Mt Nipesotsu

Mt Nipesotsu (Japanese: 二ペソツ山) is a nihyakumeizan* that rises sharply above the eastern edge of Daisetsuzan National Park, a rugged volcanic peak that feels both remote and imposing even within Hokkaido’s vast mountain country. Although not the tallest summit in the region, its steep ridges, exposed rock faces and dramatic volcanic structure make it one of the most striking mountains in the range. It is often called the phantom hyakumeizan because many believe that Kyuya Fukada would have included it had he been able to scale its peak.

​

Topographically, Nipesotsu is defined by its sharp, rocky spine, a rugged ridge that rises abruptly from deep forested valleys. The lower slopes are wrapped in dense conifer and birch, but the upper mountain is stark and alpine with broken volcanic rock, steep gullies and exposed ridgelines that demand careful footing. This dramatic structure reflects the mountain’s volcanic origins, with old lava domes and weathered cliffs giving it a raw, elemental character.

​

The views from the summit are among the finest in eastern Daisetsuzan. To the west, the great volcanic plateau of the national park spreads out in a vast, rolling expanse; to the east, the Tokachi plains stretch toward the horizon; and to the north, the ridges of the Nipesotsu–Shirane group. On clear days, the panorama feels immense, with the highlands of central Hokkaido unfolding in every direction. Flora on Nipesotsu reflects its high‑latitude alpine environment. The upper slopes host hardy plants that cling to volcanic gravel. Lower down, the forests shelter Hokkaido deer, foxes, brown bears and a rich variety of birds that thrive in the cool mountain climate. In early summer, patches of lingering snow contrast beautifully with the emerging alpine flowers.

​

The hiking course to Mt. Nipesotsu is long, demanding, and deeply rewarding. Most hikers including me climb from the Horoka Onsen area, climbing steadily through forest before reaching the exposed upper ridges. As you rise above the treeline, the mountain’s dramatic form becomes clear. You follow a seemingly endless rugged ridge leading toward a sharp, rocky summit.
