Echizen Onsen Nihonkai Open-Air Bath
Choose it for an early soak with views of the Sea of Japan. Weekend and holiday bathing starts at 07:00, but the official pages disagree on closing days, so check before driving out.
Check before bathing
- Opening hours

- Tattoo policy
- Tattoos are not permitted.
Spring & water temperature
- Spring-source temperature
- Not confirmed; the operator's 40.1°C figure is tied to the conflicting source identification.
- Bathing temperature
- Not published.
- Spring source
- Echizen No. 3 spring (Nambu Onsen), based on Echizen Town's 11 January 2024 survey.
- Spring classification
- Sodium chloride-bicarbonate spring; low-tonicity, weakly alkaline and cool spring.
- pH
- No facility-specific figure is published; the operator's 7.15 value is not used because its source identification conflicts with the town survey.
- Flow rate
- Not published.
- Water handling
- Natural spring water is used in the indoor and outdoor baths. The operator's static technical panel names a different source (Echizen No. 2) and gives conflicting figures, so its treatment details are not adopted as current pool-specific facts.
- Analysis date
- 2024
Bathing indications
The town lists general bathing indications including neuralgia, muscle and joint pain, frozen shoulder and motor impairment. These are not a treatment guarantee.
The operator and town tourism page disagree on weekly closures. Confirm the current schedule, particularly before a long drive.
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.
