Senmai-goya (千枚小屋)

Senmai-goya is one of the most important ridge-stage huts on the Southern Alps “big-mountain” corridor that leads into the Arakawa Three Mountains (including Warusawa-dake / Arakawa Higashi-dake). It’s a classic staging base: you use it to split long approach days, control your timing for weather windows, and position yourself for the next day’s higher ridge objectives.
