Rare Korean Surnames

Did you know there are 5,582 surnames in Korea now? This is 10 times the number of surnames recorded 15 years ago. 

For this reason, I used the survey that dates even further back to 2000 to show you the more traditional surnames that were used in Korea. At that time there were only 289 surnames in Korea, which makes each one quite unique.
