Mt Tokachi

Mt Tokachi (Japanese: 十勝岳) rises above the Tokachi plain in central Hokkaido as one of the most active and visually striking volcanoes in the Daisetsuzan–Tokachi volcanic group. It's a hyakumeizan* mountain defined by fire and wind, a broad, ash‑covered cone scarred by old lava flows, steep gullies and wide slopes of loose volcanic gravel. Its topography is stark and elemental with slopes cluttered with volcanic rock and ash. Even in summer, patches of snow linger on the upper slopes, adding to the mountain’s austere beauty.

​

Mt Tokachi is one of Japan’s most active volcanoes, with many eruptions recorded and summit vents still releasing steam into the cold mountain air. As of writing, it is currently out of bounds due to eruption risk. When open, it is one of the most approachable major volcanoes in Hokkaido, offering hikers a rare chance to walk directly into a living volcanic landscape. The mountain stands at the southern edge of Daisetsuzan National Park, forming a dramatic gateway to the vast alpine world that stretches north towards Mts Asahi (旭岳) and Tomuraushi (トムラウシ山).

​

The views from Tokachi are wide and spectacular. To the east, the Tokachi plain spreads out toward the horizons, to the west, the high volcanic ridges of the Daisetsuzan can be seen prominently, and on clear days, the Pacific glimmers far beyond the foothills. The openness of the terrain means the panorama unfolds almost immediately after the start of the hike.

​

The hiking is straightforward but demanding. Most routes begin from the Tokachidake Onsen area, climbing through scrubby vegetation before emerging onto the bare volcanic slopes. From there, the trail becomes a steady ascent over loose gravel, pumice, and wind‑shaped ridges, with steam vents and sulphurous patches. When I climbed, the acrid smell from the fumaroles was almost overpowering and I nearly turned back. The final approach to the summit is a long, exposed ridge walk, rising gradually toward a broad crest where the wind is constant and the views sweep across central Hokkaido. Weather can change quickly, and the open terrain offers little shelter, making preparation essential.
