[Shimanto City, Kochi Prefecture] “Japan’s Last Pristine River, the Shimanto River” — a river where people live alongside the water and that sustains a culturally rich landscape
☞ What is the Shimanto River?
……………………………………………
The Shimanto River originates on Mt. Irizuyama in Tsuno Town, Kochi Prefecture (elevation 1,336 m). It runs 196 km in total, with 35 main tributaries and 319 tributary streams overall. The river meanders through the southwestern part of Kochi Prefecture—including Yusuhara, Nakatosa, Shimanto Town, and Shimanto City—flowing without steep drops before emptying into the Pacific Ocean at Shimanto City Shimoda.

☞ Where the name “Japan’s Last Pristine River” comes from
……………………………………………
The Shimanto River, where residents still live close to the water, gained the symbolic label “Japan’s Last Pristine River” after a 1983 television broadcast. That description created a brand image of a clear, life-filled river running from its source to the sea.
……………………………………………
☞ What the Shimanto River provides.
……………………………………………
Nurturing abundant life, the Shimanto River and its wide estuarine areas host around 200 species of aquatic life. Even today, some fishers sustain their livelihoods using traditional methods such as late-season sweetfish (ayu) fishing, fire-fishing, long-armed shrimp fishing, goby fishing, and green seaweed harvesting. These practices preserve deep ties between people and the river and a living culture of work.

☞ Activities on the Shimanto River.
……………………………………………
On the Shimanto River you can enjoy canoeing, stand-up paddleboarding, cycling, stream-walking, raft trips, sightseeing boats, camping, and many other year-round experiences.
……………………………………………
☞ The river’s tempestuous side.
……………………………………………
The Shimanto River is also famous as a wild river prone to rises in water level, flooding, and typhoons, making it susceptible to water damage throughout the year. Against this backdrop, people living along the basin have adapted their lives and landscape to nature, for example with low, railing-free bridges called chinkabashi that submerge during high water. These bridges, together with human activity, create a distinctive regional scenery.

☞ Selected by the Environment Agency as one of Japan’s 100 Exquisite Waters and the 100 Exquisite Waters of the Heisei era.
……………………………………………
In July 1985, the Shimanto River was chosen as one of Japan’s 100 Exquisite Waters because of its excellent water environment and active local conservation efforts.
Later, in June 2008, the Kuroson River, a tributary of the Shimanto, was recognized as one of the 100 Exquisite Waters of the Heisei era in recognition of environmental conservation activities and local community initiatives.
……………………………………………
☞ The exceptionally clear Kuroson River among the tributaries.
……………………………………………
The Kuroson River, selected for the Heisei-era 100 Exquisite Waters, is the clearest and most beautiful tributary of the Shimanto River. The area also preserves legends and stories such as Kuroson Shrine and Okiku Falls, and in autumn the foliage colors the landscape vividly.

☞ Designated as an Important Cultural Landscape by the Ministry of Education, Culture, Sports, Science and Technology.
……………………………………………
In February 2009, the unique landscapes formed by people’s lives and activities in the Shimanto River basin were designated an Important Cultural Landscape. This is the first time such designation covered five municipalities in the basin—Tsuno, Yusuhara, Nakatosa, Shimanto Town, and Shimanto City—drawing significant attention.
※ An Important Cultural Landscape is a landscape formed by people’s lives or livelihoods and the local natural environment, and is indispensable for understanding the lives or occupations of our nation’s people (from the Cultural Properties Protection Law, Article 2, Paragraph 1, Item 5).
