Water and bathing details for Nagato Onsen
Facility-level figures; blank town-wide averages are not inferred.
Named facility records for Nagato Onsen. Figures marked “Not published” are not treated as town-wide averages.
| Facility | Spring | Source data | Supply | Bath type |
|---|---|---|---|---|
| Hakuen-no-Yu, Tawarayama Onsen | Alkaline simple hot spring (low-tonicity, alkaline). Kawa-no-yu's analysis dates to 2013. Source: Kawa-no-yu spring in Bath No. 1; a blend of five Tawarayama springs in Bath No. 2 and the outdoor bath. | Source temperature: 41.1°C for Kawa-no-yu (2013 analysis); no single source temperature is published for the five-spring blend used by Bath No. 2 and the outdoor bath. pH: 9.9 for Kawa-no-yu (2013 analysis). The district-wide pH 9.8 is a separate figure and is not substituted for this facility. | Bath No. 1 uses source-flowing Kawa-no-yu. Bath No. 2 and the outdoor bath use a blend from five Tawarayama springs. Current main text pages do not fully publish water addition, heating, circulation or disinfection details pool by pool. | Day-use bath. A good choice for an outdoor bath, a spacious bathing area and an easy-to-visit facility. Keep the source-flowing No. 1 bath distinct from the five-source blend used in the No. 2 bath and outdoor bath. |
| Machi-no-Yu, Tawarayama Onsen | Alkaline simple hot spring (low-tonicity, alkaline); both springs were analysed in 2013. Source: Machi-no-Yu spring for the public bath; Shono-yu spring for the private family bath and drinking spring water. | Source temperature: 41.3°C for the public-bath Machi-no-Yu spring; 36.4°C for the separate Shono-yu spring used by the private family bath and drinking-water system. pH: 9.9 for both springs in their 2013 analyses. The Tawarayama district-wide pH 9.8 is a separate figure. | The public bath uses source-flowing water from the spring emerging on site. The private family bath uses the separate Shono-yu spring. Current main text pages do not fully publish water addition, heating, circulation or disinfection conditions pool by pool. | Day-use bath. The clearest pick for spring-water details, local bathing culture, early or late hours and a low-cost soak. Treat the private family bath as a separate spring system from the public bath. |
| Hotel Yokikan | Alkaline simple spring; clear, colourless and odourless Source: Yuyawan Onsen; the hotel's current main text does not give the individual source name | Source temperature: Not published pH: 9.8 | The hotel confirms natural hot-spring water in Genso no Yu, Yokihi no Yu and the family baths. Current main official information does not give complete bath-by-bath water-treatment details. | Ryokan. A strong day-trip choice for drivers pairing the bay-view bath with Tsunoshima, Motonosumi Shrine or Senjojiki. Choose elsewhere if low admission or fully published water-treatment details matter most. |
