Located in the eastern area of Tochigi， this Onsen snuggles into a bend of the Naka River. The simple alkaline hot spring water promotes smooth skin， for which the Onsen is known as the “hot spring of beauty”. Most of the hot spring baths in the area face west， leading to another nickname of “the sunset Onsen-kyo” thanks to the great sunset views. You can also have a splendid view of mountains with wisps of white smoke.

From the Nakagawa River， the best clear stream in the Kanto area， to rivers in the world (Amazon River)， then to the Longing Sea (fish in coral reefs)， are introduced in approx. 60 water tanks， in various sizes from small to large. The attraction of the river， which the sea does not have， is definitely the sunlight shining deep through the water. A large amount of sunlight is taken in at the aquatic park， recreating the scenic riverbed. As natural light shines through the water， the fish actively swim in the aquarium， which is an attractive part of this park which cannot be experienced at a marine aquarium. There are many interactive areas as well， including touching tanks where visitors can encounter crayfish and starfish directly."
