Zaimokuza (材木座) is an area within the Kamakura, Kanagawa Pref., in Japan that runs along the sea from Cape Iijima near Kotsubo harbor to the estuary of the Namerigawa. The relation between the beach's name and that of its neighboring areas is complex. Although Yuigahama is in fact the entire 3.2 km beach that goes from Inamuragasaki to Zaimokuza's Iijima cape, the name is usually used to indicate just its half west of the Namerigawa river, while the eastern half is called Zaimokuza Beach (材木座海岸).
