Guide
What visitors add
Price
Admission is 600 yen (four reviewers, Feb-Apr 2026); one specifies it buys a 3-hour stay, and reviewers consistently call it cheap for what you get.
stated by 4 visitors · Feb 2026 – Apr 2026Price
Several discounts are reported: JAF members get 10% off (two reviewers; a third mentions the JAF discount without the rate), one reviewer notes a mont-bell member discount, and one encountered a day-of-week special (men 10% off that day).
stated by 4 visitors · Feb 2026 – Aug 2026The water
The indoor bath is a sodium-calcium chloride spring (one reviewer names the type; a second says the facility draws two sources — chloride indoors, simple spring outdoors). Reviews conflict on the outdoor bath: that second reviewer calls it a simple spring, while a third suspects 'the outdoor bath doesn't seem to be onsen'. The indoor water is colorless with at most a faint scent and gentle on the skin.
stated by 4 visitors · Feb 2026 – Apr 2026Outdoor bath & sauna
Lineup: a large indoor main bath, a small Himalayan rock-salt bath (rock salt is added several times a day per what one reviewer was told; a second mentions the salt bath), one outdoor bath, and a sauna (two reviewers). The outdoor area also has washing stations; one reviewer found indoor washing stations few relative to the locker capacity.
stated by 4 visitors · Feb 2026 – Aug 2026Outdoor bath & sauna
The outdoor bath is small (one reviewer) and on the cool side, but open-feeling with mountain views, and two reviewers specifically praise stargazing from it at night.
stated by 4 visitors · Feb 2026 – May 2026The water
Temperatures: one reviewer measured the indoor bath at about 42°C and the outdoor at about 38°C; another says the facility keeps the water at an average 41°C and finds it very warming; a third simply calls the outdoor bath lukewarm.
