Kawatana Onsen, Toyoura, Shimonoseki, Yamaguchi Prefecture
Kawatana Onsen Peaceful Seiryusen
A strong practical choice if you want low-cost bathing, functional baths, a family bath and well-documented spring data in one place. The focus is utility rather than a seaside or station-front setting.

- Water handling
- The Toyoura tourism association describes the public baths as source-flowing, and the facility says its family baths are source-flowing. The facility adds heat only during colder weather to maintain a suitable temperature and uses chlorine-based chemicals for hygiene. Current main pages do not fully specify water addition or circulation conditions for each pool.
Bathing indications
The facility lists spring-specific indications including cuts, peripheral circulation problems, sensitivity to cold and dry skin. These are general hot-spring indications, not a promise of personal treatment effects.
The facility states that it heats the water during colder weather and uses chlorine-based chemicals for hygiene. It does not fully publish water addition or circulation details for each pool.
Keep the 42.8°C source temperature separate from the 41.1°C point-of-use figure. The latter is not a fixed temperature for every outdoor, family or functional bath. Even where a bath is described as source-flowing, the facility explicitly notes seasonal heating and chlorine-based disinfection. The large public bath does not provide soap, shampoo or towels.
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.
