Kanji and meaning
The "ko" in Seiko is generally written with a kanji meaning "child" (子), and in that case is exclusively feminine; the kanji for "Sei" varies, for example:
晴子 ("clear weather"); also read Haruko
正子 ("upright", "correct"); also read Masako or Shōko, and also used in Korean to write the name Jeong-ja
清子 ("clean", "pure"); also read Kiyoko or Sayako
聖子 ("holy"); also read Kiyoko or Shōko, and also used in Korean to write the name Seong-ja
青子 ("blue" or "green"); also read Aoko
Rarely, the "ko" may be written with a kanji meaning "lake" (湖). Written this way, the name may be either masculine or feminine.
