The Nameri River (滑川, Nameri-gawa) is a river that goes from the Asaina Pass in northern Kamakura, Kanagawa to the beach in Yuigahama, for a total length of about 8 km. Although Yuigahama is in fact the name of the entire 3.2 km beach that goes from Inamuragasaki to Zaimokuza's Iijima cape, the name is usually used just for its half west of the Namerigawa river's estuary, while the eastern half is called Zaimokuza Beach (材木座海岸).
