There hasn't been much development work done, and the nostalgic scenery remains. You might even be able to see salmon swimming upstream in the fall. First-timers can enjoy river rafting.The Naka River, which originates from the Nasu Mountain Range, has a total length of approximately 150 km. It is one of the clearest streams in the Kanto region, flowing through Tochigi and Ibaraki prefectures and flowing into the Pacific Ocean from Oarai. The Nakagawa River near Nasukarasuyama City is wide and meandering, creating an old-fashioned natural landscape. There is a lot of untouched nature here, and it is one of the few clear streams in the Kanto region. During the tour, we saw many plants, wild birds, and fish. You'll also be able to see the riverbanks used for shipping during the Edo period. Especially in the fall, when you can see the autumn leaves from the river and see many salmon swimming upstream, you will be able to spend a luxurious time with many moving scenes. Let's enjoy rafting at a leisurely pace while entrusting ourselves to the flow. We are a top-class guide and risk management company among outdoor companies in Tochigi Prefecture. Since opening in 2004, we are currently breaking the record for zero accident insurance coverage for rafting and kayaking projects. Additionally, as an option, we offer a special ayu set meal from Hinokiya, one of the largest Ochiishi sightseeing restaurants in the Naka River. Let's enjoy the deliciousness of Naka River.
