◆ 100% natural, untouched free-flowing hot spring water ◆
The hot spring at Ryokan Kounoyu comes from private on-site hot spring sources.
In general, a hot spring is described as free-flowing when fresh hot spring water continuously flows into the bath and overflows naturally, rather than being circulated through a filtration system.
Ryokan Kounoyu's abundant hot spring water supply is sufficient to provide even its large public baths with 100% natural free-flowing hot spring water.
In addition, no water is added, and the hot spring water is never heated, disinfected with chlorine, or circulated through a filtration system. As a result, guests can enjoy the exceptional quality of the hot spring in its pure, natural state.
The spring quality is classified as "Sodium, Calcium - Hydrogen carbonate / Sulfate / Chloride springs (Hypotonic, Neutral, High temperature spring)".
Although the water is clear and colorless when it emerges from the source, it gradually develops a faint yellowish, slightly cloudy appearance as iron ions in the hot spring water react with oxygen in the air.
The water also contains a small amount of naturally dissolved carbon dioxide. Its mineral composition helps remove excess oil and soften dead skin cells, much like a gentle cleanser, leaving your skin feeling smooth and refreshed after bathing.
This "Hypotonic, Neutral, High temperature spring" is gentle on the skin, making it suitable for everyone—from babies to older adults, including people with sensitive skin.
Every guest room at Ryokan Kounoyu features either a private open-air bath or a semi-open-air bath. All are filled with 100% natural free-flowing hot spring water of exceptional quality. Each bath has its own distinctive design, allowing you to enjoy a private and relaxing bathing experience surrounded by nature.
