Mt. Komagatake

A Striking Volcanic Peak Sculpted by History

Rising 1,131 meters above the Oshima Peninsula, this active volcano is known for its jagged ridgeline and broad slopes. Recognized as one of Japan’s New Three Scenic Views, it is one of southern Hokkaido’s most iconic landscapes.

Mt. Komagatake was once a near-perfect conical peak resembling Mt. Fuji. However, a major eruption in 1640 caused the summit to collapse, creating the distinctive silhouette seen today. The mountain now features rugged peaks, including Kengamine and Mt. Sawaradake. Depending on the viewing angle, it can appear either like a sphinx or a graceful solitary mountain. As the symbol of Onuma Quasi-National Park, its seasonal colors reflected in the lakes continue to attract visitors year-round.

Step onto the trail and feel the power of the volcano through the crunch of volcanic gravel underfoot. The fresh scent of larch forests and the rustling of leaves add to the tranquil atmosphere. As you climb higher, expansive views unfold, revealing the blue waters of Lake Onuma and Lake Konuma below. On clear days, the panorama stretches across the Tsugaru Strait to Aomori Prefecture. Surrounded by crisp mountain air, visitors can enjoy spectacular volcanic scenery shaped by the forces of nature.
