Kenja is a unique Japanese name meaning "someone connected with swords," derived from "ken" (sword) and "-ja" (belonging). Historically, it was given to skilled samurai warriors in feudal Japan, associated with strength, courage, wisdom, and agility in battle. Today, Kenja is respected and admired in Japan, often used for males but also sometimes for females. Outside of Japan, it's relatively rare yet gaining attention due to its unique sound and meaning.
