“Tamago no Yu” is a special hot spring that originates from a source discovered about 900 years ago by Hanko Takahashi. The water from this source is poured into the bath without any added water or heating, preserving its natural state and preventing oxidation. This method allows the hot spring minerals to directly benefit the skin, providing significant health effects. The temperature of the hot spring is a miraculous 43.5°C, gifted by the earth’s energy, creating an ideal bathing environment. With its flow-through system, the water is refreshed every three hours, maintaining a consistently clean state. This ensures a hygienic and fresh hot spring experience accessible to all ages.
