Seiko (given name)

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:[1]

• 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.[1]
