Daejeon is South Korea's fifth largest metropolis and the provincial capital of Chungnam. Daejeon had a population of over 1.5 million in 2010. Located in the center of Korea, Daejeon serves as a hub of transportation. It is at the crossroads of Gyeongbu railway, Honam railway, Gyeongbu Expressway, and Honam Expressway. With this transportation network, other major cities are accessible within 2 hours and Seoul is only 50 minutes by high speed train from Daejeon. Korail (Korea Railroad Corporation), K-water (Korea Water Resources Corporation) and KOMSCO (Korea Minting & Security Printing Corporation) are headquartered in Daejeon. Daejeon serves as an administration hub with the National Government Complex. The Korean administration in the 1980s decided to relocate some of its functions from Seoul, the national capital, to other cities.
