Masago-sawa Lodge (真砂沢ロッジ)

The Masago-sawa Lodge (真砂沢ロッジ) is a small, remote valley-stage lodge deep in the Tateyama–Tsurugi area. It sits in the lower Tsurugi-sawa corridor and is most commonly used as a strategic overnight on the Tsurugi-sawa route, where hikers transition from long approach stages into more committing alpine terrain.
