GAINAX Co., Ltd. is a Japanese anime studio famous for productions such as Neon Genesis Evangelion, Royal Space Force, Gunbuster, Nadia: The Secret of Blue Water, Kare Kano, FLCL, Magical Shopping Arcade Abenobashi, and Gurren Lagann, which have garnered critical acclaim and commercial success. Evangelion has reportedly grossed over 150 billion yen, or approximately US$1.2 billion. In a discussion at the 2006 Tekkoshocon, Matt Greenfield claimed that Evangelion had grossed over US$2 billion; Takeda reiterated in 2002 that “It sold record numbers of laserdiscs in Japan, and the DVD is still selling well today”, as well as for their association with award-winning anime director and studio co-founder Hideaki Anno. The company is headquartered in Koganei, Tokyo. Until Neon Genesis Evangelion, Gainax typically worked on stories created in-house, but the studio has increasingly developed anime adaptations of existing manga like Kareshi Kanojo no Jijou and Mahoromatic.
