Where does the name Busan (city in Korea) come from?
"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).
