Reiko is of Japanese origin and has a beautifully balanced rhythm to its sound, with the syllables "rei" and "ko" flowing smoothly into each other. This name holds significant cultural value in Japan, where it's often used for girls born during the Reiwa era, which began on May 1st, 2019, marking the start of a new era under Emperor Naruhito. The name Reiko itself is composed of two kanji characters: "rei" meaning "wise" or "good," and "ko" meaning "child." Thus, Reiko can be interpreted as "wise child," expressing hope for wisdom and growth in one's offspring.
The name Reiko experienced a gap of over three decades between its appearances among newborns in the United States, with six births recorded in both 1975 and 2008, and then reemerging in 2021 with seven births. Overall, there have been nineteen babies named Reiko since 1975.
