An-Nyeong Ha-Se-Yo, Busan!
Busan, South Korea's second city, doesn't approach Seoul in terms of size or global influence, but is home to a metropolitan population of 3.6 million, and one of the busiest ports in the world. Busan is found on the south-eastern end of the peninsula, closer to Japan than the capital. An important business center full of suits, concrete and convention halls, Busan also boasts popular beaches, nature reserves and an urban landscape shaped by green mountains that pop up almost randomly amid the skyscrapers.
