In 2000 the South Korean government introduced a new system for romanization of Korean place-names, with implementation from 2000 to 2005.
National Geographic maps use the new transliteration system, often giving the old name for larger cities in parentheses, for example:
Busan (Pusan) and Jeju (Cheju)
The place-names for North Korea have not changed.
