Niyodogawa, town in Agawa district, Kōchi prefecture, Japan
Niyodogawa is a small town in Agawa District of Kōchi Prefecture, positioned along the upper Niyodo River among rocky gorges and lush green mountains. The quiet streets pass traditional houses surrounded by trees, while the river flows through the landscape with its distinctive bright blue water known as Niyodo Blue.
The area was historically part of Tosa Province, ruled by the Yamauchi family during the Edo period, when the local economy centered on farming, forestry, and mining. In 2005, Niyodogawa was formed from the merger of three smaller communities to sustain local government as the population declined over time.
The town celebrates the Akiba Matsuri festival in February, where residents wear colorful costumes and participate in processions to a local shrine. The tradition involves tossing wooden poles decorated with feathers from Onagadori, special roosters native to the area, reflecting how locals maintain and pass down historical practices.
The town has no direct train service, with the nearest station at Nishi-Sakawa a short drive away. Visitors should arrange car rentals or use buses to reach the gorges, waterfalls, and other natural spots in the area.
Niyodo Adventure offers canyoning and pack rafting activities where visitors jump from cliff faces into clear river water and slide down rocky slopes. These experiences provide direct access to the untouched wilderness that surrounds the area and appeal to those seeking hands-on nature exploration.
