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.

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.
