What is the Niyodo River?<\/h2>\r\n

\"\"<\/p>\r\n

Flowing across Ehime and Kochi Prefectures, the Niyodo River<\/strong> stretches for 124 kilometers with a basin of 1,560 square kilometers. On the Ehime side it is called the Omogo River<\/em>, but once it reaches Kochi, it becomes the Niyodo\u2014the name that travelers remember.<\/p>\r\n

The river has been designated a Class A River<\/em> by Japan\u2019s Ministry of Land, Infrastructure, Transport and Tourism, marking it as especially important for both national land conservation and the economy.<\/p>\r\n

It is also home to several dams, such as the impressive Odo Dam<\/strong> (the second largest in Shikoku), along with the Kae Dam<\/strong> and Ikadazu Dam<\/strong>, built for flood control and hydroelectric power generation. These facilities make the Niyodo one of the most utilized rivers in the region.<\/p>\r\n

Here are three key features that make the Niyodo River stand out.<\/p>\r\n

The Cleanest Water in Japan<\/strong><\/p>\r\n

In 2019, after a survey of 162 Class A rivers nationwide, the Niyodo River was awarded No.1 in water quality for the second consecutive year.<\/strong><\/p>\r\n

It was also recognized as one of Japan\u2019s 16 rivers with the very best water quality that year\u2014the only one in all of Shikoku to receive this distinction.<\/p>\r\n

A Paradise for Outdoor Leisure<\/strong><\/p>\r\n

The river\u2019s middle to lower reaches are abundant in water, creating an ideal setting for outdoor fun. Visitors can enjoy camping, fishing, canoeing, and more.<\/p>\r\n

In recent years, adventurous activities like rafting, stand-up paddleboarding (SUP), and shower climbing have also become popular, drawing nature lovers and thrill-seekers alike.<\/p>\r\n

The Magical \u201cGlowing Forest\u201d<\/strong><\/p>\r\n

In the midstream area rises Mt. Yokokura<\/strong>, known as the \u201cGlowing Forest.\u201d<\/em><\/p>\r\n

The forest owes its name to luminous mushrooms (Shiinotomoshitake<\/em>) and the countless fireflies that inhabit the area. Depending on the season and time, you can witness a breathtaking collaboration between crystal-clear waters and flickering natural lights.<\/p>\r\n

The Famous \u201cNiyodo Blue\u201d<\/h2>\r\n

Above all, the Niyodo River is celebrated for its extraordinary color: a mystical, pure shade of blue known as \u201cNiyodo Blue.\u201d<\/p>\r\n

The name was coined by nature photographer Nobuyuki Takahashi, who was captivated by its clarity and brilliance. Since then, travelers from all over the world have come seeking this remarkable sight.<\/p>\r\n

The reason behind the vivid blue is not completely proven, but leading theories include:<\/p>\r\n

\u30fbThe water temperature is low, making it difficult for algae to grow.
\r\n\u30fbThe hard surrounding rock produces little mud or sediment.
\r\n\u30fbThe current is swift, preventing impurities from building up.
\r\n\u30fbClearer water reflects more blue wavelengths of sunlight, making it appear more vivid.<\/p>\r\n

While the \u201cNiyodo Blue\u201d can be seen along most of the river, certain locations are especially famous for it:<\/p>\r\n


\r\n\u30fbNiko Falls (Niko-buchi)
\r\n<\/strong>\u30fbNakatsu Gorge
\r\n\u30fb<\/strong>Yasui Gorge<\/strong> (particularly Suisho-buchi and the Sab\u014d Dam)<\/p>\r\n

Because the color shifts depending on season, weather, and sunlight, no two visits are exactly the same\u2014an invitation to return again and again.<\/p>\r\n

Must-See Spots Along the Niyodo River<\/h2>\r\n

Here are seven destinations you won\u2019t want to miss.<\/p>\r\n

Nagoya Chinka Bridge(submersible bridges)<\/h3>\r\n

The longest of the six chinka bridges (submersible bridges) along the Niyodo, stretching 196 meters.<\/p>\r\n

When the water is shallow, you can see fish swimming beneath in the shimmering blue\u2014an image that has made the bridge especially popular on Instagram.<\/p>\r\n

It is also the closest submersible bridge to Kochi City and is still used as a daily crossing by local residents.<\/p>\r\n

(Chinka bridges are designed without railings; they function as regular bridges during low water but submerge beneath the surface when the river floods.)<\/p>\r\n

This waterfall basin in the upper reaches of the river is perhaps the most iconic view of Niyodo Blue.<\/p>\r\n

Once considered sacred\u2014the locals believed a great serpent god lived here\u2014it was avoided for generations. That changed after photographer Nobuyuki Takahashi captured its beauty, spreading its fame across social media.<\/p>\r\n

The most magical time to visit is around midday on a clear day, when sunlight pours directly into the basin, creating an otherworldly glow.<\/p>\r\n
