The Hii River (斐伊川, Hii-kawa) is a river on the island of Honshu in Shimane Prefecture and Tottori Prefecture, Japan.[1] With a length of 153 km and catchment of 2540 km2, it is the largest river in the east of Shimane Prefecture.[2][3] It flows through the cities of Izumo and Matsue and through the lakes Shinji and Nakaumi and discharges into the Sea of Japan.[3]
In antiquity the river was known as "Izumo-no-okawa" (出雲大川, "The great Izumo river").[4][5]
The River Hii significantly changed its course and transformed the land several times during last 7 millennia.[6] Alluvial deposits carried by the river joined the Shimane peninsula to the mainland, which may have been represented in the "Kunibiki-shinwa" myth.[6][7] Since the 17th century it flows into lake Shinji, and since the early 20th century continues to the Sea of Japan.[6][7] Hii river frequently caused floods in its catchment. On the other hand, it was and currently is an important source of drinking and irrigation water.[6][7] During the Edo period the upper Hii catchment was the largest iron-producing region in Japan.[8] Nowadays the river is dammed for the production of hydropower. The largest dams are Obara and Hinobori.[7]
