Kengo is a unisex given name of Japanese origin, derived from the kanji characters golden and strong. It has been traditionally used more frequently for males but can also be found among females. The name Kengo gained popularity in Japan during the mid-20th century, with its usage peaking in the 1970s before declining somewhat in recent years. However, it remains a popular choice for parents seeking a strong and distinctive name for their child. Internationally, Kengo is most commonly encountered in East Asian communities but has also been adopted by families elsewhere who appreciate its unique sound and meaning.
The name Kengo experienced a notable resurgence from the mid-90s onwards, with peaks in popularity occurring in 1992, 1994, and 2015. However, it appears to have been less favored during the early to mid-20th century, as evidenced by the lower birth counts in 1920 and between 1996 and 2012. Overall, the name has seen a total of 71 births over the recorded period.
