Kazuma Jinnouchi



Kazuma Jinnouchi is a Japanese music composer, and a former composer and supervisor at 343 Industries.

He previously worked with Konami and Kojima Productions on Metal Gear Solid 4: Guns of the Patriots and Metal Gear Solid: Peace Walker.

He then moved to the United States and, in July 2011, began working with 343 Industries on Halo 4, along with composer Neil Davidge. However, contrary to Davidge, Jinnouchi is an integral part of the studio's audio team. He composed several tracks 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, and went on to compose most of the Halo 5: Guardians soundtrack.

Jinnouchi also composed some of the soundtrack of Halo Infinite, but on July 13, 2018 he announced that he had left 343 Industries to become a freelancer composer.
