The trail to Ichankoppe‑yama (828 m) begins from a small parking area along the northern shore of Lake Shikotsu, immediately entering mixed forest dominated by birch, spruce, and dense sasa. The path climbs steadily from the start, following a well‑cut spur that rises above the lakeshore. Early on, short openings in the trees offer glimpses of the deep blue water below and the broad caldera walls surrounding the lake.

As the first spur gains height, the trail flattens out and we traverse across just below the crater rim where we reach a saddle. The forest gradually thins and the views begin to open. The trail maintains a consistent, moderate gradient, weaving through alternating bands of conifer and dwarf bamboo before emerging onto a series of airy clearings. These mid‑ridge viewpoints are a highlight of the route, offering sweeping panoramas across Lake Shikotsu toward Eniwa‑dake, Fuppushi‑dake, and the volcanic skyline of the Shikotsu‑Toya National Park.

The final approach to the summit is gentle and scenic, following a broad, grassy ridge with uninterrupted views of the lake. The summit of Ichankoppe‑yama is spacious and open, providing one of the best vantage points in the region: a full caldera panorama, the rugged profile of Eniwa‑dake to the south, and the long ridgeline stretching toward Mt. Soranuma and the Sapporo mountains to the north.

After enjoying the summit, hikers return via the same route, descending the ridge back toward the lakeshore. The trail is straightforward and well‑defined, making Ichankoppe‑yama an excellent choice for a half‑day outing with big scenery and minimal technical difficulty.

Ichankoppe‑yama is one of the most rewarding low‑elevation peaks around Lake Shikotsu — a perfect introduction to the region’s volcanic landscape and a reliable early‑season hike when higher mountains are still holding snow.
