Supersento located across the bridge from Nagasaki Airport-it’s walkable. Typical supersento style with a quality hot spring. Shuttles to the airport and airport parking available. Family baths also available. Water has a dry, powdery feel to it and is very salty to the taste. It was so salty it made my face sing a little. Great selection of jet baths. Rare, cold sauna which would be awesome in the hot Kyushu summer.
