HistoryAs with all of Kōchi Prefecture, the area of Niyodogawa was part of ancient Tosa Province. During the Edo period, the area was part of the holdings of Tosa Domain ruled by the Yamauchi clan from their seat at Kōchi Castle. Following the Meiji restoration, the village of Ikegawa was established within Agawa District, Kōchi with the creation of the modern municipalities system on October 1, 1889. Ikegawa was raised to town status on April 1, 1913. On August 1, 2005, the town of Ikegawa and the village of Agawa, both from Agawa District, and the village of Niyodo, from Takaoka District were merged to form the town of Niyodogawa.

HighwaysLocal attractionsThe most popular festival held in Niyodogawa is the Akiba Matsuri, held annually on February 11. A day long procession up a hillside to the Akiba Jinja, it features elaborate costumes, a highly choreographed march and focuses on the tossing of long wooden poles topped with the tail feathers of Onagadori, the famous long tailed roosters of Kōchi Prefecture. Often designated as one of the three major festivals in the Kōchi festival calendar, it is the one occasion where many former residents of the town return to participate, particularly important for a small town ravaged by depopulation. Niyodogawa has two popular nature spots, Nakatsu Gorge and Yasui Valley. Nakatsu Gorge has a walking path to Uryu Falls. It has more dramatic views of the rock walls that make up the gorge. It has also become a spot for canyoning. There is a public hot bath at a small hotel called Yunomori. Yasui Valley has more waterfalls to explore. It also has some cottages to rent. Tourists come to Yasui Valley to see "Niyodo Blue," an iridescent blue color that is best observed when the sun hits the river at a low angle. Another spot to see "Niyodo Blue" is at Nikobuchi Falls in neighboring Ino Town. References
