Gonoike-goya is one of the most distinctive mountain huts on Mt. Ontake—set just below Hida-chojo (Hida Summit) beside the Gono-ike crater-lake area. It’s famous for combining serious volcano-zone logistics with an unusually “comfortable” hut vibe (including its well-known café).

Ninoike-sanso is a high-altitude mountain hut beside Nino-ike, Japan’s highest-altitude lake, on Mt. Ontake. It’s a classic summit-zone staging base: you use it to split a long Ontake ascent, time sunrise above the cloud layer, and position yourself close to the crater area for early starts. Because Ontake is an active volcano, route access can change with volcanic alerts—so this is a hut where planning and up-to-date checks matter.

Ninoike Hutte is a high-altitude mountain hut located near Nino-ike (Second Crater Lake) on Mt. Ontake, one of Japan’s major volcanic mountains. Its role is very clear: it’s a summit-zone staging base—ideal for splitting a long Ontake ascent, catching sunrise above the cloud layer, and positioning yourself close to the crater-lake area for early starts.

Ishimuro-sanso is a classic high-altitude mountain hut on Mt. Ontake (御嶽山), positioned around the 9th station (Kurosawa-guchi). It’s a strategic staging stop for hikers moving between the ropeway side and the upper crater/summit area—especially useful for splitting the climb, managing fatigue, and timing weather windows on an active volcano where access restrictions can change.

7th Station Gyoba-sanso is a well-known mountain hut on Mt. Ontake (御嶽山), located on the Kurosawa Trail (黒沢口) near the ropeway side. It’s a practical first overnight / staging stop for hikers continuing toward higher huts such as Nyonin-do and beyond—especially useful for pacing, altitude adaptation, and weather-window planning on a volcanic mountain.
