Hironobu Kageyama is a Japanese musician, singer and composer. He is best known for his work on anime, video game and tokusatsu soundtracks. Kageyama first rose to prominence as a teenager in the 1970s as lead singer of the rock band Lazy. Following their breakup in 1981, Kageyama began a solo career. He struggled until finding major success in the mid-1980s, when he started singing theme songs for anime and tokusatsu television shows. The music to such programs is called anison in Japan, and Kageyama became immensely popular, earning the nickname "Prince of the Anison World".
Kageyama's best known works include the title tracks for Dengeki Sentai Changeman and Hikari Sentai Maskman, "Saint Shinwa ~Soldier Dream~" for Saint Seiya, and "Cha-La Head-Cha-La" for Dragon Ball Z. Lazy reunited in 1997, and Kageyama briefly worked with Masaaki Endoh as the duo Metal Brothers before they formed the anison supergroup JAM Project in 2000 with several other vocalists.
