Jieun Kim shares Pokémon Pokopia’s composer credit with Hiromu Akaba.
The game’s listed composers are Hiromu Akaba and Jieun Kim. Their work supports Pokopia’s relaxed atmosphere, which contrasts with the more battle-driven musical identity often associated with mainline Pokémon role-playing games.
Music is especially important in a life-simulation game because players may spend long periods gathering resources, decorating spaces, gardening, or simply exploring. A soundtrack can help establish the calm, welcoming mood that defines those activities.
Several other composers are strongly associated with Pokémon or Japanese game music, so the credit can be easy to misremember. Junichi Masuda has composed and produced music for earlier Pokémon projects, while Go Ichinose is another Pokémon composer. Toby Fox has contributed music to other Pokémon-related projects, but he is not the second composer credited for Pokopia.
