| Facility | Spring | Source data | Supply | Bath type |
|---|---|---|---|---|
| Sabako-yu Public Bath | Alkaline, hypotonic spring, according to an analysis from February 2005 cited by the Iizaka Onsen Tourism Association. | Source temperature: 51.0°C at the source/distribution tank; not the bath temperature. pH: Not published. | Current public-bath pages list source and distribution-tank details but do not provide a complete pool-by-pool treatment table for dilution, heating, circulation and disinfection. | Day-use bath. The first bath to consider if you want Iizaka's best-known historic public bath and only plan to visit one. If you prefer a choice of water temperatures, start with Hakoyu instead. Sabako-yu does not provide free shampoo or soap. |
| Hakoyu Public Bath | Alkaline, hypotonic spring, according to an analysis from December 2010 cited by the Iizaka Onsen Tourism Association. | Source temperature: 48.8°C at the source/distribution tank. pH: Not published. | Fukushima City's current page identifies a source-flowing hot pool and a warmer-adjusted pool. The adjustment method and complete circulation/disinfection details are not published. | Day-use bath. A dependable first Iizaka bath if you are new to the area, travelling with family or prefer a choice between hotter and cooler water. It is closed on Tuesdays, except when a public holiday changes the schedule. |
| Dosen-no-Yu Public Bath | Simple spring, according to a February 2005 analysis cited by the Iizaka Onsen Tourism Association. | Source temperature: 60.0°C at the source/distribution tank; not a measured pool temperature. pH: Not published. | Current shared-bath listings do not provide full pool-by-pool details on dilution, heating, circulation or disinfection. | Day-use bath. A practical choice if you are following the B-group bath pass and want a short walk from Iizaka Onsen Station. It is open most days, but closes on Fridays and has no dedicated parking. |
