TheNagara River (長良川,Nagara-gawa) has its source in the city ofGujō,Gifu Prefecture, and its mouth in the city ofKuwana,Mie Prefecture,Japan. Along with theKiso River andIbi River, the Nagara River is one of theKiso Three Rivers of theNōbi Plain. Previously, the river was namedSunomata River (墨俣川Sunomata-gawa). With a length of 166 km (103 mi), it drains an area of 1,985 square kilometres (766 mi2) in theChūbu region and empties intoIse Bay. The government of Japan classifies it as a Class 1 river.
Also, famous for being a clear-flowing river, it has been named one of the "Three Clear-Flowing Rivers in Japan," along with theKakita River inShizuoka Prefecture and theShimanto River inKōchi Prefecture. In 1985, the middle section of the Nagara River was named to "Japan's 100 Famous Waters." It was included among Japan's top bathing areas in 1988 and again in 2001. The river is also a popular tourist destination because ofNagaragawa Onsen, a collection of natural hot springs (mostly in the city ofGifu) that are known for their high iron content.[1]
Downstream, the Nagara River converges and diverges with the Kiso andIbi rivers multiple times. Though the Nagara River is considered part of the Kiso River system, various construction projects over the years have kept the two rivers separate all the way to the mouth of the river.
Other construction projects had previously changed the flow of the river, too. Up until theShōwa period, two minor rivers diverged from the Nagara River in the heart of the city of Gifu, but construction in 1939 created the current path of the river through the system. As a result of this construction, about 160 ha (0.62 mi2) of land was recovered, upon which theGifu Memorial Center, schools, and other buildings were built.

Cormorant fishing is an ancient tradition in whichcormorants are used to catch various fish in lakes and rivers. Cormorant fishing takes place in two cities: Gifu, where it is called "Cormorant Fishing on the Nagara River,"[2] and Seki, where it is called "Oze Cormorant Fishing" (小瀬鵜飼Oze Ukai). Though eleven other places in Japan also host cormorant fishing, only the fishing masters on the Nagara River are Imperial Fishermen of the Household Agency.
