Ansan, South Korea

With a population of 767,000, Ansan is no quaint Korean suburb. This industrial hub on the Yellow Sea coast has seen rapid growth, but bureaucracy is a persistent headache. While the city boasts rail connections to Seoul and a multicultural vibe, the weather can be punishing, with frigid, dry winters and sweltering, rainy summers. Ansan may appeal to those drawn to its manufacturing jobs and lower costs, but it's no picturesque paradise.
