A Tsurugi-dake Hayatsuki-goya (早月小屋) é a única hut instalada na longa e famosa Hayatsuki Ridge (早月尾根), um dos acessos mais duros e diretos ao Mt. Tsurugi-dake (剱岳). Aqui a função é clara: parar, recuperar e gerir o timing antes de um dos trechos finais mais exigentes do dia (ou de um itinerário de 2 dias).

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.

Tsurugi-sawa-koya (剱沢小屋) is a historic, high-mountain hut in the Tateyama–Tsurugi area, widely used as a base and stage hut for parties aiming at Mt. Tsurugi-dake (剱岳) and related ridge itineraries. Its value is strategic: it sits in the core approach zone where hikers transition from plateau logistics to serious alpine terrain.

Kenzan-so is the best-known high-mountain base hut for Mt. Tsurugi-dake (剱岳)—positioned to support early summit pushes, route planning, and safe timing on one of Japan’s most serious “rock-and-exposure” mountains. It was rebuilt in 2007, and is known for unusually “comfortable” infrastructure by Japanese hut standards (e.g., modern toilets and shower facilities).

The Dainichi-daira Sanso (大日平山荘) is a mountain hut on the Dainichidaira plateau in the Tateyama range (Toyama). It’s best understood as a stage hut: a practical overnight that breaks up long approaches between the Shōmyō Gorge / valley side and the higher ridgelines leading toward the Dainichi peaks and Tateyama backcountry.

Dainichi-goya is a compact, route-focused mountain hut in the Tateyama range (Toyama Prefecture), positioned for hikers crossing the more remote ridgelines west of the main Murodo hub. It’s best treated as a true stage hut—a practical overnight that supports long ridge days and weather-window planning rather than comfort-driven stays.

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.
