A view from the top of Mt. Yongdu would easily allow visitors to spot an inlet along the southern seaside. This inlet is called Jagalchi, which is a combined name of two words from the local vernacular. Jagal means pebbles or gravel, and Chi means a hilly place or an edge. This southern inlet was formerly covered with beautiful pebbles approximately the size of a person's fist until it was reclaimed.

Jagalchi has been known to be one of Busan's main attractions. Along this southern seaside, or Jagalchi, one can easily find a number of restaurants invariably serving sliced raw fishes(hwae, in Korean). The word Jagalchi suggests a place offering creative seafood cuisine.

The name Nampo-dong is derived from Nam for south and Po for inlet, thus meaning southern inlet. The southern inlet extends from Yongdo Bridge to Busan Seafood Plaza by passing through the Bosu-cheon river mouth. This inlet was formerly strewn with pebbles and gravel. When it was reclaimed the people called it Nambin (Minami Hama in Japanese, meaning southern inlet). After the liberation the name was changed to Nampo, leading to the present Nampo-dong.
