It is the only Class A river within Kagawa Prefecture. The river was named after Doki Village (土器村 ''Dokimura''), which is presently known as the Doki vicinity or neighborhood within Marugame. Doki Village was located at the source of the river, and clay from there used to be made into earthenware goods (the Japanese word ''doki'' {{nowrap|[土器]}} means "pottery" or "earthenware"). The central portion or the river is called ''haraikawa'' (祓川), which is a river in which worshippers purify themselves before praying.<ref>『われら土器川探検隊』、建設省四国地方建設局香川工事事務所、企画・発行 (''Our Doki River Expedition Team'', a children's book published by the Kagawa Construction Office within the Shikoku Construction Bureau, Ministry of Construction)</ref>
== Geography == The source of the Doki River is located on Mt. Ryuo (town of Mannō, Katsuura vicinity) 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.
