Shiobara, Nasushiobara, Tochigi Prefecture
Shiobara Akatsuki-no-Yu
The most practical choice if you want to combine bathing, a place to rest, food and even a warm-water pool in one stop. If you are looking only for a gorge-side source-flowing bath or a remote onsen feel, there is no need to detour to Sekiya.
Check before bathing
- Opening hours
- 10:00–22:00; closed on the third Wednesday of each month.
Spring & water temperature
- Spring-source temperature
- Not published; older analysis figures from the 2000s are not substituted as a 2026 source temperature.
- Bathing temperature
- No fixed pool temperature is listed in current official information.
- Spring source
- The facility's own spring; the current official tourism page does not publish a spring name that can be matched to 2026.
- Spring classification
- Not published in the current first-party listing; a complete spring classification is not provided.
- pH
- Not published.
- Flow rate
- Not published.
- Water handling
- Nasushiobara's tourism agency identifies the facility as a source-flowing day-use onsen. The current page does not publish all water addition, heating, circulation and disinfection conditions for every pool, so “source-flowing” is not expanded into a claim that every bath is untreated.
Bathing indications
The official tourism page presents the natural spring alongside rest, dining and a warm-water bathing pool. No medical claim is made here.
The official tourism listing gives weekday adult admission at ¥800 and a weekday evening rate of ¥600. A complete 2026 weekend and holiday price table was not confirmed in the same-strength first-party sources; check the latest facility rates before visiting.
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.
