Masaaki Endoh
Mizuki performed theme songs throughout the 1980s and 1990s, for shows such as "Beast King GoLion", "Getter Robo Go", and "Jikuu Senshi Spielban", his work not as extensive until 2000. On July 17, 2000, with fellow "anison" vocalists Hironobu Kageyama ("Dragon Ball Z"), Masaaki Endoh ("The King of Braves GaoGaiGar"), Eizo Sakamoto (vocalist of ANTHEM and Animetal), and Rica Matsumoto ("Pokémon"), he formed the "supergroup" JAM Project. He later reduced his membership in the group to "part-time", allowing for the entry of Hiroshi Kitadani ("One Piece"), Masami Okui ("Revolutionary Girl Utena"), and Yoshiki Fukuyama ("Macross 7" as Basara Nekki's in Fire Bomber).
