Mt Kuro

Mt Kuro (Japanese: 黒岳) on the eastern side of the Daisetsuzan massif, is one of the most approachable yet dramatic volcanic peaks in Hokkaido. It's about 2 hours walk above the ropeway station of Sounkyo, forming the first major summit on the great volcanic arc that continues toward Mt Hakuun (白雲岳) and beyond. Its topography is unmistakably volcanic with broad rocky slopes, scattered lava blocks and a high ridgeline that curves around the rim of a vast crater basin. Because it sits at the gateway to Daisetsuzan’s interior, Mt Kuro offers one of the clearest introductions to the scale and openness of Japan’s largest national park.

​

Mt Kuro is the classic first summit for hikers entering Omote‑Daisetsu. The crater basin below the summit is an immense, bowl‑shaped hollow carved by ancient eruptions and reveals the volcanic origins of the entire range. It's a mountain that stands at the threshold between active volcanic terrain and the long, eroded highlands deeper in Daisetsuzan. The crater itself is the most striking feature: a huge amphitheatre of volcanic debris, snowfields lingering well into summer and ridges that curve in a circle around its rim. 

​

Most hikers including me begin at the Sounkyo Ropeway climbing up a steep but straightforward trail before reaching the rocky summit and the open volcanic slopes. The real attraction lies beyond the peak.  I recommend the loop hike around the crater, which transforms the climb from a simple summit ascent into a full volcanic journey, with shifting views into the crater and outward across the Daisetsuzan highlands.
