Asahi-no-Yu is a hot spring fed by a 100% natural water spring. Their baths use a special chemical composition of sodium, alkaline and sulfur, giving them excellent medicinal as well as relaxation properties that have made them well-loved by the locals. They have two indoor baths overflowing with warm spring water that reach almost 1m in depth, as well as an open-air bath.  We think you’ll find dipping between the two quite charming!
