Keiko is a feminine Japanese given name.
As with many Japanese names, Keiko can be written using a number of different kanji. Some of the most common ways of writing Keiko (and the most representative meanings of the respective kanji) are:
恵子 — "lucky/blessed child"
敬子 — "respectful child"
景子 — "sunlight/view/scenic child"
桂子 — "katsura tree child"
圭子 — "square jewel child"
慶子 — "happy child"
啓子 — "open (one's eyes)/express/spring (season) child"
硅子 — "silicon child"
The suffix ko (子) implies the name is female and the name is almost never given to males. Much less commonly, Keiko can also be written as 螢子, 輕子, or 軽子.
