Nakagawa Aquatic Park

The only aquarium in Tochigi prefecture.

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.

Nasu Area

The Nasu area, in the northeastern part of the prefecture, is famous for the imperial villa located there, and is one of Japan’s premier resort areas with its expansive highlands. The climate has allowed the development of a thriving dairy industry, and while there, you can visit a dairy farm that is open to tourists and offers delicious sweets made from milk, such as soft-serve ice cream and cheesecake. There are also many family-friendly facilities like Safari Park, amusement parks, and hot spring facilities like Shiobara Onsen.
