Masayuki Tanaka is a Japanese singer. He was born in Imari, Saga Prefecture. He is one of the two original vocalists of the band Crystal King, known for their anime soundtracks such as Fist of the North Star where Tanaka provided the vocals in the chorus of its opening theme. After leaving Crystal King, he started his solo career and along the line lost his voice after being struck in the throat by a baseball and was never able to regain his original vocal range. In the late 1990s and early 2000s, he worked on the soundtracks of the tokusatsu series Ultraman Gaia and Kamen Rider Kuuga. He is also featured on the Katamari Damacy soundtrack Katamari Fortissimo Damacy where he sings "Katamari on the Rock", the main theme of the game.
Tanaka has had his name variably written as 田中昌之 and 田中雅将 in his career, before choosing 田中雅之 in 2004, and then switching back to his birth name kanji in 2013.
Masayuki rerecorded on one of his greatest hits, Kamen Rider Kuuga's theme song with Rider Chips for the release of Heisei Kamen Rider 20 Titles Commemoration Best, which was released on May 1, 2019.
