Junichi Masuda (増田 順一, Masuda Jun'ichi, born January 12, 1968) is a Japanese video game composer, director, designer, producer, singer, programmer and trombonist, best known for his work in the Pokémon franchise. He is a member of the Game Freak board of directors, and has been employed at the company since 1989 when he founded it alongside Satoshi Tajiri and Ken Sugimori.
With the development of new Pokémon games, Masuda took new roles in future projects. He began to produce and direct games, starting with Pokémon Ruby and Sapphire, and became responsible for approving new character models. His style seeks to keep games accessible while still adding increasing levels of complexity. His work sticks to older mainstays of the series, including a focus on handheld game consoles and 2D graphics. His music draws inspiration from the work of modern celebrated composers like Dmitri Shostakovich, though he used the Super Mario series as a model of good video game composition.
