Yuzaki, Shirahama, Wakayama Prefecture
Muro-no-Yu
A low-cost way to compare two distinct Shirahama springs in one bathhouse. The draw is the water itself rather than a scenic setting or a large range of facilities.

Bathing indications
Shirahama Town lists general bathing indications separately for the two springs. These are facility reference details, not a treatment guarantee.
The 74.0°C and 78.0°C figures are source temperatures, not fixed bath temperatures. The town and supplier use different wording for Miyuki spring's classification; both descriptions are retained rather than combined into a new analysis.
How to read a bath profile
Spring-source temperature and actual bathing temperature are kept separate. Each score is shown independently for comparison rather than collapsed into one overall score.
