Kenji Yamamoto (composer born 1958)

Kenji Yamamoto (山本 健司, Yamamoto Kenji, born July 1, 1958) is a Japanese music composer and arranger who has been responsible for producing and composing soundtracks, including opening and ending sequence themes for various anime, tokusatsu and video game projects in the 1980s, 1990s and 2000s. Most notably, he has worked on soundtracks of various Dragon Ball video games.
Yamamoto has also composed background music for Dragon Ball Kai, a revamped version of the anime series Dragon Ball Z. On March 9, 2011, Toei Animation publicly acknowledged that many of Yamamoto's musical works for the series infringed upon unidentified third-party copyrights. As a result, Toei removed Yamamoto and replaced his compositions with those from the original Dragon Ball Z series written by Shunsuke Kikuchi. The plagiarism of these works have been known to fans since May 2010. His compositions in the games were also replaced.
