Doki RiverGeographyThe source of the Doki River is located on Mt. Ryuo in the Sanuki Mountains. It flows north along Japan National Route 438 through the Marugame Plain until it reaches both the Northern Doki River and Fujimi Vicinities within Marugame, where it merges into the Seto Inland Sea. At times parts of the river dry up due to the dry climate in Kagawa and a man-made channel modification which shortened the river.
