Hütte O-yari is a classic ridge-stage hut located on Higashi-Kama-one, the ridge line that links Mt. Yarigatake and Mt. Nishidake. Its biggest appeal is its position: close enough for a practical summit push, but far enough to feel quieter than the main summit hut zone—often described as “not too close, not too far” from Yarigatake.

Yari-gatake-sanso is one of the most iconic and largest mountain huts in the Northern Japanese Alps, sitting just below the summit of Mt. Yarigatake (3,180 m). It’s a true high-alpine hub: a summit staging base, a traverse junction (Omote-Ginza and Yari–Hotaka routes), and a logistics powerhouse with major services compared to smaller ridge huts.

The Yarisawa Lodge (槍沢ロッヂ) is a classic forest-zone mountain lodge positioned at the midpoint of the main hiking route from Kamikōchi to Mt. Yarigatake. Operated by the Yarigatake Sanso Group, it’s designed as a high-throughput staging base: a comfortable, efficient stop to split the approach, manage timing, and push higher the next day toward Sesshō Hyutte and the summit ridge.

Sesshō Hyutte is a historic mountain hut located in the Sesshō-daira area just below Mt. Yarigatake (槍ヶ岳). It’s widely used as a staging base for the final summit push, and as a practical stop on long traverses such as the Omote-Ginza and routes connecting into the Yari–Hotaka region.
