Celebrating its 70th anniversary, this Property offers a historic retreat for therapeutic stays. Tsubaki Onsen is a renowned hot spring with many therapeutic visitors, featuring soft, smooth waters with a pH of 9.9, known for its skin-beautifying properties. The mild, salt-free waters are safe even for babies, those with atopic dermatitis, or sensitive skin! Handrails are also installed in the bath area for added safety. The daily changing bath features not only medicinal herbs but also seasonal ingredients believed to benefit the skin, such as yuzu citrus, persimmon leaves, and seasonal flowers. The daily changing bath uses the natural spring water (31°C). While some may find it lukewarm, alternating between this and the heated bath (main bath) significantly enhances the Onsen's effects. Enjoy the therapeutic benefits of the Onsen in the large bathhouse, located 60 meters above sea level with a stunning view of the ocean. The ingredients used in our cuisine are carefully selected for safety and quality. Vegetables, rice, and miso are lovingly cultivated by local contract farmers. Fresh seafood is sourced from Tsubaki Fishing Port and nearby waters, ensuring the freshest catch. Each dish, from appetizers to the main course, is handcrafted by our skilled chefs. Our popular seafood kamameshi (rice pot dish) is highly recommended! Packed with the rich flavors of scallops and conger eel, it’s served hot and fluffy. Just a 15-minute drive from Shirahama Airport and Adventure World! Relax at our Property, where a professional roaster crafts delicious original coffee for you to enjoy.
