Daisetsuzan National Park (大雪山国立公園, Daisetsuzan Kokuritsu Kōen) is the largest national park in Japan, encompassing a sprawling wilderness in central Hokkaido that is larger than some of the country’s prefectures. Known as the “Roof of Hokkaido,” this mountainous expanse is defined by its rugged volcanic peaks, high-altitude marshlands, and ancient forests. Its name translates to “Great Snowy Mountains,” a fitting description for a landscape where snow often lingers on the highest ridges well into the summer months.
To the indigenous Ainu people, the park is revered as Kamui Mintara, or “The Playground of the Gods.” This spiritual connection is evident in the park’s untouched scale, which provides a vital sanctuary for Hokkaido’s iconic wildlife. While the local population of Ussuri brown bears is the most famous, the park is also one of the few places in Japan to spot the northern pika. These small, rabbit-like “living fossils” have inhabited the rocky alpine slopes since the last Ice Age and are a prized sight for nature enthusiasts.
Daisetsuzan is renowned for being the first location in Japan to experience the changing of the seasons. Due to its northern latitude and high elevation, autumn colors typically ignite the slopes as early as mid-September, creating a vibrant mosaic of red and gold long before the rest of the country begins to cool. From the active smoking vents of Mount Asahidake—Hokkaido’s highest peak—to the remote, steaming hot spring valleys of Sounkyo, the park offers a raw and primordial experience of Japan’s volcanic power. Its sheer magnitude ensures a sense of profound solitude for those traversing its expansive network of trails and plateaus.
