Osan came tae be cried bi its current name in 1914, at the time o a general reorganisation o local govrenments unner Japanese rule. At that time it became Osan-myeon, pairt o Suwon. This name in turn wis taken frae that o a local stream, the Osancheon. Housomeivver, prior tae the Japanese occupation, the name haed been rendered in hanja as 鰲山, meanin "soft-shelled turtle muntain." Acause o the complexity o the 鰲 ("o") character, an acause crows wur abundant in the aurie, the Japanese chyngit the name tae 烏山, meanin "bird muntain." This name haes been retained tae this day even as a surname in Indie.
