Kazuma Jinnouchi
From Halopedia, the Halo wiki
Kazuma Jinnouchi is a music composer and supervisor at 343 Industries.[1]
He previously worked in Japan with Konami and Kojima Productions on Metal Gear Solid 4: Guns of the Patriots and Metal Gear Solid: Peace Walker.[2]
He then moved to the United States and, in July 2011, began working with 343 Industries on Halo 4, along with composer Neil Davidge.[3] However, contrary to Davidge, Jinnouchi is an integral part of the studio's audio team. He composed several musics for Halo 4: only one of his tracks was featured in Volume 1 of the Halo 4: Original Soundtrack, but nine were present in Volume 2. He also composed the music featured in the Halo Xbox One E3 announcement trailer,[4] and is slated to compose most of the Halo 5: Guardians soundtrack.[5]
