Shirasuna Open-Air Bath

Shirasuna (露天風呂しらすな, Rotenburo Shirasuna) offers a unique and memorable onsen experience, featuring breathtaking ocean views on the beach. This spacious seaside bath can accommodate up to 100 people, creating a lively yet relaxing atmosphere that combines the soothing warmth of the hot spring with the cool, invigorating sea breeze. The bath’s open-air design allows guests to fully immerse themselves in the natural surroundings, making it a refreshing and picturesque setting that sets it apart from traditional onsens.

Unlike typical onsens, Shirasuna invites guests to wear bathing suits due to its public exposure, making it a more casual and inclusive experience. This makes it an ideal spot for groups, couples, and families looking to enjoy a fun, relaxed hot spring experience without the usual strict onsen etiquette. Whether you're soaking in the warm waters while gazing out at the ocean or enjoying the lively atmosphere with loved ones, Shirasuna provides a one-of-a-kind opportunity to enjoy both relaxation and adventure by the sea.
