Kiso Three Rivers

The Kiso Three Rivers (木曽三川, Kiso Sansen) are the three major rivers that make up the alluvial plain area of the Nōbi Plain of Japan. The three rivers are the Kiso River, the Ibi River and the Nagara River. Given their location, they are sometimes referred to as the Nōbi Three Rivers (濃尾三川 Nōbi Sansen).
