Top Kanto Swimming in 2026

See a different side of Tokyo as you leave behind the concrete jungle for a day of canyoneering amidst the lush landscape of the nearby Okutama area on this 4-hour excursion. Spend your trip repelling down into mossy-green canyons (some as high as 80 feet (25 meters)), cliff jumping and zooming down naturally-formed waterslides into crystal-clear pools. You’ll spend more than 80% of your day in the water and get to choose between two different courses, perfect for beginners and experienced canyoneering-lovers alike. This canyoneering half-day trip also includes a professional guide, round-trip transport from the train station, all equipment and tour videos and photos.
