Daisetsuzan Grand Traverse(大雪山縦走)

6d
The Daisetsuzan Grand Traverse is a premier high-altitude wilderness trek in Hokkaido, Japan. This approximately 55km (34 mile) north-to-south route crosses the core of Daisetsuzan National Park—the largest national park in the country. The trail traverses an expansive volcanic alpine plateau characterized by active fumaroles, subarctic meadows, and permanent snow patches. The region provides habitat for the Higuma (brown bear) and the rare pika, offering a true subarctic wilderness environment.
Mission Directive / X-Factor
“The Volcanic Solitude and the First Autumn. The 'X-Factor' of Daisetsuzan is its scale. Unlike the crowded peaks of central Japan, here you can walk for hours without seeing another soul. Reaching the rim of the massive Ohachidaira caldera—a 2km wide collapsed volcanic crater—is a humbling experience. Furthermore, because of its northern latitude and high altitude, Daisetsuzan is the first place in Japan to see autumn colors (Koyo) in mid-September, turning the entire volcanic landscape into a sea of fiery red and burnt orange.”
Hazard Assessment
Hokkaido is home to the Higuma (brown bear), which are larger than Japan’s mainland black bears and require significant wildlife precautions.
MITIGATION: Carry a bear bell and bear spray; utilize bear-proof food storage solutions or high-altitude lockers at designated huts; maintain audibility while transiting through areas of low visibility.
The 'Roof of Hokkaido' is notorious for sudden gales, thick fog, and snow even in summer.
MITIGATION: Carry high-quality thermal and waterproof gear (Gore-Tex); have a GPS with offline maps; know the location of emergency shelters; do not attempt the high ridges if a storm is predicted.
