Bathing in a radon hot spring boosts health!

At U-TOPIA fresh, safe radon gas is always delivered straight to our natural hot spring at just the right, constant concentration. Enjoy a relaxing soak in a radon hot spring any time around the clock!
Our comfortably warm (39.5 degrees C) spring water ensures that sweating begins at 3-5 minutes, reaching profuse levels at 10-15 minutes.
The recommended guideline is three baths daily, with each session of about 15 minutes duration.
(As you would expect, even at a higher frequency than this there is still no risk.)
In the 500 years since the Age of Civil Wars, Japanese have prized radon hot springs for promoting good health and beauty – and also for their anti-aging properties.
