Originating in France, canyoning is an activity in which participants traverse canyons using a range of techniques including sliding down natural chutes, jumping into waterfalls and descending gorges by rope. Nametoko Gorge is located at Mt. Onigajo in the southwest of Shikoku, a scenic place on one of the tributaries of the Shimanto River. The gorge is renowned as one of the best canyoning spots in Japan with lots of slides and uninterrupted smooth rocks of granite. There is no more thrilling experience than sliding down superb scenery such as Yukiwa Falls, designated as one of the best 100 waterfalls in Japan. Friendly instructors are on hand to offer advice so that even beginners can enjoy this natural adventure sport.
