Tashirotai, Hakkoda, Aomori
Hakkoda Onsen, Nugudamari-no-Sato
Do not plan a bathing visit in 2026. The inn has remained closed since 2019 and has no announced reopening date. Its four-source system, especially the naturally carbonated Ramune-no-Yu, has historical interest, but none of that represents a currently available bath.
Check before bathing
- Opening hours
- Closed; reopening date not announced. Former day-use hours and prices—10:00–17:00 and ¥600 for the main bath, ¥800 for Ramune Hall or ¥1,000 for both—are pre-closure historical information only.
Spring & water temperature
- Spring-source temperature
- No current 2026 figures are published. Older spring measurements are historical only.
- Bathing temperature
- Unavailable; the facility is closed.
- Spring source
- Four historical springs: Ryujin-no-Yu, Hakkoda Motoyu, Milk-no-Yu and Ramune-no-Yu.
- Spring classification
- The Hakkoda Onsen Association describes Ryujin-no-Yu as a neutral spring and the other three as acidic. Ramune-no-Yu was known for natural carbonation and sulfur.
- pH
- No current 2026 analysis is available.
- Flow rate
- Not published as a current figure.
- Water handling
- The inn is closed, so none of these springs is currently available for bathing here.
Maintain the closure hold until MiK or the Hakkoda Onsen Association issues a formal reopening notice. A hiking-trail reopening does not mean the inn has reopened.
How to read a bath profile
Spring-source temperature and actual bathing temperature are kept separate. Each score is shown independently for comparison rather than collapsed into one overall score.
