The name Ko, of Japanese origin, is derived from the kanji character 'Ko', which means 'small'. This single-character name has been traditionally used for both males and females in Japan, adding to its uniqueness.
Ko is quite uncommon as a given name. The statistics show that there were five babies named Ko born in 1988 and another five born in 1993. This results in a total of ten children with the name Ko over those two years.
