Totonou in a panoramic grand public bath overlooking the Pacific Ocean and an auto löyly sauna
"Hotel Aoshima Cinqmale" is a scenic hotel located in Aoshima, Miyazaki City, Miyazaki Prefecture. Right in front of it stretch the Pacific Ocean and the unique rock formations known as the "Devil's Washboard," and the grand public bath on the 3rd floor offers sweeping views of this magnificent scenery. The hot spring is a naturally sourced sodium bicarbonate spring from the hotel’s own source, with a smooth, silky texture. The sauna, renovated in 2026, is equipped with auto löyly, allowing you to enjoy an authentic sweat session while surrounded by the scent of hinoki cypress. Outdoor bathing on the veranda, where you can feel the sea breeze, is also exceptional.
Luxurious use of a naturally self-springing hot spring from underground. This silky sodium bicarbonate spring is known as a beauty bath and helps leave the skin smooth and refined. While gazing at the Pacific Ocean panorama through the large windows of the grand public bath, you can fully enjoy a soothing and restorative time.
A state-of-the-art sauna renovated in 2026. The room is filled with the scent of hinoki cypress, and auto löyly has been introduced to provide powerful heat and a pleasant level of humidity that encourages a comfortable sweat. You can also enjoy a spectacular view of the Pacific Ocean from the windows, spending a blissful sauna session in a spacious, open setting.
A cold plunge bath located right next to the sauna. The crisp, cold water gently envelops your heated body and provides a refreshing cool-down. After the cold plunge, head to the panoramic veranda for an open-air bath in the sea breeze. Listening to the sound of the waves, you can experience the ultimate relaxation.
