Ichinokoshi-sanso (一ノ越山荘)

Ichinokoshi-sanso is a major public mountain hut on the ridgeline between Murodo and Mt. Tateyama (Oyama)—a classic staging point for summit pushes, sunrise starts, and multi-day traverses in the Tateyama–Tsurugi area. It’s designed for throughput and safety on a very busy alpine corridor, not for “lodge comfort.”
