Kuranosuke-sanso (内蔵助山荘) is a small, traditional high-ridge mountain hut positioned just below Mt. Masago-dake in the Tateyama–Tsurugi area of the Northern Japanese Alps. It’s best used as a serious stage hut—a place to sleep, reset, and time weather windows—rather than a comfort lodge. Its big value is panoramic ridge positioning and access to committing Tateyama ridgeline itineraries.

Tsurugi Gozen-goya is a major public mountain hut on the Tateyama–Tsurugi ridgeline, sitting at Bessan Norikoshi—one of the most famous viewpoints of Mt. Tsurugi (剱岳). It’s a high-traffic stage hut and base for parties aiming at Tsurugi-dake, as well as trekkers linking Tateyama-area routes.

Raicho-sou is a large mountain lodge with natural hot-spring baths located near the Murodo-daira plateau in the Tateyama area. It’s best used as a comfort-forward base for Tateyama day hikes and plateau exploration—more “alpine lodge” than minimalist ridge hut, with strong infrastructure and easy access from the Alpine Route hub.

Raicho-sawa Hütte (雷鳥沢ヒュッテ) is a large public mountain hut in the Murodo / Tateyama area, set in the flower-filled basin of Raichōzawa after you pass Mikurigaike and Jigokudani (Hell Valley). It’s famous for having a hot-spring bath and for functioning as a practical base camp for day hikes and traverses around Tateyama.

Mikuri-gaike Onsen is a mountain lodge with a natural hot spring on the Murodo-daira plateau in the Tateyama area. It’s widely known as Japan’s highest-altitude hot spring lodge, drawing its waters from Jigokudani (Hell Valley) and sitting a short walk from the Murodo transport hub—making it a rare combination of high altitude + real onsen comfort + easy logistics.

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.”

The Yakushi-dake-sanso (薬師岳山荘) is a classic high-alpine mountain hut located just below the summit of Mt. Yakushi-dake (2,926 m) in the Northern Japanese Alps (Toyama side). It functions as a summit base and traverse-stage hut for hikers tackling Yakushi-dake and linking longer interior routes across the Tateyama–Yakushi–Kurobe network.

The Tateyama-Murodou-sanso is a large public mountain lodge located on the Murodo plateau, the central high point of the Tateyama–Kurobe Alpine Route. More lodge than “ridge hut,” it functions as a logistics-and-comfort base for hikers heading to Mt. Tateyama (Oyama) and for trekkers stitching together multi-day itineraries across the Tateyama highlands.

The Goshiki-gahara-sanso is a classic Japanese mountain hut set in the Goshiki-ga-hara plateau area near Mt. Tateyama, famous for its volcanic terrain, sulphur vents, and the “five-coloured” landscape that gives the area its name. It functions primarily as a stage hut and destination base for hikers exploring the Tateyama highlands—more about plateau exploration and scenery than summit-only objectives.
