Niyodo River
One of the most beautiful rivers in Japan, known for its stunning "Niyodo Blue" waters.
Originating from Mt. Ishizuchi, the highest peak in western Japan, the Niyodo River spans approximately 124 km across Ehime and Kochi Prefectures, making it one of Shikoku’s three major rivers. Frequently recognized as the cleanest river in Japan, it is celebrated for its unparalleled clarity and vibrant blue color, known as "Niyodo Blue," drawing numerous tourists eager to witness its beauty.
The best spots to see the "Niyodo Blue" are often in the upper reaches of the river, with top recommendations being “Niko Pool,” “Yasui Valley,” and “Nakatsu Valley.” The appearance of the river’s blue hues can vary by season and weather, so it’s wise to check conditions beforehand.
Visitors can enjoy various river activities such as SUP (Stand-Up Paddleboarding) experiences with crystal kayaks, zip-lining over Iwayagawa Valley, and guided tours. Barbecue by the riverside and sauna experiences are also available. Yokogura Mountain, known for glowing mushrooms and countless fireflies, as well as submersible bridges, erosion control dams, and waterfalls during high water levels, add to the river's many attractions.
