Keiko is said to be the most common
given name for
Japanese women. However, this is slightly complicated by the fact that there are 46 different ways to spell it in
kanji, each carrying its own connotation.
Some famous Keikos include pianist Matsui Keiko, Keiko the Orca from Free Willy, and Keiko O'Brien from Deep Space Nine.
