Studio Deen

Studio Deen is a Japanese animation studio established in 1975 by Hiroshi Hasegawa, a former producer at Sunrise, together with other animators who had worked at that company. The business developed during the expansion of Japanese television animation and became involved in a broad range of commissioned and original productions, including television series, theatrical films, original video animations, and later web-based animation projects. The studio’s early work included assignments connected with established manga and anime properties. Its credits from the 1980s and 1990s include substantial participation in Urusei Yatsura, Maison Ikkoku, Ranma ½, Patlabor, Rurouni Kenshin, and You're Under Arrest. These projects helped establish Studio Deen as a flexible production house able to work across comedy, romance, action, science fiction, fantasy, and family-oriented programming. Rather than being identified with one single in-house franchise, the studio has generally operated through a portfolio of commissions and production partnerships. During the 2000s, Studio Deen expanded its television output and became associated with a wide variety of adaptations and genre series. Its credits include Fruits Basket, Gravitation, GetBackers, Full Moon o Sagashite, Hell Girl, Higurashi When They Cry, Fate/stay night, Maria-sama ga Miteru, Kyo Kara Maoh!, Junjo Romantica, Vampire Knight, and 07-Ghost. The company also continued producing OVAs and films, including installments and spin-offs connected with Hakuoki, Hetalia, Higurashi, Rurouni Kenshin, and The World's Greatest First Love. The studio’s production scope includes more than conventional television animation. It has produced theatrical features, direct-to-video works, online projects, and animation for internationally distributed properties. Examples include collaboration on Neo Yokio and the Samurai & Shogun specials for Rick and Morty, as well as participation in later Pretty Cure, Sailor Moon, and Seven Deadly Sins projects. It has also worked with other Japanese studios on selected productions, reflecting the collaborative structure common to large anime projects. Since April 2011, Studio Deen has operated as a subsidiary of IMA Group. The company also owns or operates specialist subsidiaries and affiliated production units: Danny Donghua, a Chinese subcontracting studio; Megumi, which handles digital work subcontracting; and Umidori, a 3DCG subcontracting studio. These units broaden the group’s capacity beyond traditional 2D animation and support the distributed workflow used in contemporary anime production. Studio Deen remains an active Japanese animation producer. Its recent and announced credits span adaptations, sequels, genre works, and collaborations with larger rights holders and production committees. The company’s continuing role is best understood as that of an established production studio and contractor whose value lies in long-term production experience, adaptation work, and access to specialized animation and digital-production resources.

Studio Deen was founded in 1975 by Hiroshi Hasegawa, formerly a producer at Sunrise, together with a group of animators who had also worked there. Its formation placed the company within the growing network of independent Japanese animation studios that supplied television broadcasters, publishers, toy companies, and production committees. In its first decades, Studio Deen built its reputation through participation in well-known television franchises and through commissioned production work. During the 1980s it contributed to Urusei Yatsura and worked on projects including Maison Ikkoku, F, and Ranma ½. The studio also participated in theatrical and OVA production, including Angel's Egg, Patlabor-related works, and later Ranma ½ projects. These credits showed a capacity to move between serialized television animation, feature production, and shorter-form home-video releases. The 1990s brought continued work on popular adaptations and a larger range of genres. Studio Deen produced or participated in titles such as You're Under Arrest, Rurouni Kenshin, Eat-Man, Zenki, Violinist of Hameln, and Houshin Engi. It also worked with other studios on selected projects, a practice that remained characteristic of its production model. Its OVA portfolio included works associated with Ranma ½, Rurouni Kenshin, DNA², and The Irresponsible Captain Tylor. From 2000 onward, the studio became particularly visible in television adaptations aimed at different audience segments. Its credits included Fruits Basket, Gravitation, GetBackers, Full Moon o Sagashite, Maria-sama ga Miteru, Kyo Kara Maoh!, Hell Girl, Fate/stay night, Higurashi When They Cry, Junjo Romantica, Vampire Knight, and 07-Ghost. The company continued to produce films and OVAs alongside television work, including Hakuoki, Hetalia, Sekai-ichi Hatsukoi, and later Higurashi releases. Studio Deen’s output in the 2010s covered both continuing properties and new adaptations. Important credits included KonoSuba, Nura: Rise of the Yokai Clan, Log Horizon 2, Descending Stories: Showa Genroku Rakugo Shinju, Hozuki's Coolheadedness, Junji Ito Collection, and The Reflection. The studio also contributed to projects involving international partners and established intellectual properties, including Neo Yokio and later Rick and Morty Samurai & Shogun specials. In April 2011, Studio Deen became a subsidiary of IMA Group. The broader group structure includes Danny Donghua in China, Megumi for digital subcontracting, and Umidori for 3DCG subcontracting. These businesses reflect the increasingly distributed nature of anime production, in which key animation, digital compositing, background work, and computer-generated imagery may be assigned across multiple specialist units. During the 2020s, Studio Deen continued working on television series, films, OVAs, and streaming-oriented projects. Recent credits include Sorcerous Stabber Orphen, Sasaki and Miyano, The Seven Deadly Sins, Pretty Guardian Sailor Moon Eternal The Movie, Pretty Guardian Sailor Moon Cosmos The Movie, Junji Ito Maniac: Japanese Tales of the Macabre, Ōoku: The Inner Chambers, Re:Monster, Welcome Home, Days with My Stepsister, Twilight Out of Focus, and Yakuza Fiancé: Raise wa Tanin ga Ii. Its later announced slate includes additional adaptations and collaborations, indicating that the company remains active as a production and subcontracting studio.
