Jaewoo is of Korean origin, translating to 'One who excels'. It's a unisex name, but it's more commonly used for males. The name consists of two parts: 'Jae', meaning 'one' or 'excellent', and 'Woo', which can be interpreted as 'rain'. Traditionally, Korean names have no family name and are not divided into first and last names like Western naming conventions. Instead, the given name comes before the surname when written in English. However, in Korean, it's typically written with the surname first, followed by the given name(s). Jaewoo is often spelled as 'Jaewu' or 'Jae-woo', with variations in spelling and spacing depending on personal preference or style guides. The name has gained international recognition due to the increasing popularity of Korean culture worldwide, particularly through K-pop music, Korean dramas (K-dramas), and movies like "Train to Busan" featuring a character named Jaesoo, though it's pronounced slightly differently from Jaewoo.
The name Jaewoo has had a consistent presence over the years with exactly five babies named Jaewoo each year from 2003 onwards, making a total of five individuals bearing this name since then.
