Busan (Officially Busan Metropolitan City), formerly spelled Pusan (Korean pronunciation: [pusan]) is South Korea’s second largest metropolis after Seoul, with a population of around 3.6 million. It is the largest port city in South Korea and the fifth largest port in the world. The city is located on the southeasternmost tip of the Korean peninsula and faces the Korea Strait. The most densely built up areas of the city are situated in a number of narrow valleys between the Nakdong River and Suyeong River, with mountains separating some of the districts. Administratively, it is designated as a Metropolitan City. The Busan metropolitan area is divided into 15 major administrative districts and a single county.
Busan was the host city of the 2002 Asian Games and APEC 2005 Korea. It was also one of the host cities for the 2002 FIFA World Cup, and is a center for international conventions in Korea. On November 14, 2005, the city officially announced its bid to host the 2020 Summer Olympics Games.
Busan is home to the world’s largest department store, the Shinsegae Centum City and is pursuing a large number of multi-skyscraper projects, including the 110-floor, 510m-supertall Lotte Super Tower, which is slated to become the world’s third tallest building in 2013, after Burj Khalifa in Dubai and Taipei 101 in Taipei, Taiwan.
