The Hot Spring Source that Changes Colour with the Seasons

The Hot Spring Source that Changes Colour with the Seasons

The hot spring water used at our hotel is drawn from a natural hot spring source located around 500m away. At natural emerging hot spring source locations with measuring containers, the hot spring water source is very shallow - located around 10-15m underground. Due to this fact, the spring water is easily influenced by nature; hence the subtle change in hue with the seasons.

Day trip bath is also available.
