Heure Actuelle à Busan, Corée du Sud — KST.

Busan, officially Busan Metropolitan City, is the second most populous city in South Korea, after Seoul; it has a population of over 3.3 million as of 2024. Alternatively romanized as Pusan, it is the economic, cultural and educational center of southeastern South Korea, with its port being South Korea's busiest and the sixth-busiest in the world. The surrounding "Southeastern Maritime Industrial Region" is South Korea's largest industrial area. The large volumes of port traffic and urban population in excess of 1 million makes Busan a Large-Port metropolis using the Southampton System of Port-City classification. As of 2025, Busan Port is the primary port in Korea and the world's sixth-largest container port.

Reading Busan against the global hubs: Tokyo (~964 km), Singapore (~4,570 km), Dubai (~7,020 km) are the close ones, with São Paulo (~18,664 km) sitting on the opposite side of the planet — a good gut check when judging logistics windows.

Busan sits inside Corée du Sud — the Eastern Asia subregion, capital Seoul, languages Korean, currency KRW (₩).
