Named facility records for Hirugami Onsen. Figures marked “Not published” are not treated as town-wide averages.
| Facility | Spring | Source data | Supply | Bath type |
|---|---|---|---|---|
| Yuttarina Hirugami | Hirugami Onsen water. The regional tourism bureau classifies the area as an alkaline simple sulfur spring, but the facility's current main pages do not publish a matching, up-to-date analysis certificate. Source: Hirugami Onsen distribution system; the current main facility page does not identify a specific source well for this bathhouse. | Source temperature: Not published for this facility. Hirugami's regional figure of 47.4°C is not assigned to its baths. pH: Not published. | Current 2026 facility information lists indoor and open-air baths, a sauna, waterfall shower, reclining and sitting baths, and a swimming pool. Complete pool-by-pool details on water addition, heating, circulation, disinfection and source flow are not published, so no treatment method is inferred. | Day-use bath. A dependable first stop in Hirugami if you need the longest opening window, family swimming, a sauna or an assisted/family bath. For a quieter feel or more rural scenery, look at Achi-no-Sato or Hirugami-no-Mori. |
| Hirugami-no-Mori Hotel Day-Use Bath | Alkaline simple spring, according to the facility's current description. Source: Hirugami Onsen; an individual spring-well name is not published. | Source temperature: Not published. pH: Not published. | The facility confirms Hirugami Onsen water in its large bath and open-air bath. Water addition, heating, circulation, disinfection and source-flow conditions are not published pool by pool. | Day-use bath. Best for an afternoon arrival when an elevated open-air bath and seasonal views matter most. It is not the best fit for an early soak, a low budget, guests with tattoos or anyone relying on a fixed weekly closing day. |
| Achi-no-Sato Hirugami Day-Use Bath | Alkaline simple sulfur spring, according to the facility's current description. Source: Hirugami Onsen; an individual spring-well name is not published. | Source temperature: Not published. pH: Not published. | The facility explicitly says its natural spring water is used without adding water. It offers indoor, open-air and herbal baths. Heating, circulation, disinfection and the source-flow conditions of each individual pool are not fully published. | Day-use bath. A strong choice if you prefer a smaller bathhouse, a quiet green setting, basic amenities and accessibility information. Check the last admission time for an evening visit and seasonal notices before relying on the outdoor baths. |
