Wilhelm Grimm is a foundational figure in the world of anime and manga, not as a direct creator who worked in the medium, but as the original author of the fairy tales that have served as the basis for countless Japanese productions. Born in Hanau, Germany, in 1786, Wilhelm Carl Grimm, alongside his brother Jacob, was a German author and philologist whose collection of European folklore, commonly known as Grimms Fairy Tales, has become a perennial source of material for adaptation across global media.

In the context of Japanese anime, Wilhelm Grimm is consistently credited as an original creator or original story writer for numerous films, television series, and original video animations. This credit reflects the fact that his published tales form the foundational narrative and character concepts for these works. The scope of these adaptations is broad, spanning from the 1970s to the present day.

One of the notable early anime productions credited to the Grimms is the 1987 film Grimm Douwa: Kin no Tori, also known as Grimms Fairy Tales: The Golden Bird. This feature-length anime, directed by Toshio Hirata, is a direct adaptation of the Brothers Grimm story, with Wilhelm and Jacob Grimm officially credited as the source material creators. This film stands as a clear example of how their literary work was directly translated into the anime medium.

The breadth of their influence is further demonstrated by their credit on anthology series that adapt a wide range of classic tales. Both the World Fairy Tale Series, a 1995 television anime produced by Toei Animation, and the earlier World Famous Fairy Tale Series, which aired in Japan between 1975 and 1983, drew upon the Grimms collection for multiple episodes. For the World Fairy Tale Series, for instance, Wilhelm Grimm is credited as the original creator for seven of its twenty-six episodes, which included adaptations of stories like Hansel and Gretel and Snow White.

His name also appears in adaptations that blend the classic tales with established popular characters. The 1993 original video animation Hello Kitty in Snow White, part of the long-running Hello Kitty franchise, credits both Jacob and Wilhelm Grimm as the original creators, illustrating how their stories are used as the narrative framework for other intellectual properties. Similarly, the long-running manga series Kingdom Hearts and Kilala Princess have credited the Grimms as the original creators for storylines adapted from Snow White and Rapunzel.

The identity of Wilhelm Grimm as a creator in this space is that of a source author. His artistic identity is intrinsically linked to the body of work he compiled with his brother, characterized by archetypal characters, moral lessons, and narratives that explore both the fantastical and the harsh realities of their folk origins. The industry significance of the Grimms cannot be overstated; their fairy tales represent a foundational text for the fairy tale genre within anime and manga, providing a shared cultural lexicon that creators continue to reinterpret. This legacy extends to modern productions, such as the Netflix original anime series The Grimm Variations, which explicitly takes the stories collected by the Brothers Grimm as its starting point for new, often darker, reinterpretations.
