First-Ever Cherry Blossom Display at THERMAL SPA S.WAVE Outdoor Terrace
"THERMAL SPA S.WAVE" captivates visitors with its sense of openness where the sea and sky seem to merge. During the event period, the outdoor terrace will feature cherry blossom artificial flower decorations for the first time, recreating the texture and branches of real trees with remarkable authenticity.
The cherry blossom art's vibrant colors blend with the ever-changing scenery to create a fantastical atmosphere. Guests can enjoy a unique hanami experience by viewing the cherry blossom art from the infinity pool or savoring limited-edition sweets and drinks on the outdoor terrace.
Cherry Blossom Art Space Filled with Fragrance
At "S.DINING BAR" located in the center of the lobby, the cherry blossom artificial flower art is complemented by cherry blossom aroma scent production. The cherry blossom display overlaps with the garden and ocean views visible through the large windows, transforming the hotel interior into a photo-worthy space that conveys the arrival of spring. The subtle cherry blossom fragrance invites guests into an extraordinary world from the moment they arrive.
