You are greeted by walls painted in a deep "midnight blue," reminiscent of the dead of night, with the spectacular scenery of Atami stretching out beyond. Designed with the "Moon Road"—the path of moonlight on the water—as its theme, this is a space where the colors of the walls and ceiling accentuate the mystical moonlight, making the Moon Road even more prominent.

The semi-open-air bath features a basin that juts outward, allowing you to enjoy the spectacular view with the sensation of floating in the sea. The midnight blue walls further highlight the changing scenery of Atami, from the morning glow to the evening lights, allowing you to fully immerse yourself in its beauty.

The entrance expresses the Moon Road through lighting and mosaic art. Furthermore, the changing room is furnished with mirrors depicting the phases of the moon. You can fully enjoy the theme of the Moon Road and the lunar cycle not only in the bath itself but throughout the entire space, from the entrance to the changing rooms.
