The Korean Peninsula lies in the center of Northeast Asia. The coordinates of its capital, Seoul, are 37.34° N and 126.59° E, putting it in close proximity to the Yellow Sea. Seoul is within a three-hour flight from 43 cities with populations of over one million people. Korea’s location between China and Japan has been a great geographical advantage for the nation.
There are 25 autonomous districts and 423 administrative “dong” units in Seoul. The city covers 0.28% of the entire peninsula (or 0.61% of South Korea), and spans an area 30.30 km north-to-south and 34.78 km west-to-east.
