Kenji Yamazaki' is a Japanese composer. He started off working on music for games at age 25 while he was still in school as a part-time job, but he eventually started to do it professionally. He worked primarily for Tamtex, Micronics, and Biox. His first work was for the second Kaiketsu Yancha Maru game. Yamazaki thought it was funny that he was being paid for composing music for games.
Yamazaki still composes music for games to this day, mostly for mobile phones.
Kenji used a Yamaha SY77 keyboard to play back his music. He used a Roland MC-300 to sequence the music. Then, he wrote the music down on sheet music paper and sent it to the developers. It was then programmed into the game by Hiroto Nakamura.
