Kenji Yamamoto was fired by Toei Animation after the first 95 episodes of Dragon Ball Z Kai when Toei Animation publicly acknowledged that many of his compositions were infringed upon unidentified third-party copyrights which led to the show replacing his compositions with the compositions by Shunsuke Kikuchi throughout the entire series' run and even the first 95 episodes of Dragon Ball Z Kai.
Following the revelation of his BGM plagiarism situation, Kenji Yamamoto's activity is unknown as of today.
