Mt Jukkoku

Mt Jukoku (Japanese: 十石山) has become a popular peak in recent years. It was once known mainly to locals but is now drawing back‑country skiers, spring mountaineers and hikers who appreciate its raw, snowy beauty. Because it can only be accessed from Shirahone Onsen, which is at the end of a steep road off the main road to Kamikochi, the mountain retains a sense of remoteness. The approach road is steep, narrow and often icy, so it’s best to wait until March, when winter finally loosens its grip and the route becomes reliably passable.

​

The climb itself is long, hard, and wonderfully atmospheric. You begin deep in the forest, ascending steep slopes that seem to rise endlessly until you suddenly break through the treeline. From here the character of the mountain changes completely. A wide, steep snow valley opens above and you climb directly up its face. In good conditions the snow is firm and supportive, making the ascent feel clean and direct.

​

The summit delivers one of the finest 360‑degree panoramas in the region. Mt Norikura (乗鞍岳) stands close by, its volcanic shoulders still holding late‑season snow. Across the valley rises Mt Yake (焼岳)　and behind it the jagged skyline of the Hotaka range (穂高連峰) cuts sharply into the sky. 

​

I climb Jukoku every year, almost always in the remaining‑snow season. The combination of difficult access, steep forested ascent, open snow valley, and vast summit views makes it one of the most rewarding spring peaks in the region.
