When you walk through the entrance of Karatsu Seaside Resort, you’re likely to be swept away into dreams of faraway lands. The design boasts Parthenon-like white pillars and views of a turquoise ocean, which calls to mind the Aegean Sea. The resort’s latest facilities, open to all guests, include massage salons, aestheticians, indoor and outdoor pools, and a gym for the ultimate wellness vacation. Relax in the open-air hot spring or sauna. Perhaps the best feature is the open-air thermal pool on the rooftop. It’s mixed gender and bathers (who are required to wear swimsuits) can enjoy views over the coast and the pine grove.
