△Somewhere to sit — A small rest area

Japan's highest hot spring, at 2,410m on the Murodo plateau, on strongly acidic water at pH 2.28 running 100% free-flowing from Jigokudani next door. Indoor tubs only - there is no open-air bath, which is why the view score is held down despite the setting. Everything around it is national park: Mikurigaike pond, the Jigokudani steam vents and the Raichozawa trails are all on the doorstep. Open roughly mid-April to late November and shut all winter.

Every onsen on this site is scored against the same written rubric, and every score has been reviewed by the editor. The ones marked Visited were also bathed in personally.

Getting there
The highest hot spring in Japan, at 2,410m on the Murodo plateau in the Northern Japan Alps. No road reaches it: you take the Tateyama Kurobe Alpine Route from either the Toyama or the Nagano side to Murodo Terminal, then walk about 15 minutes on a stone-paved path with steps and slopes. In April and May that path is through deep snow. Wheelchairs cannot make it. The altitude is high enough that altitude sickness is a real risk, and the inn advises anyone with diabetes, high blood pressure or heart conditions to consult a doctor first, because emergency response up here is difficult.
