01 Receptionh

As a reminder for customers taking part in hydrospeed tours, please go to the washroom before changing clothes and receiving equipments. After changing clothes, The Hydrospeed Guide will give instructions, Please wait while the guides are preparing your body board. Get the equipment you need for Hydrospeed by following the instructions in the guide. All equipment is included in the tour fee at the Big Wave Oume branch. Get on the bus and leave. Hydrospeed Guide will carry out the tour safely.

02 Changing clothes / equipment

Hydrospeed is a single-seated boat that is finned by its own power and is different from rafting boats, canoeing, kayaking, etc. There's a handle on the tip of the boat that holds it with both hands, so clasp it. Not only to leave your body to the flow of the river, but I also use the propulsive force of the fins. The experience of feeling and operating the torrent all over the body is a feeling of exhilaration and thrill. It is a great outdoor sport for anyone who wants to enjoy hydrospeed, or who just wants to enjoy the river. First of all, you will receive a safety explanation and a lecture on operation, so even beginners can participate safely.

03 Safety Explanation

Ride your body board alone. You can also enjoy technical torrent courses and large holes. The most difficult thing for beginners is to put the board upside down with waves. Practice repeatedly until you can do it without problems so that you won't turn left or right or stop on a stone. It is good to learn how to operate the board. It is a departure from the upstream of the Tamagawa River aiming for the torrential current.

04 Start!!

There is also a point where you can feel at ease. You can also spend a relaxing time entrusting yourself to the beautiful flow of the upper part of Tama River. Listen to the sound of the Okutama Tamagawa river's stream, the birds' voices, and the winds of the Tamagawa river's surface.

05 Relax time!

Can I get over the plain? Basically, guides will guide you to the points where there is a hard flow. Of course, we will support the guide firmly, so please try to fight the torrent of Tama River. The sense of accomplishment is the highest tide when cleared.

06 Torrent

Hydrospeed has a great sense of accomplishment and a sense of exhilaration. I would like to do it again once, it is a popular hydro speed tour offered by Big Wave. The last photo was taken with everyone. As Okutama Base screens photos and videos taken during the tour, please relax and see. You can also download for free from the QR code you received at the reception. Please be aware that in rare cases the camera may be damaged by flooding or the data may disappear.
