FacilitySpringSource dataSupplyBath type
Kin no Yu (Gold Bath)Iron- and sodium-chloride spring; strongly saline. Source: Tenjin and Uwanari sources.Source temperature: About 99.4–100.5°C.
pH: Not published in the current material reviewed.
Source water is heated and disinfected. The facility drains and cleans the baths daily; this is not an untreated, no-circulation source-flowing bath.Day-use bath. Arima's best-known gold-coloured spring is a straightforward choice for a short public-bath visit. Its strongly saline water is hot at the source, and the facility heats, disinfects and manages the bath water rather than offering untreated source water.
Gin no Yu (Silver Bath)Silver-spring bathing system using mixed spring water; the carbonated source is listed at 18.3°C. Source: A blend of carbonated and radium-bearing spring sources.Source temperature: 18.3°C for the carbonated source; a separate temperature for the radium-bearing source was not confirmed.
pH: Not published in the current material reviewed.
The mixed water is heated and partly circulated. Water may be added and chlorine disinfection is used. The baths are drained and cleaned daily.Day-use bath. A quieter-feeling counterpart to Kin no Yu, with a mixed silver-spring supply and a more modest public-bath setup. The spring is heated and partly circulated, so the source description should not be mistaken for untreated water in the tubs.
