Five-star intensity! Control is up to you! Hydrospeed is the ultimate river sport, where you put fins on your feet, climb into a custom-made one-person rubber boat, and let yourself go with the current of the river. Not only can you enjoy the fun of controlling it yourself, but you can also feel the power of being just above the water's surface and a direct sense of oneness with the river with your body. It is often described as the river version of bodyboarding, and the best part is surfing the river's waves and reading the current to decide your own course. Easy access from the Kanto region (^o^)丿 Free transfers from [Joetsu Shinkansen Jomo-Kogen Station], [Joetsu Line Minakami Station], and hotels in Minakami Town! You can enjoy it on a day trip from the Kanto region, so why not spend your free time in Minakami Town, Gunma Prefecture, enjoying nature and being active (^o^)丿
Board the special body board "Hydro Speed" made for the river alone and go down the rapids of the Tone River while lying down. The line of sight on the surface of the water doubles the power! There are instructions from the guide before the start, so you can enjoy the technical torrent course and the big dip with your own power! !! It is a popular tour for repeaters because it is hard and has a great sense of accomplishment and exhilaration!
Kappa CLUB was introduced as a tour for the first time in Japan in 2000 with this hydro speed that originated in France. Kappa CLUB guides were involved in the development of a hydro speed boat that takes into consideration the physique of the Japanese and the characteristics of the river through trial and error. The exclusive wet suit that was imported from the original France has now adopted an extra-thick model with a thickness of 8 mm that was custom-made in Japan. Protects the body that is constantly immersed in water from the cold and obstacles.
More than half of the Hydrospeed participants are new to women. If you are not confident in your physical strength or cannot swim, don't worry! In addition to the buoyancy of the wetsuit itself, you will also wear a life jacket so you will not have to worry about drowning. If you don't break your heart, strong guides will run side by side and take you to the goal! Courses are set according to the level and physical strength of the customer on the day, so please feel free to join us.
