Hino River (Tottori Prefecture, Japan)

Course and characteristics

From its mountain source the Hino River initially flows toward the east-northeast and, after passing through the Kofu area, shifts to a north-northwest direction as it approaches the coast. The lower reaches form an estuarine transition to Miho Bay, contributing freshwater inflow to the coastal zone. Along its course the river crosses a mixture of upland terrain, cultivated valley floors and built-up towns.

Uses and importance

The river is a vital freshwater resource for communities in its basin. Approximately 60,800 people rely on the Hino River for domestic and agricultural water supplies. Local farmers use its water for irrigation, while towns draw on it for municipal needs. The river’s estuary and adjacent wetlands also support fisheries and provide habitat for a variety of aquatic and bird species.

Management, flood control and environmental considerations

Because the Hino River basin combines steep uplands with narrow plains, the river has been subject to flood-control and river-improvement projects. Measures such as levees, channel maintenance and other works have been implemented to reduce flood risk, protect settlements and stabilize flows. Efforts to balance engineering needs with ecological conservation are part of ongoing river management.

Historical and regional context

Historically, the river has shaped settlement and agricultural patterns in western Tottori. Towns and rice paddies developed along its valley where water was accessible and soils were fertile. The river remains an important feature of local identity and land use planning in the region.
