Junichi Masuda

History

Junichi Masuda was born on January 12, 1968, in Kanagawa Prefecture, Japan. He grew up playing video games and became interested in both music and programming — a combination of skills that was unusual and, as it turned out, precisely what a small startup called Game Freak needed. He joined the company in 1989, becoming one of its earliest employees, at a point when Game Freak was still primarily known as a video game magazine before it transitioned into game development.

Masuda's first major project as composer was Pulseman (1994), a Sega Mega Drive game developed by Game Freak. The soundtrack demonstrated his ability to write punchy, memorable themes within the strict technical constraints of console sound hardware. But the work that would define his career came next: the entire soundtrack for Pokémon Red and Green (1996), written for the original Game Boy. The Game Boy's sound chip offered four channels — two pulse wave generators, a wave channel, and a noise generator — and within those constraints Masuda wrote the overworld theme, the battle themes, the town themes, and the brief melodic gestures that each became inseparable from the Pokémon experience. The music worked because it was designed to be looped indefinitely without becoming irritating, which required both compositional skill and a precise psychological understanding of how music feels over time.

Pokémon Red and Green sold 10 million copies in Japan alone and went on to become one of the best-selling franchises in entertainment history. The music Masuda wrote for the original games traveled with that success — into the animated series, into merchandise, into the cultural memory of an entire generation of players in Japan, North America, Europe, and beyond. By the time the international release arrived as Pokémon Red and Blue in 1998, the melodies were already part of something larger than any single game.

As the Pokémon series grew, Masuda transitioned from composer to director — a relatively unusual career path, but one that made sense for someone who understood the franchise at a foundational level. His directorial credits include Pokémon Ruby and Sapphire (2002), which introduced the third generation and the Hoenn region; Pokémon Diamond and Pearl (2006), which brought Pokémon to the Nintendo DS with full touchscreen and wireless functionality; HeartGold and SoulSilver (2009), remakes of the beloved Gold and Silver titles that many players consider the high point of the series; Pokémon X and Y (2013), which brought the franchise to full 3D on the Nintendo 3DS; and Omega Ruby and Alpha Sapphire (2014). Each generation expanded the franchise while attempting to preserve the core loop — catch, train, battle, trade — that Masuda had helped design from the beginning.

Throughout his directorial work, Masuda has been vocal about the philosophy he brings to Pokémon design. He has spoken consistently about the franchise's founding intention: to recreate, for children growing up in an urbanizing Japan, the experience of catching insects in the wild that was disappearing from their everyday lives. That origin — childhood exploration, the pleasure of finding something alive and unexpected — remained the north star of his design decisions even as the series scaled to hundreds of millions of players. The music, composed for a single Game Boy cartridge in 1995, was already an expression of that intention: it made the world feel worth exploring.

Masuda later became CEO of Game Freak, a position that gave him oversight of the studio's direction as both a creative and business entity. His career is a case study in what it means to stay with a project long enough to understand it from every angle — composer, director, executive — and to carry the founding intentions forward through decades of technological change. The Pokémon franchise generated more than $150 billion in lifetime revenue across all media as of the mid-2020s, making it the highest-grossing media franchise of all time. The Game Boy soundtrack Masuda wrote in his late twenties is, in a precise sense, the sonic foundation of that entire edifice.
