Where does the name Busan (city in Korea) come from?
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 in 2000. During the Japanese period 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 (황령산, 荒嶺山, Hwangryeong-san) west of the city center. The area's ancient state Mt Geochil (거칠산국, 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.)
"Busan" is the romanization of the city's Korean name - 부산.  Previously, the name was romanized as "Pusan" until it was officially replaced in 2000.  The meaning of the name in Sino-Korean is "Cauldron Mountain", believed to be the former name of a nearby mountain now known as Mt Hwangryeong (황령산).
