The majority of the South Korean tourist industry is supported by domestic tourism. Thanks to the country's extensive network of trains and buses, most of the country lies within a day's round trip of any major city. International tourists come primarily from nearby countries in Asia. Japan, China, Hong Kong and Taiwan together account for roughly 75% of the total number of international tourists.[3] In addition, the Korean wave has brought increasing numbers of tourists from Southeast Asia and India. The Korea Tourism Organization (KTO) is targeting 100,000 arrivals from India in 2013.[4]
International tourists typically enter the country through Incheon International Airport, near Seoul, which was found to be the world's best airport in 2006.[5] Also international airports in Busan and Jeju are frequently used.
