MADHOUSE Inc. (株式会社 マッドハウス, Kabushiki-gaisha Maddohausu) is a Japanese animation studio, founded in 1972 by ex–Mushi Pro animators including Masao Maruyama, Osamu Dezaki, Rintaro, and Yoshiaki Kawajiri. It has created and helped to produce many well known shows, starting with TV anime series Ace o Nerae! in 1973, and including western favourites Ninja Scroll, Vampire Hunter D: Bloodlust, Trigun and Di Gi Charat. Unlike other studios founded at this time such as AIC and J.C.Staff, their strength was and is primarily in TV shows and theatrical features. Expanding from the initial Mushi Pro staff, Madhouse recruited such important directors as Morio Asaka, Masayuki Kojima, and Satoshi Kon during the 1990s. Their staff roster expanded in the 2000s to include Mamoru Hosoda, Takeshi Koike, and Mitsuo Iso, as well as many younger television directors. The studio was also responsible for the first Beyblade anime series as well as the Dragon Drive anime.
The studio often collaborates with known manga artists, including Naoki Urasawa and Clamp. Madhouse produced adaptations of Urasawa's Yawara!, Master Keaton and Monster, with Masayuki Kojima helming the later two. The company has animated a number of CLAMP's titles, including Tokyo Babylon, two versions of X, Cardcaptor Sakura, Chobits, CLAMP in Wonderland, and most recently Kobato.
