Names

The name "Busan" is the Revised Romanization of the city's Korean name since the late 15th century. It officially replaced the earlier McCune-Reischauer romanization Pusan (푸산) in 2000. During the Japanese occupation it was spelled "Fuzan".

The name 釜山 (now written 부산 using the Korean alphabet) is Sino-Korean for "Cauldron Mountain", believed to be a former name of Mt Hwangryeong (황령 산, 荒嶺 山, Hwangryeong-san) west of the city center. The area's ancient state Mt Geochil (거칠산 국, 居柒山 國, Geochilsan-guk, "Rough-Mountain Land") is similarly thought to refer to the same mountain, which towers over the town's harbor on the Suyeong. (The later Silla district of Geochilsan-gun was renamed Dongnae in 757.)
