTB, NAMBA
Mt Yotei ('Ezo Fuji') volcano views, birch and hardwood forests, farmland; volcanic scenery a constant backdrop.

Whether everyone in your group gets a day at Niseko (NAMBA network) - the grades on offer, the named zones, and how mixed abilities split up.
Green (easy), Blue (intermediate), Black (advanced); Swiss (Allegra) trail-grading conventions.
Group split by grade at each park: beginners on green flow, advanced on black technical lines; Grand Hirafu offers lift/gondola uplift while Twin Peaks and Hanazono are mainly pedal-access loops.
Excellent for all levels and families; free public access lowers the barrier. Good for mixed groups splitting across grades.
Purpose-built forest singletrack: bermed flow lines plus rocky, rooty technical trails; farmland and forest on longer loops.
Professionally built spread from friendly flow to gnarly, rocky expert lines; generally low exposure with progression-friendly design.
Signed, graded trailheads with maps; NAMBA maintains signage across the parks. Trailforks recommended for the wider network.
Growing but generally uncrowded; described as an emerging Asian riding mecca. Free access draws steady summer riders.
Twin Peaks open approx May 1 to Oct 31; overall network May through October.
Green season, roughly May to October.
Summer wildflowers and Mt Yotei volcano views; the planned Yotei 360 (50 km-plus) loop circling Mt Yotei is a future highlight. -
