Hyogo Kobe City
An iki stove heated to over 100 degrees and a single cold plunge bath at around single-digit water temperatures
A sauna facility inside Centurion Hotel & Spa Vintage Kobe in Kobe, Hyogo Prefecture. The men's bath features a high-temperature sauna with a giant iki stove and a single cold plunge bath at around single-digit water temperatures, among the coldest in Kansai, and authentic aufguss sessions are held every day. The women's bath is equipped with a skin-friendly steam sauna and a low-temperature carbonated bath, offering an exquisite relaxation space where you can forget the hustle and bustle of the city.
A spacious indoor bath in the men's bathing area. It comes with bubble and jet functions, gently easing full-body fatigue and stiffness through the massaging effects of fine bubbles and water currents. It is ideal for warming up before the sauna or finishing off a bath, allowing you to relax in soothing warmth.
A mildly warm carbonated bath installed in the women's bathing area, close to body temperature. The fine carbon dioxide dissolved in the water gently envelops the skin and slowly warms the body from the core. Because it is not too hot, you can bathe for a long time, and when used together with the steam sauna, it is expected to provide even greater relaxation and beauty benefits.
A full-fledged sauna room with a calm atmosphere, home to a giant Metos-made iki stove. The set temperature is extremely high, and the regular auto-löyly allows you to experience hard, intense waves of heat. Almost every day, authentic aufguss sessions are also held by skilled staff, delivering an overwhelming sweating experience that even sauna enthusiasts will appreciate.
A single cold plunge bath with water temperatures in the single digits, boasting some of the coldest water in Kansai. Body heat built up in the high-temperature sauna is instantly tightened by the sharp cold water. The intense cool-down brought on by the dramatic temperature difference is what attracts so many sauna lovers. An ideal setting for those seeking a deeply totonou experience.

Most of what we surveyed never even made it onto this site. This book is a further cut from what did. Our editor bathed in every onsen and sauna in it, and wrote only what they confirmed on the ground.
