Shiba River - History

History

Originally, the river flew into a wetland at the current region of Minuma. In 1629, a civil engineering project by Ina Tadaharu (伊奈 忠治?) created a reservoir and blocked the flow. In 1727, the reservoir levee was demolished to open up the area for creating rice paddies. In 1728, the lowest sections of the area were gouged to allow for the passage of water, which set the current position of the river.
