is a Japanese pop rock and kayōkyoku band.
Crystal King originally consisted of vocalists and Masayuki Tanaka, guitarist, pianist, keyboardist, drummer, and bassist . The band saw its first commercial success at the end of 1979 with debut single "Daitokai", which sold 1.5 million copies, winning two popular song festivals, (18th Yamaha Popular Song Contest and 10th World Popular Song Festival in Tokyo). Other successful singles included "Shinkirō" in 1980 (750,000 copies sold), "Shojo Kōkai" (1980), "Passion-Lady" (1981), "Ceccile" (1982) and "Setouchi kōshinkyoku (IN THE MOOD)" (1984).
Internationally, the band are best known for writing and performing the first two songs of the anime Fist of the North Star, "Ai o Torimodose!!" and "Yuria ... Eien ni". The original single of 1984 sold more than 500,000 copies, rising to over 1 million copies including later versions and re-releases.
In 1986, Tanaka left Crystal King to launch a solo career. However, in June 1989 he lost his voice after being struck in the throat by a baseball, and never regained his original three-octave vocal range. The rest of the band performs as, reuniting with Tanaka on occasion.
The band broke up in 1995, and vocalist Yoshisaki continued performing as Crystal King as a solo project.
