The spring water of the Oga Hot Spring contains salt compounds similar to that of seawater. After a bath, the salt compounds in the spring water prevent sweat from evaporating. Due to the heat-retaining properties of the spring water, it is known for its skin care effects and is also known as "Netsu-no-Yu". The hot springs at our hotel is from a "Free-Flowing Hot Spring Source". (However, minimal addition of water and heating is conducted according to the season and temperature.)

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.
