Happiness, light, or peace
In Japanese, Ko is a versatile name often used as a prefix or suffix, but as a standalone name, it frequently derives from kanji meaning 'happiness', 'light', or 'peace'. It is also found in Burmese culture, where it is used as a respectful title or name meaning 'brother'. In a Western context, it is often chosen for its minimalist, modern appeal.
