The name Kage originates from the Japanese language and culture. It is a unisex name that can be used for both males and females. The word "kage" in Japanese literally translates to "shadow" or "shade." It is believed that the name was initially used to describe a person's calm and composed demeanor, like the tranquility of a shadow.

One of the earliest recorded uses of the name Kage can be found in ancient Japanese literature and poetry from the 8th century AD. In the classic anthology of Japanese poetry, the "Manyoshu," there are several references to the word "kage" being used as a metaphor for fleeting moments and the transient nature of life.

The name Kage gained popularity during the Edo period (1603-1868) in Japan, particularly among the samurai warrior class. It was considered a strong and honorable name, reflecting the ideals of discipline, loyalty, and courage. One notable historical figure with the name Kage was Kage Munenaga, a renowned samurai and military strategist who lived in the 16th century.

Kage Nobuyoshi (1776-1850) was a celebrated ukiyo-e woodblock print artist, known for his depictions of kabuki actors and landscapes.

Outside of Japan, the name Kage has also been used, albeit less frequently. One notable example is Kage Baker (1952-2010), an American science fiction and fantasy writer renowned for her "Company" series of novels.
