This route covers 55km return.It involves around 3,200m of cumulative elevation gain.
The route reaches roughly 2,291m at its highest point. While the altitude is moderate, weather exposure and wind can make conditions feel more demanding than the elevation suggests.
Technically, the Daisetsuzan Grand Traverse (大雪山縦走) standard trail is challenging. The primary difficulty is the sustained physical effort required or technical terrain features.
Overview
Technical Summary
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 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.
The 'Roof of Hokkaido' is notorious for sudden gales, thick fog, and snow even in summer.
The Expert Take
Success on this route requires balancing physical stamina with environmental awareness.Local conditions shift rapidly; always verify forecasts with regional authorities before moving to higher ground.
Stage Breakdowns
Asahidake to Hakuun-dake
Accessing the northern trailhead via the Asahidake Ropeway. Ascending Mount Asahidake (2,291m) among active fumaroles. Trekking toward the Hakuun-dake Refuge.
The Core Plateau
Traversing the central volcanic plateau toward Chuubetsu-dake and the southern peaks.
Kuro-dake and Sounkyo
Passing the Kuro-dake Hut and descending to Sounkyo Onsen via the Kuro-dake Ropeway. Finishing with a soak in a natural volcanic hot spring.

Technical Specs
Access & Logistics
Regulations
While no entry permit is needed, you must submit a trekker registration form at the trailhead or police station. Huts are unstaffed but have donation boxes.
Seasonality
Very short season (July-September). Snow remains on the trails until late June and can return by late September. Volcanic activity and trail access regulations are dynamic and subject to change; verify with the Daisetsuzan Volunteer Center or local park authorities before departure.

Route Questions
Can I drink the water?
Only from designated springs or treated sources. Some streams in the park contain volcanic minerals or may be affected by local wildlife activity. Always use a high-quality filter or treatment method.
