Spring information
Water and bathing details for Sukayu Onsen
Facility-level figures; blank town-wide averages are not inferred.
Named facility records for Sukayu Onsen. Figures marked “Not published” are not treated as town-wide averages.
| Facility | Spring | Source data | Supply | Bath type |
|---|---|---|---|---|
| Sukayu Onsen Inn | Acidic, sulfur-bearing spring systems. The facility operates five distinct sources; the classification should not be treated as a single identical analysis for every bath. Source: Five springs in total: four supply the Hiba Sennin Bath and a separate spring supplies Tamano-yu. | Source temperature: 52.3°C is listed as a spring temperature by Aomori Prefecture tourism information; it does not represent all five sources or every bath. pH: Aomori Prefecture flags pH 1.5–2.0 as an example of the strongly acidic water; this is not a confirmed shared analysis for all five sources. | The operator confirms five sources but does not publish a complete pool-by-pool breakdown of dilution, heating, circulation or disinfection. | Day-use bath. A destination bath for visitors who want the strongly acidic waters and the cypress-built Hiba Sennin Bath. The large bath is mixed-gender, with a women-only hour and facility-approved bathing wear; Tamano-yu is a separate gender-segregated option. Winter access is better planned around the JR bus than a difficult drive. |
| Hakkoda Hotel | A third-party facility listing identifies Arakawa Onsen as an acidic iron-bearing aluminum sulfate and chloride spring. The hotel does not publish a complete current analysis sheet, so this remains a secondary-source classification. Source: A hotel spring distinct from Sukayu's sources; the individual source name is not published on the current hotel text pages. | Source temperature: Not published on the current hotel pages. pH: Not published on the current hotel pages. | The hotel describes the public bath as source-flowing. Current text pages do not publish a full treatment breakdown. | Day-use bath. A high-spend option for visitors combining a proper lunch with a quiet hotel bath, sauna, cold plunge and free transport. It is not available for bath-only day visits: you need a qualifying lunch reservation, so budget at least ¥5,150 per person including bathing tax. |
