Diomedéa

Diomedéa is a Japanese animation production company headquartered in Nerima, Tokyo. The studio operates primarily in television animation and related anime production, and is known for work connected with series including Kantai Collection and Girls und Panzer. Its present identity dates from November 28, 2007, when Makoto Kohara recreated the business following the effective closure or reorganization of its predecessor, Studio Barcelona. Much of the predecessor's staff and the same general operational base continued into the new company. The company's institutional history began with Studio Barcelona, which was established on October 5, 2005, by Nobuyuki Suga after a split from the animation company Group TAC. Studio Barcelona was a comparatively short-lived predecessor organization. Under circumstances not fully documented in the cited reference material, it technically ceased to exist and was subsequently re-established as Diomedéa. This transition means that Diomedéa's history is best understood as a continuation of personnel and production capabilities from Studio Barcelona rather than as an entirely unrelated new entrant. Diomedéa's business is centered on animation production rather than consumer retail or a broad entertainment conglomerate structure. Its work can involve the production of television series, original video animation, and films, with responsibilities depending on the production committee and project structure of each title. The studio's output is therefore part of Japan's collaborative anime production ecosystem, in which animation companies work with publishers, broadcasters, distributors, rights holders, and other studios. From 2018 to 2020, Diomedéa collaborated with Studio Blanc under the joint brand Ezóla. According to director Ryousuke Shibuya, Diomedéa's role in that collaboration focused mainly on digital processes, including photography and compositing and digital coloring, while Studio Blanc's personnel handled other parts of the animation work. The arrangement illustrates the studio's participation in specialized, distributed production workflows rather than a model in which every creative and technical function is necessarily performed in-house. The studio's documented representative personnel include founder and president Makoto Kohara, Studio Barcelona founder and president Nobuyuki Suga, director Masakazu Ishikawa, and director Keizō Kusakawa. Beyond these individuals, publicly available reference material identifies Diomedéa through its production history and staff credits rather than through detailed financial disclosures, ownership information, or a large corporate structure. As a result, its scale, current revenue, and precise present-day production slate are not established here.

Diomedéa's history is rooted in Studio Barcelona, an animation organization founded in Japan on October 5, 2005. Nobuyuki Suga established Studio Barcelona after separating from Group TAC. The predecessor appears to have been intended as an independent animation production base, but its corporate continuity was short-lived. The cited account states that Studio Barcelona technically became defunct under circumstances that are not explained in detail, after which Makoto Kohara, a former Studio Barcelona employee, recreated the organization as Diomedéa on November 28, 2007. The change was not a complete break in practical terms. The new studio retained much of Studio Barcelona's staff and continued from substantially the same operational foundation. Diomedéa therefore represents both a new corporate identity and a continuation of the predecessor's personnel and production experience. Suga remains associated with the predecessor as its founder and president, while Kohara is identified as the founder and president of Diomedéa. The studio's documented production scope includes television series, original video animation, and films. As with many Japanese anime studios, its role may vary by project and can include animation production as well as specialized technical work. Existing reference material associates the company with anime titles such as Kantai Collection and Girls und Panzer, although the available material does not provide a complete chronological production list or detailed credits for every title. Between 2018 and 2020, Diomedéa worked with Studio Blanc under the joint brand Ezóla. Director Ryousuke Shibuya described the division of labor as one in which Diomedéa was primarily responsible for digital functions, including photography and compositing and digital coloring, while Studio Blanc's personnel concentrated on the remaining work. This collaboration provides evidence of Diomedéa's involvement in modern, multi-studio production arrangements and highlights digital post-production as one of its identifiable capabilities. The studio's representative personnel include Masakazu Ishikawa, identified as a company director and an animator who had been with the studio since 2007, and Keizō Kusakawa, identified as a director from 2013 onward in the cited reference. Public information supplied for this dossier does not establish Diomedéa's ownership, financial scale, current management beyond the listed roles, or a verified official website. The company is consequently best characterized as a privately held Japanese anime production studio with a history of organizational succession from Studio Barcelona and participation in collaborative animation production.
