People
Composer, artist, co-composer - the people behind the music.
Yuzo Koshiro
Born 12 December 1967, Japan
Yuzo Koshiro began his professional composing career at Nihon Falcom at the age of 16–17, making him one of the youngest major composers in the Japanese game industry. His early Falcom work demonstrated an unusual maturity - the scores for Ys I and Ys II are not merely good game music; they are compositionally sophisticated works that hold up against any standard.
What sets Koshiro apart is the breadth of his range. His Mega Drive work - particularly Streets of Rage 2 - is rooted in contemporary European club music: techno, house, jungle. His SNES work - ActRaiser - is cinematic and orchestral, drawing on classical structure. Most composers are strong in one register; Koshiro is exceptional in both.
Koshiro is also notable as a programmer. He built the custom sequencer used to compose the Streets of Rage trilogy - a tool that gave him precise control over the YM2612 FM chip at a level most composers working through the standard Mega Drive driver would not have had. This dual composer-programmer identity runs through his career: the music is shaped by deep technical understanding of the hardware it plays on.
He co-founded Ancient Corp in 1990 with his sister Ayano. The company has been his primary creative vehicle since, producing the SoR trilogy, Beyond Oasis, and numerous other titles. As of 2024, Ancient Corp remains active and Koshiro continues to compose.

Ayano Koshiro
Yuzo's sister; Falcom graphic artist; Ancient Corp director
Ayano Koshiro joined Nihon Falcom as a graphic artist during the same period Yuzo was composing there in the mid-1980s. She provided character design and pixel art for the Streets of Rage trilogy - the visual identity of the series is inseparable from her work.
She co-founded Ancient Corp in 1990 alongside Yuzo and served as director on Beyond Oasis (1994) - one of the relatively few major Mega Drive releases directed by a woman. Her influence on the creative direction of Ancient Corp's output extends well beyond her art credits.

Motohiro Kawashima
Co-composer on Bare Knuckle III (Streets of Rage 3, 1994)
Motohiro Kawashima co-composed Streets of Rage 3 (Bare Knuckle III) alongside Yuzo Koshiro. The SoR3 soundtrack has a more experimental character than its predecessors - harsher, more dissonant in places, with a wider stylistic range. Kawashima's contribution is confirmed in the game's ending credits and in the VGMdb and MobyGames entries for the title.
Note: detailed biographical information on Kawashima outside the SoR3 context is limited in public sources. The co-composer credit is verified; background beyond it is not available here.
Ancient Corp (株式会社エインシャント)
Founded 1990 · Tokyo, Japan · active as of 2024
Ancient Corp was founded in 1990 by Yuzo and Ayano Koshiro. The company's primary focus has been game development with Yuzo Koshiro composing - a model that gave him direct control over both the creative and commercial dimensions of his work, unusual for a composer of his era.
Ancient Corp developed the Streets of Rage trilogy in collaboration with Sega, directed Beyond Oasis, and has continued producing titles through to the present. The company's website (ancient.co.jp) documents ongoing work.
