OLM animated the Pokémon TV series.
OLM, Inc. is a Japanese animation studio founded in 1994. It became closely associated with Pokémon after producing the television anime that began broadcasting in Japan in 1997. The studio’s work helped establish the visual style of the franchise across its earliest television seasons and films.
The Pokémon anime has involved many production partners, including broadcasters, distributors, and overseas localization companies. However, OLM is the key animation studio most strongly identified with the long-running television series, especially its foundational years.
A common mix-up is naming Nintendo, Game Freak, or The Pokémon Company as the animator. Those organizations are central to Pokémon’s games, ownership, or franchise management, but OLM is the animation studio credited with producing the television anime.
