Hiromu Akaba is credited as a composer for Pokémon Pokopia alongside Jieun Kim.
The soundtrack credits identify Akaba and Kim as the game’s composers. Music is especially important in a slow-life simulation because it helps distinguish exploration, construction, relaxation, and interactions with Pokémon without relying solely on battle themes.
This credit should not be confused with the many composers associated with the wider Pokémon franchise. Junichi Masuda, Go Ichinose, and Shota Kageyama have all worked on Pokémon music in other projects, but Pokopia’s listed composer credit includes Hiromu Akaba and Jieun Kim.
The question asks for one specific composer, so the correct answer is Hiromu Akaba rather than the complete two-person credit. Composer credits describe the music team, while the game’s director, writer, artist, and programmer credits refer to different creative and technical responsibilities.
