Blow Away the Heat with Water Splashes! The Complete Guide to 2026 "Kanto Rafting"

With more days exceeding 30 degrees Celsius lately, rafting is drawing significant attention as an activity to enjoy both coolness and thrills. Rafting is a river sport where participants board a large rubber boat and work together to navigate rapids. Its greatest appeal lies in experiencing the natural roller-coaster-like exhilaration, the cool breeze blowing across the river, and the beautiful canyon scenery with your entire body.

Especially during the upcoming season when temperatures rise, descending the river while being splashed by cold water instantly clears away daily stress. Here, we provide a thorough explanation of the "Top 3 Kanto Rafting Spots," along with necessary preparations and safety tips, so even beginners can enjoy it with peace of mind.

Basic Knowledge to Enjoy Rafting 120%

【Necessary Preparations and Belongings】

Many tour companies rent safety equipment such as wetsuits, helmets, and life jackets for free. The essential items that participants should prepare are as follows:

・Swimwear: To be worn under the wetsuit.

・Towel & Change of Clothes: It is common to take a shower and change clothes after the tour.

・Shoes that can get wet: Sports sandals with heel straps or sneakers (rentals are often available for about 300 yen).

【Rafting on Days Exceeding 30°C】

Nicely warming weather makes playing in the river—such as jumping into the water from the boat in gentle currents or floating along—the ultimate relaxation. However, because the sunlight on the water is strong, UV protection such as wearing a rash guard and sunscreen is essential.

【Safety Precautions】

・Follow the Guide's Instructions: "Paddle!" or "Sit inside the boat!"—the guide's cues are the key to safety.

・Physical Condition: Avoid heavy drinking the night before and show up in top physical condition. Participating while intoxicated is strictly prohibited.

The Holy Land of Rapids: "Minakami Area" (Gunma Prefecture)

If you are looking for the most exciting experience in Kanto, "Minakami" ranks a solid first. The tours descending the upper Tone River, one of Japan's largest rivers, offer world-class rapids (white water), especially from spring to early summer when the water volume increases due to melting snow. The area features many bases with experienced guides, such as the long-established "Forest & Water," ensuring high safety. The sense of achievement after overcoming the rapids is an exceptional experience you can't get elsewhere.

Resource of Natural Monuments: "Nagatoro Area" (Saitama Prefecture)

Viewing the "Iwadatami" rock formations, a designated national natural monument, from the river is a luxurious experience offered by "Nagatoro." The area has a good balance of rapid and gentle points, and since many tours welcome children from the first grade of elementary school, it is ideal for families and rafting beginners. Access from the station is excellent, and enjoying the famous shaved ice after the tour is a classic Nagatoro treat. Bases with well-equipped facilities like "Nature Navigator" are popular.

Oasis Right Outside the City: "Okutama Area" (Tokyo)

It is surprising to find such rich nature left in the upper reaches of the Tama River, making visitors ask, "Is this really Tokyo?" The greatest appeal is the convenience of a 90-minute train ride from Shinjuku. You can enjoy rafting and diving in the river while admiring the beautiful scenery of the Mitake Valley. Many facilities, such as "Okutama Crusoe," are equipped with powder rooms and changing rooms, making them highly popular among women and student groups.
