Sansha River

The Sansha River [山下免; さんしゃ・み] is a river which runs through the central western region of Heisai Prefecture. Its source lies in the slopes of Mount Ōsan and it is one of the longest rivers in the prefecture.
Although the river discharges into the Yamawa Valley, it has a number of smaller tributaries which flow further south to Lake Ōtsuke. Sansha's original route was also changed as part of the massive land reclamation and flood control works undertaken by the Monda administration in the 17th and 18th centuries.
