Shisui River

The Shisui River (しすい认; shisui-tou) is the closest river to the north of the city of Akadami. It originates from Mount Musato in the Shidomo Mountains and flows through both Hokori and Taishi. It has four main tributaries: Kyokusui, Mangtarai and Tasachi. It reaches the Pacific Ocean at the top of Miyomashi.

The name of the river literally means 'white water', however the name is written in pure sangji as it is a proper noun. Some historical documents will refer to the Shisui using kaiko, however this is very rare practice nowadays.

The Shisui River is a popular icon of 20th century media. In the poetry anthology Cold Wind published by Akau Ri in 1957, the Shisui is commonly referenced as a symbol of Miyoirito. However, the river has been used as a representative of the prefecture for hundreds of years. Many folk songs and tales also mention the Shisui, the most well-known being Cross the Shisui Bridge (しすい币仔) a children's play song written in the late 17th century.
