Seoul
3This city of 10 million has rapidly emerged as both a political and economic powerhouse not just in South Korea but in Asia at large. Add in the nearby suburbs and Seoul instantly becomes a city of 20 million, second only to Tokyo in terms of urban sprawl. Once the capital of the entire Korean peninsula before Japanese occupation during World War II, Seoul managed to survive multiple wars and maintain its illustrious and unique character. Driven by engagement with the west, Seoul is also one of the most liberal and forward-thinking cities in Asia. Excellent public transportation, world-class dining, fantastic sites, and intense night-life make Seoul a must-visit city.
