Daisetsuzan, Hokkaido Complete Guide: Attractions and Mountaineering Information for Japan’s Largest National Park
Daisetsuzan, which spreads across central Hokkaido, is known as the “Roof of Hokkaido” and is Japan’s largest mountain range. The Daisetsuzan National Park, which covers an expansive area of approximately 230,000 hectares comparable to Kanagawa Prefecture, features peaks of 2,000 meters in elevation, providing a high alpine environment comparable to 3,000-meter peaks in Honshu. This article provides a comprehensive explanation of Daisetsuzan’s nature, geography, mountaineering information, and attractions throughout the four seasons.
Daisetsuzan: Overview and Basic Information
How to Read Daisetsuzan and About Its Name
Daisetsuzan is read as “taisetszan.” This name does not refer to a single specific mountain but rather is a collective term for a group of 2,000-meter-class mountains located in central Hokkaido. To clarify that it is not one mountain, it is sometimes called “Daisetszan-kei” (Daisetsuzan Range) or “Daisetszan Renpo” (Daisetsuzan Chain).
In the Ainu language, it is called “Kamui Mintara (the Garden of the Gods),” and has long been revered as a sacred place. This name aptly expresses the grand and mystical natural environment of Daisetsuzan.
Location and Scale of Daisetsuzan National Park
Daisetsuzan National Park is located in the approximate center of Hokkaido and was designated in 1934 as one of the earliest national parks in Japan. With a total area of approximately 226,764 hectares, it is known as Japan’s largest national park.
The core of the park is the area called Omote-Daisetsu, centered on Asahidake, the highest peak at 2,291 meters in elevation, with mountains such as Hokuchin-dake, Hakuun-dake, and Kurodake arranged around the Ohatira Caldera. Additionally, areas such as the Tokachi Range, Kita-Daisetsu, and Higashi-Daisetsu are included, forming an extensive mountain range.
Regional Divisions of Daisetsuzan and Major Mountains
Due to its vast expanse, Daisetsuzan National Park is divided into several regions. Each region possesses its own distinctive features and attractions.
Omote-Daisetsu (Front Daisetsuzan)
Omote-Daisetsu forms the core of the Daisetsuzan mountain range and is the area visited by the most mountaineers. Major mountains include the following.
Asahidake (Asahi Peak)
At 2,291 meters in elevation, it is Hokkaido’s highest peak and the highest peak of Daisetsuzan. It remains an active volcano, with fumaroles visible near the summit. The Asahidake Ropeway is well-equipped, providing easy access to the Sugata-mi Station at 1,600 meters in elevation, making it popular with mountaineers ranging from beginners to advanced climbers.
Hokuchin-dake (North Pillar Peak)
At 2,244 meters in elevation. The second-highest peak after Asahidake, it is located on the northern side of the Ohatira Caldera. From the summit, spectacular views overlooking the entire Daisetsuzan range spread out.
Hakuun-dake (White Cloud Peak)
At 2,230 meters in elevation. Characterized by a gentle mountain form, it is known as a treasure trove of alpine plants. Access from Sounkyou Onsen (Hot Spring) is typical.
Kurodake (Black Peak)
At 1,984 meters in elevation. Accessible from Sounkyou Onsen via the Kurodake Ropeway and Lift, allowing for day-trip mountaineering. It is a popular mountain.
Chuubetsu-dake (Chuubetsu Peak)
At 1,963 meters in elevation. Located in the source region of the Chuubetsu River, offering quiet mountain travel. The route from Tenjin Gorge Hot Spring is representative.
Tokachi Range (Tokachi Renpo)
A volcanic group located in the southwestern part of Daisetsuzan National Park. The main peak, Tokachi-dake at 2,077 meters in elevation, is a currently active volcano that erupted on a large scale in 1926 and 1962. The range includes mountains such as Biei-dake and Furano-dake and can be accessed from Biei and Kamifurano towns.
Kita-Daisetsu (North Daisetsuzan)
An area extending to the north of the Daisetsuzan range with relatively low elevations and covered in deep forests. It can be accessed from Aizankei Onsen and Sounkyou Onsen, with primitive natural environments preserved.
Higashi-Daisetsu (East Daisetsuzan)
Located in the eastern part of the Daisetsuzan range with rugged peaks such as Nipesotsu-yama and Upepesanke-yama in succession. Many mountains with difficult access are located here, making it known as an area for advanced mountaineers.
Geological History and Geology of Daisetsuzan
The formation of Daisetsuzan began with volcanic activity starting approximately 3 million years ago. The complex topography seen today was formed through multiple eruptions.
History of Volcanic Activity
At the center of Daisetsuzan lies the Ohatira Caldera with a diameter of approximately 2 kilometers. This caldera is believed to have been formed by a massive eruption approximately 30,000 years ago. The structure consists of outer rims such as Asahidake, Hokuchin-dake, and Hakuun-dake surrounding the caldera.
Asahidake remains an active volcano with the most recent recorded eruption in 1739. Fumarole activity is currently visible in the Jigoku Valley (Hell Valley) near the summit, with the smell of sulfur permeating the area.
Traces of Glacial Topography
Numerous landforms believed to have been formed during past ice ages remain in Daisetsuzan. Bowl-shaped formations called cirques (kettle valleys) and moraines are confirmed, and the possibility of past glaciation has been noted.
The volcanic rock composition consists mainly of andesite and dacite, with traces of lava flows and pyroclastic flow deposits observable in certain areas. These geological features tell the story of Daisetsuzan’s complex formation history.
Natural Environment and Ecosystem of Daisetsuzan
Daisetsuzan National Park nurtures diverse natural environments and a rich ecosystem due to its vast area and elevation differences.
Vertical Distribution of Vegetation
Daisetsuzan exhibits clear vertical distribution of vegetation according to elevation.
Lower Mountain Region (Elevation Approximately 500–1,000 meters)
Coniferous forests of Ezo spruce and todo fir spread widely. Deciduous trees such as birch and Mongolian oak mix in, forming rich forests.
Sub-alpine Zone (Elevation Approximately 1,000–1,600 meters)
A forest zone dominated by birch and dwarf pine. Alpine plants begin to thrive in this zone.
Alpine Zone (Elevation Approximately 1,600 meters and above)
Beyond the dwarf pine zone, alpine flower meadows and wind-swept grasslands spread out. Approximately 250 species of alpine plants are confirmed, including Ezo corydalis, mountain avens, and Ezo crowberry.
Snowfields and Rocky Ground
At the highest peaks, perennial snow and snowfields remain even in summer, where plants such as alpine poppy, adapted to extreme environments, grow.
Fauna
Mammals such as brown bears, Ezo deer, red foxes, and flying squirrels inhabit the area. Brown bear population density is particularly high, requiring sufficient caution when mountaineering.
Among birds, alpine species such as Japanese bullfinch, alpine accentor, and hawfinch can be observed. The pileated woodpecker, designated as a national natural monument, also inhabits the region.
Among insects, numerous species unique to Daisetsuzan or Hokkaido, such as the Daisetsu alpine butterfly and pale clouded yellow, are confirmed, making this a biogeographically significant region.
Alpine Flora Paradise
Daisetsuzan is also known as a “flower mountain” where alpine plants burst into bloom simultaneously during the short summer. From late June through early August, flowers bloom in succession depending on elevation, delighting mountaineers.
Representative alpine plants include Ezo corydalis, mountain avens, Ezo crowberry, yellow rhododendron, alpine gold buttercup, bladder-pod, and Japanese spiraea. The alpine plant colonies around Sugata-mi Pond on Asahidake and the flower meadows of Hakuun-dake are particularly magnificent, attracting many photography enthusiasts.
Autumn Foliage at Daisetsuzan: Japan’s Earliest Arrival of Fall
Daisetsuzan is known as “the place where autumn foliage arrives earliest in Japan.” In the alpine zone, foliage begins in late August, reaching its peak from mid to late September.
Scenic Spots and Timing for Autumn Foliage

Ginsentai (Silver Spring Platform) (Mid to Late September)
Ginsentai, the starting point for climbing Akadake, is particularly famous as a foliage viewing spot. The mosaic-like scenery created by the green of conifers and the red and yellow of deciduous trees spreads out. Traffic restrictions are implemented during foliage season, with access via shuttle bus.
Since foliage coloring is greatly influenced by temperature, it is recommended to check the latest foliage information before visiting. The Daisetsuzan National Park Liaison Council’s website updates real-time foliage information.
