  • Blissful Me Time

    A relaxing, tranquil Accommodation for adults. Watch the ever-changing sky, sea, and forest, and the sparkling stars; soak in the Onsen whenever you like; and enjoy high-quality meals... Above all, the staff’s hospitality is outstanding. During my stay, they never once asked for my name or Room number, and they even adjusted the end time of dinner to fit my spa Reservation. Thanks to their seamless communication and thoughtful care, I felt completely at ease throughout my stay. I will be back again. Thank you very much.

    I was able to relax on the sofa while enjoying the view of Oshima from the Room.There was a massage chair in the Room, which was great for easing my swollen legs after being stuck in traffic.Oshima could also be seen from the open-air bath in the Room, and since it was a private open-air bath attached to the Room,I was able to soak in the Onsen at my leisure.Dinner and breakfast were delicious.The simmered kinmedai (splendid alfonsino) was especially well-seasoned and very enjoyable.I will stay again, and I look forward to visiting you.

To achieve the best natural flow of the Onsen, it is essential to have the technology to account for factors such as the day's weather, temperature, and the condition of the Onsen. While most properties have abandoned the mastery of this technique in favor of machine management, our establishment has remained committed to the traditional practice of "Yumori" — Onsen artisans who manage the temperature and quality of the Onsen — since the founding of our main branch over a century ago. Maintaining the natural spring water, which is approximately 100°C, at the perfect bathing temperature is no easy task. With daily changes in weather and temperature, continuing this process throughout the year requires great skill and dedication. Human skin can perceive even a 1°C difference from the ideal 42°C as "too hot" or "too cold." Driven by the sincere desire to provide our guests with an Onsen experience at the perfect temperature, our Yumori artisans measure and adjust the temperature daily using their wrists. The existence of "Yumori" is a rare and unique tradition, even across Japan. Please enjoy this lost art of traditional Japanese craftsmanship.
