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."

A place steeped in Tokugawa Mitsukuni’s legend, worship traditions, and famous autumn foliage Located in Nakagawa Town, the Gozeniwa Stone is a designated natural monument of Tochigi Prefecture. It is said to have been visited by Tokugawa Mitsukuni (Mito Komon), giving the stone its name. Standing 30 meters high and 70 meters wide, this massive boulder resembles a seated Kannon statue, earning it the name “Great Kannon Rock.” Since ancient times, it has been revered as a place of worship for safe childbirth and family well-being. The area surrounding Gozeniwa Stone is home to a clear mountain stream, selected as one of the “Heisei 100 Best Waters.” With refreshing scenery that changes across the four seasons, nearby Mt. Nasu and the riverbanks of Shikanoyu provide relaxing walking trails. In autumn, from late October to mid-November, the area transforms into one of the region’s most popular spots for vibrant autumn leaves. The harmony of the red foliage, pristine stream, and majestic rock creates a tranquil yet impressive sight, making it one of the highlights of Nakagawa Town’s natural beauty.
