Next door to adex inn, adex base offers a Back of House tour that reveals what goes on behind the scenes of the hot springs, as well as a hike where you can learn about Hell Valley and Shikotsu-Toya National Park. Simply soaking is only half the experience. Since you’ve come all the way to Noboribetsu, why not discover the secrets of its hot springs? A soak after a hike, with your body pleasantly tired, is something special.

Hot spring hopping at our group ryokan’s large baths
Guests staying at adex inn can use the large public baths at Daiichi Takimotokan as many times as they like during their stay. These baths offer a different atmosphere from the adex inn hot spring. They are also free-flowing from the source, and boast five different spring types: sulfur, sodium chloride, sodium bicarbonate, acidic iron (green vitriol), and sodium sulfate springs! Enjoy the many tubs, open-air baths, and sauna to the fullest. This is a special perk for adex inn guests, made possible because we are part of a group of hotels.

Free-Flowing “Yunohana” Hot Spring Experience
In this cozy bathhouse, the rich sulfur spring water flows straight from the source without passing through a filter, making it a bath you won’t forget once you try it. Many guests return again and again, drawn by the yunohana (mineral deposits) that settle at the bottom of the tub. Enjoy a hot spring experience that is different from Daiichi Takimotokan.
"Yunohana" are mineral deposits that form naturally in hot spring water. As the hot water rises to the surface and meets the air, it cools quickly and the minerals solidify, creating what is essentially a “natural bath salt.”:
