Water and bathing details for Kirishima Onsen

Facility-level figures; blank town-wide averages are not inferred.

Named facility records for Kirishima Onsen. Figures marked “Not published” are not treated as town-wide averages.

Facility	Spring	Source data	Supply	Bath type
Myoken Ishiharaso	Sodium-calcium-magnesium bicarbonate spring. Source: The ryokan's Amaten-den spring system, supplied by seven in-house springs.	Source temperature: About 56°C at the self-flowing source; this is not a bathing-pool temperature. pH: Not published in the current material summarized here.	The ryokan says it does not add water or heat the source before use. Its self-flowing water at about 56°C passes through a heat exchanger, with limited air contact, to reach around 42°C while retaining its mineral content. Seven springs supply different baths. The ryokan gives about 150 L/min as a design example of water filling a bath in an hour; this is not presented as the combined output of all seven springs. It also describes operation without dilution or chlorine disinfection.	Day-use bath. A useful benchmark for a first visit to Myoken if clear information about water treatment and a riverside setting matter most.
Myoken Onsen Nemu	Sodium-calcium-magnesium bicarbonate spring. Source: Nemu's self-flowing spring at Myoken Onsen.	Source temperature: 53°C at the source; not a fixed bathing-pool temperature. pH: Not published in the current material summarized here.	The facility says it does not add water or circulate the spring. A heat-exchange system brings the self-flowing water to a comfortable temperature while limiting air contact; the operator describes it as 100% spring water. The current text pages do not fully specify disinfection conditions, so none are inferred.	Day-use bath. A strong all-round choice for day visitors to Myoken who want several baths, a practical price and a visit without bringing their own basics.
Orihashi Ryokan	Bicarbonate spring. Source: Orihashi Ryokan's self-flowing springs, including Kizu-yu.	Source temperature: 54°C, the facility-specific spring temperature listed by the Japan Onsen Association; not the fixed temperature of the day-use indoor baths. pH: Not published in the current material summarized here.	The ryokan explicitly describes its outdoor bath as 100% source-flowing, and Kizu-yu as a naturally lukewarm spring unique to the property. The ordinary day-use baths are Kizu-yu and Take-no-yu; their water addition, heating, circulation and disinfection are not fully documented pool by pool. The outdoor bath's source-flowing description is not extended to every indoor bath.	Day-use bath. A good fit for visitors drawn to Myoken's historic bath culture, a naturally lukewarm spring and a ¥500 soak, rather than a large open-air facility.
