Which composer wrote the music for Pokémon Red and Green?

Junichi Masuda composed the music for Pokémon Red and Green.

Masuda joined Game Freak and worked as a programmer and composer on the first Pokémon games. His music helped define the series’ early sound, including town themes, battle music, and the memorable opening sequence. He also contributed programming and design work to the original titles.

Masuda’s Pokémon career extended far beyond the first games. He later directed and produced multiple main-series entries and became one of the franchise’s best-known creative leaders. His involvement makes him a frequent answer in questions about Pokémon music and game development.

The composer is sometimes confused with Satoshi Tajiri, who created the concept and directed the first games, or Ken Sugimori, who created much of the visual design. They were all central to Game Freak’s early team, but Masuda specifically composed the original game soundtrack.
